Best Backcountry (Touring) Ski Boots of 2025/26

There's a strong argument that the most important part of your ski touring kit is a pair of quality boots that fit well. The good news is that this growing category has seen some impressive advancements, with a plethora of models that excel both on the climb and descent. Below are our top backcountry ski boot picks for the 2025 season, from lightweight builds for deep alpine exploring to downhill-oriented models that can hang at the resort too. Our top picks are the Scarpa Maestrale RS for men and the Scarpa Gea RS for women, which have proven to be the most well-rounded of the bunch. For more background information, see our detailed buying advice and comparison table below the picks. And to complete your alpine touring setup, check out our articles on the best backcountry skis and backcountry ski bindings. 

Editor's note: We updated this guide on November 21, 2025, to trim down our recommendations to a more carefully considered list. We achieved this by reevaluating testing notes and considering use cases for each boot (see the list of dismissed boots below). We also added the Scarpa 4-Quattro Pro to the lineup as our favorite hybrid boot and refreshed existing reviews with new testing notes. Lastly, we ensured all other information was up to date at the time of publishing and included some new imagery from recent testing.

Best Overall Backcountry Ski Boot

1. Men's Scarpa Maestrale RS & Women's Gea RS ($899) 

Category: All-around
Weight per boot: 1460g (men's), 1310g (women's)
Flex: 125 (men's), 120 (women's)
Other flexes: 100W, 110
Range of motion: 61 degrees
What we like: Excellent performance on both the uphill and the descent.
What we don't: Not burly enough and sole not compatible to be a top hybrid choice.

Many backcountry boots favor either uphill or downhill performance, but the Scarpa Maestrale RS and women’s Gea RS have an impressive balance that earns them our top billing for the season. They’re a standout on the skin track with a comfortable fit, lightweight construction, and flexible 61-degree cuff rotation. The Maestrale’s 125 flex (120 for the Gea) offers enough response and control for advanced to expert skiers and a range of terrain and conditions. We’re also big fans of the Intuition liner, which is warm, resistant to packing out, and can be heat-molded for a custom fit. And the cherry on top is the buckle system, which evenly distributes pressure over the front of the foot and provides the support of a 4-buckle boot without the heft.

The Maestrale and Gea were updated last season to include carbon inserts on the shell and cuff for improved rigidity and power transfer, as well as a grippier Vibram outsole. But at its core, these boots continue to be the ones we turn to year after year for their all-around versatility. They are sturdy and powerful enough for most aggressive skiers, compatible with a wide range of bindings and crampons, and feature a comfortable 102-millimeter last (101mm for the Gea) that specifically accommodates the pinky toe, a common hotspot among backcountry riders. The main drawback is its lack of crossover appeal: the sole isn’t compatible with alpine bindings, and the 125-flex (120 for the Gea) isn’t the most aggressive for expert in-bounds riders. The Maestrale and Gea are also quite expensive (though, we’re glad to see the price has decreased this season), but if you want to save a bit of cash, Scarpa also offers a standard Maestrale and standard Gea, at the sacrifice of flex (110 for the Maestrale; 100 for the Gea).

Best Budget Backcountry Ski Boot

2. K2 Mindbender 100 Boa ($650)

Category: Hybrid
Weight per boot: 1796g (unisex)
Flex: 100
Other flexes: 95W, 105W, 110, 115W, 120, 125W, 130, 140
Range of motion: 50 degrees
What we like: Solid entry-level backcountry boot at a great price.
What we don’t: Not for long-reaching tours.

Touring boots are undeniably expensive, but K2’s Mindbender 100 is a solid entry-level boot for skiers splitting time between the resort and backcountry. Beginners should prioritize comfort above all else, and the Mindbender’s generous last and heat-moldable liner and shell help ensure a good fit. Compatibility with both alpine and tech bindings helps those who want to try out backcountry skiing but aren't ready to fully commit. And the latest version features a Boa closure around the front of the foot for precise tightening. Add it all up, and the K2 Mindbender 100 ticks all the boxes for beginner skiers on a budget.

Considering the great price—for a backcountry boot, at least—you can expect a few drawbacks. To start, the Mindbender is far from the lightest boot on this list, which makes it a chore to haul up steep tracks. Its 50-degree range of motion is only average, and it doesn't have the friction-free performance of higher-end alternatives. And on the downhill, it lacks the precision and power that you get with a stiffer design (K2 does make 120-flex and 130-flex versions). It’s worth noting that we opted not to include the women’s Mindbender 95 here because it’s significantly more expensive than the 100, and we believe most women would find the 100 acceptable, especially considering it features the same 100 millimeter last. For an alternative in this space, check out Scarpa’s 4-Quattro GT (also available in women’s), which is a bit pricier than the Mindbender, but it has a stiffer 110 flex for men (90 for women), warmer liner, and more accommodating last. At the end of the day, serious riders should stick with the higher-end models on this list, but the Mindbender is a solid choice for adventurous resort skiers who want to dabble in the backcountry.

Best Hybrid Backcountry/Resort Boot

3. Scarpa 4-Quattro Pro ($899)

Category: Hybrid/All-around
Weight per boot: 1555g (unisex)
Flex: 130
Other flexes: 90W, 100W, 110, 120
Range of motion: 60 degrees
What we like: Well-rounded performance for backcountry and resort use.
What we don't: Too heavy for dedicated backcountry skiers, too stiff for intermediate skiers, and no women’s specific version.

Truth be told, many backcountry skiers split their time between touring and the resort. The good news for these folks is that there are a growing number of one-quiver boot options, including Scarpa’s 4-Quattro Pro. In testing, this boot has proven itself very capable of keeping up both in and out of bounds. To start, at just 1555 grams per boot, the 4-Quattro Pro is light enough to remain nimble on the skin track, and the 60-degree range of motion matches that of our top pick. Additionally, the stiff 130 flex and four-buckle design offer lots of drive and responsiveness for expert skiers. We also like Scarpa’s latest take on the cuff, which has a rigid reinforcement on the back and is lower at the front for more effective power transfer. Put together, the 4-Quattro has a lot of appeal for those who split their time between the lifts and the skin track and are unwilling to sacrifice performance in either setting.

The 4-Quattro toes the line better than most, but as with any all-in-one option, there are some compromises. To start, dedicated uphill enthusiasts will likely want a lighter boot (at the sacrifice of downhill performance). The Pro version of the 4-Quattro is also only available in a stiff 130 flex, but you can opt for the less stiff 4-Quattro SL or aforementioned 4-Quattro GT and save a bit of cash in doing so. Similarly, there is no women’s version of the Pro, which some women might find too stiff. The closest alternative is the women’s version of the 4-Quattro SL, which has a flex of 100. It’s also worth mentioning here Atomic’s Hawx Ultra XTD 130, which is another popular hybrid boot. But while the Hawx is a fantastic boot for the downhill, we think the 4-Quattro has greater appeal on the skin track thanks to its lighter weight and better range of motion, making it the clear choice for do-it-all skiers.

Best Freeride Backcountry Boot

4. Men's Tecnica Zero G Tour Pro & Women's Zero G Tour Pro ($980) 

Category: All-around/Freeride
Weight per boot: 1290g (men's), 1180g (women's)
Flex: 130 (men's), 125 (women's)
Other flexes: 105W, 110, 115W, 120
Range of motion: 65 degrees
What we like: Very lightweight for a stiff, aggressive boot.
What we don't: Not an entry-level boot; high price tag.

Tecnica’s Zero G boots are some of the most sought-after designs among committed backcountry riders, and the Tour Pro is the most premium of the bunch. Between its thin Grilamid shell and carbon fiber-reinforced cuff, the Tour Pro is purpose-built to be both lightweight and stiff. Its 65-degree cuff rotation beats out other premium offerings, like the Maestrale above, and gives it a lot of flexibility and comfort on steep skin tracks. But the 130 flex (125 for the women’s) offers plenty of precision and power for advanced and expert riders. There are a few other bells and whistles in the latest version as well, such as the wide-opening cuff that makes for quick entry and exit. The grippy Vibram outsole offers a lot of underfoot confidence, and the walk lever connects in two places when toggled to ski mode, offering even more assurance on burly descents.

The Tour Pro is an intriguing design for confident riders, but it’s not without downsides. To start, it has a narrow 99 millimeter last that won’t accommodate all feet, especially wide ones. We also found the overlapping shell tough to get into—eventually, we figured out it's easier to put the liner on first, then the shell. The hook on the power strap kept wiggling loose during testing, and we eventually had to replace it. Lastly, it’s worth noting that the Tour Pro requires a capable pilot. It has a stiff and unforgiving build that will overpower those with less experience. If you’d prefer something less intense, Tecnica also offers the Zero G Tour Scout and standard Tour, which have 120 and 110 flex ratings, respectively.

Best Lightweight Ski Touring Boot

5. Men's Scarpa F1 LT & Women's Scarpa F1 LT ($899) 

Category: Lightweight
Weight per boot: 990g (men's), 930g (women's)
Flex: 100 (men's), 95 (women's)
Other flexes: None
Range of motion: 72 degrees
What we like: A lightweight and capable boot for high-mileage days.
What we don’t: Thin construction impacts warmth and durability.

The original Scarpa F1 amassed a loyal cult following of light and fast ski mountaineers almost overnight. So when Scarpa announced the F1 family was expanding to meet the specific needs of different Dyneema-backpack-wearing skiers of all varieties, you can imagine the excitement. The F1 LT is the love child of two of Scarpa’s classics, the skimo-focused Alien and the original F1, resulting in a ridiculously capable alpine touring machine. For uphill pushes and long traverses, you get a 72-degree range of motion and a feathery-light weight of 990 grams per boot (930g for the women's). And when the descents get technical (as they tend to in the mountains), the F1 LT is a predictable partner with a solid Carbon Grilamid shell and cuff, and a 3D Lambda Frame that gives it a progressive flex (at least relative to its weight).

The F1 LT goes head-to-head with boots like the Dynafit TLT X and Atomic Backland Carbon below. But between its light weight and soft 100 flex, the F1 LT is far from a performance downhill boot. Warmth and durability are also concerns, though we haven’t experienced any serious issues yet. If you find yourself wanting for something a little stiffer, the F1 XT has a similar build but a 110 flex. But you’d be hard-pressed to find a lighter touring boot than the F1 LT that doesn’t sacrifice features like a full shell and cuff. For those wanting an uphill rocket, it’s definitely worth having on your shortlist.

All-Around Boot With a Quick Transition System

6. Men's Dynafit Radical Pro & Women's Dynafit Radical Pro ($900)

Category: All-around/Freeride
Weight per boot: 1400g (men's), 1270g (women's)
Flex: 120 (men's), 110 (women's)
Other flexes: 100W, 110
Range of motion: 60 degrees
What we like: A great all-around boot with a quick-transition system.
What we don’t: Stock liners pack out too quickly.

The Radical Pro has proven itself to be a great all-around touring boot, similar to the Scarpa Maestrale above. It’s lightweight and flexible enough to cruise up the skin track, and stiff enough to tackle a range of terrain on the descent. What sets it apart is the Hoji Lock System, which seeks to shorten the time spent on transitions. The mechanism is fairly simple: when the back lever is set to walk mode, the top buckle loosens, and the cuff and shell are separated, allowing for freedom of movement along the skin track. And when it’s time for the descent, the lever is pushed down, which tightens the front buckle and connects the cuff and the shell, providing stiffness and support for the ride down. Over the years, this design has become a favorite among guides and ski professionals who spend long days in the backcountry, but it also has a lot of appeal to yo-yoers who transition several times throughout the day.

That said, there are several reasons we rank the Maestrale above the Radical Pro. To start, the Maestrale is a better choice for hard-chargers, thanks to its stiffer build and more aggressive forward lean (16 degrees vs. 11 degrees for the Radical Pro). The 104 millimeter last is also the widest on this list, and isn’t as accommodating as the Maestrale’s middle-of-the-road 101 millimeter last (especially for those with narrow feet). If you like the look of the Radical Pro but want something softer and less expensive, Dynafit also makes a standard Radical in a 110 flex for men, and a 100 flex for women. Both feature a more basic polyurethane cuff (the Pro uses fiber-reinforced Grilamid) and drop the Hoji Speed Lock system for a more traditional boot design.

Lightweight and Cost-Effective

7. Men's Dynafit TLT X & Women's Dynafit TLT X ($500)

Category: Lightweight
Weight per boot: 1030g (men's), 930g (women's)
Flex: Unavailable
Other flexes: Unavailable
Range of motion: 60 degrees
What we like: Great price, super lightweight, and quick to transition.
What we don't: Downhill performance is sacrificed for uphill efficiency. 

Short for “Tour Lite Tech,” Dynafit’s TLT collection has helped to define modern ski touring as we know it. The already very lightweight TLT X was updated last season to further reduce its weight—now sub-5 pounds total for the pair. The latest version also features a Boa-like lacing system (Dynafit calls it “Twistfit”), which securely snugs the boot around the instep and heel, and the sleek upper buckle both adjusts the cuff and quickly transitions between ski and tour modes. The X also boosts comfort with a wide 101-millimeter last and a cushier liner, which is a step up from the minimalist liner of the previous version. While the flex is not rated by Dynafit, we think it's close, possibly a bit softer, than the Scarpa F1 LT above.

Who is the TLT X for? Despite what the budget price tag might suggest, we don’t recommend it for beginners. Rather, the TLT X is best suited for experienced ski mountaineers who are willing and able to give up support and comfort for weight savings. The downhill performance falls far behind the stiffer models here, and it can be difficult to drive in poor snow conditions. The K2 Mindbender is a much better choice for those just getting started. We also think that experienced riders will get a lot more enjoyment out of a boot like the Scarpa F1 LT above or the Atomic Backland below. But if your main goal is uphill efficiency—say, you’re trying to set FKTs on volcanoes in the springtime—then it doesn’t get much better than the TLT X.

A Great Combo of Uphill and Downhill Performance

8. Atomic Backland Carbon ($890)

Category: Lightweight
Weight per boot: 1162g (unisex)
Flex: 110
Range of motion: 74 degrees
What we like: Impressive combination of range of motion and flex.
What we don't: Not a standout option in either category.

While many of the boots on this list have a clear performance bias for either the uphill or the downhill, Atomic’s Backland Carbon aims squarely for the middle ground. Between a feather-light construction and a very flexible range of motion, the Backland is a high performer on the skin track, giving heavier and stiffer all-arounders like the Maestrale above a run for their money. Atomic keeps things light with a two-buckle design, but a cable along the forefoot distributes pressure evenly for a snug fit. The 110 flex is on the softer side to be sure, but our tester has found it plenty supportive for sweeping turns down volcanoes and navigating the trees down low (he skis the Faction La Machine 1, for reference). We’re also big fans of the washable liner, which does a great job at absorbing sweat when you’re hoofing it up steep tracks. The boot also has a durable construction, and has held up well to several seasons of rough use.

Like most jack-of-all-trades designs, the Backland Carbon isn’t the best in one particular category. The Scarpa F1 LT and Dynafit TLT X above are both lighter weight than the Backland (though, the Backland does have them beat on cuff rotation), and the Maestrale has a stiffer flex for better downhill performance. If you want something else in this space that leans slightly more towards downhill performance, check out Dynafit’s Ridge Pro, which we tested and enjoyed last season. The Ridge Pro is heavier than the Backland Carbon, but has a stiffer 120 flex (110 for women). Our other concern with the Backland Carbon is fit: Its 98 millimeter last is very narrow and won't fit wider feet. But so long as it fits (we suggest trying on before buying), the Backland does “do it all” better than most.

A Budget Hybrid Boot

9. Dynafit Tigard 130 ($800) 

Category: Hybrid
Weight per boot: 1590g (unisex)
Flex: 130
Other flexes: 110
Range of motion: 70 degrees
What we like: An impressive balance of freeride performance and touring capability at a good price.
What we don't: Build quality isn’t the most premium.

Dynafit’s Tigard 130 offers a compelling alternative to the Scarpa 4-Quattro above. Just like the 4-Quattro, it does a better job than most hybrid boots at balancing backcountry and inbound appeal. For the downhill crowd, the Tigard boasts a sturdy 130 flex and 13 degrees of forward lean. The Grilamid and carbon shell fully wrap the foot in a way that’s reminiscent of alpine ski boots. And the uphill enthusiasts get an impressive 70 degrees of cuff rotation and a relatively low weight (for a hybrid boot). And like the Radical Pro above, the Tigard has Dynafit’s Hoji Lock System, which makes transitions a breeze. The cherry on top is price, which undercuts the 4-Quattro by a decent amount.

What do you give up in going with the Tigard? In our experience, build quality. Scarpa’s attention to detail and material quality generally surpasses Dynafit’s. For example, the Intuition liner on the 4-Quattro is higher quality and likely to last a lot longer than the Tigard’s in-house liner. We’ve also had better luck with the traction on the bottom of the 4-Quattro, which covers more of the boot—the Tigard has a large amount of plastic between the traction on the toe and the heel, which doesn’t make it the best choice for more technical backcountry days. And though not by much, the 4-Quattro is lighter. At the end of the day, we think the 4-Quattro pulls off versatility better than the Tigard, but that’s not to say that the Tigard is a bad boot. If your budget is tighter, it’s a great alternative that doesn’t sacrifice much in performance.

For the 80/20 Resort/Backcountry Skier

10. Men's Salomon Shift Alpha 120 & Women's Shift Alpha 115 ($890)

Category: Hybrid
Weight per boot: 1758g (men's), 1673g (women's)
Flex: 120 (men's), 115 (women's)
Other flexes: 95W, 110, 115W, 130
Range of motion: 55 degrees
What we like: Alpine boot-like design and performance.
What we don’t: Relatively limited range of motion.

Salomon’s Shift series is most well-known for the Shift binding, which is a hybrid binding for both resort and backcountry use. The Shift Alpha Boa follows a similar recipe with an alpine-level downhill performance and backcountry feature set. The boot has a beefy two-buckle and Boa closure system (the former on the cuff, and the latter along the foot), a sturdy shell, and a warm liner. The fit is among the most customizable on our list thanks to Salomon’s Custom Shell HD, which is easy to heat mold for a personalized fit. On the uphill, the Shift Alpha checks the right boxes with an easy-to-access hike lever, tech inserts, and GripWalk soles for reliable traction.

Who is the Salomon Shift Alpha best for? With its powerful and sturdy build, the design caters more to the resort crowd that mixes in the occasional half-day tour. The boot is among the heaviest on this list, and the 55-degree range of motion falls short of the more backcountry-focused designs above. Simply put, if you’re planning on spending most of the day with skins on your skis, the Shift Alpha won’t be the best option. But if you’re a resort skier who likes to dabble in a bit of backcountry now and again, the Shift Alpha is a compelling design. And so long as you don’t mind some heft on the way up, they’re sure to make for a fun descent.

Tested & Dismissed Backcountry Ski Boots

Competition's tough in the backcountry ski boot market, and manufacturers are constantly revamping old designs or dropping new models that are lighter, stiffer, or more convenient to try and stand out. We test multiple new backcountry ski boots each year, but not every one makes the cut. We have high standards for our lists, and want to recommend boots that offer the best combination of price and performance. But we understand that you may be curious about what boots we've tested and decided not to include.

To start, we opted to remove the Atomic Hawx Ultra XTD 130 from this list because the Scarpa 4-Quattro Pro proved to be a better hybrid design in practice. Hawx is much heavier and falls behind the 4-Quattro's range of motion, which limits its appeal for the skin track. We also prefer the 4-Quattro's standard buckle closure over the double Boa on the Hawx, which are tougher to service in the backcountry if they break. The Hawx isn't a bad boot by any means, but considering its hefty cost, it just doesn't stand out in the hybrid space.

We also removed the Dynafit Ridge Pro from our list, which was our favorite new release for last season. We enjoyed the boot in testing, but felt that the Atomic Backland Carbon did a better job at balancing weight savings and downhill performance. 

The Lange XT3 Free 130 also didn't make the cut this update because, like the Hawx, it falls short of the 4-Quattro Pro as a hybrid boot. It's heavier and doesn't have as much range of motion in the cuff. The 4-Quattro is a more versatile choice.

The K2 Dispatch Pro was also removed from our list this season because it isn't competitive against the Technica Zero G Tour Pro, which is a lighter-weight freeride boot with a better range of motion at a lower price. And in our testing, it didn't match the downhill performance of the Zero G.

We also opted to cut the Rossignol Attrack Elite 130 LT from the list because it doesn't stack up to other hybrid boots on this list. The 50-degree cuff rotation is very limiting on the uphill, and the boots weigh much more than the competition. For the price, it's worth sticking with the Dynafit Tigard 130.

Lastly, we tested the Fischer Transalp Carbon Pro 130 last season but decided not to include it in this list because we found its downhill performance to be disappointing. It was light and nimble on the uphill, but felt very flimsy and untrustworthy on steep descents—it didn't live up to its claimed 130 flex or high price tag.

About Our Testing Process

Skiing is a favorite activity for many of the editors at Switchback Travel, and our team runs the gamut of experience levels. From those who are relatively new to those who have been skiing since they could walk, we know how to assess and recommend the right gear for all skill levels. This guide was launched in 2019 as a collaborative effort, until freelance writer and gear tester Alli Hartz took over as the manager in 2022. Working with a staff editor, we pieced together a well-organized splay of top picks from every part of the backcountry market. Based in Bend, Oregon, Alli shares her love for skiing through teaching avalanche courses and ski guiding in the winter months. Editor Maddie Downie now manages the guide. Maddie is based in Bellingham, Washington, and battles the winter blues by hoofing it up steep skin tracks in the North Cascades every chance she has. 

Our current lineup of 10 pairs of backcountry boots above is the result of ongoing testing, feedback from our freelance testers, and extensive research. Given the rapidly growing amount of offerings for backcountry boots, we’ve included a relatively wide variety of options, varying in last, flex, and use cases. To make our list, each boot had to stand out in one or more areas, with many striking an effective balance between performance, use, and durability. And if you're looking to complete your setup for the season, know we took a similar approach with our lineup of touring skis and backcountry bindings.

What Are Backcountry Ski Boots?

Backcountry ski boots, otherwise known as AT (alpine touring) boots, are designed specifically for use in areas with no chairlift access. They differ from standard downhill (alpine) models in a few ways, the most notable of which are binding compatibility and uphill capability. Whereas a downhill ski boot typically is only compatible with an alpine binding that keeps both the heel and toe locked in at all times, a backcountry ski boot is used with a touring-specific binding that secures the toe and allows you the option of freeing the heel of the boot for uphill travel on skis. 
 

In order to travel uphill, backcountry ski boots also feature a walk mode, which allows the boot to pivot at the ankle with each stride. In the vast majority of cases, this is toggled via a lever along the spine of the boot. While in walk mode, you get a sufficient range of motion for skinning and boot packing, differing in amount and comfort by boot model. Locked into place, the boot resembles a standard downhill design with enough stiffness to transfer power to the bindings and skis. The competing demands of weight and flexibility on the climb (and therefore comfort and natural movement) with stiffness and control on the descent mean alpine touring boots are complex and incorporate high-end materials like Grilamid, Pebex Rnew, and carbon fiber. This leads to expensive price tags that often exceed $900, but a quality design that fits your feet well can be an amazing companion for exploring the backcountry.

Backcountry Ski Boot Categories

Most ski brands want you to believe that their backcountry gear compromises nothing on the uphill or downhill. In a perfect world, an alpine touring boot would be both lightweight and flexible on the uphill and stiff and supportive when bombing down steep terrain. We don't live in a perfect world, however, and although some boots come close, the reality is that you'll always be sacrificing a bit of downhill prowess for uphill comfort—or vice versa. As a result, we've put backcountry ski boots into four general categories: "all-around" for boots that try to achieve that elusive all-in-one solution for backcountry demands, "lightweight" for those that prioritize climbing efficiency and low weight above all else, "hybrid" for those that feature alpine-worthy downhill performance and are advertised for in-bounds use as well, and "freeride" to reflect the increasingly diverse set of needs among hard-charging backcountry riders. Below, we break the styles down in greater detail.
 

All-Around
Our all-rounder category is home for standard touring designs that meet all the needs of a typical day of skiing in the backcountry: You're probably not attempting to set any FKTs (Fastest Known Times), but your ascent is likely completely human-powered. For this healthy mix of downhill and uphill, you need a boot that can excel at both—that proverbial perfect world. Alpine touring boots are characterized by this balance, featuring lightweight builds, a high range of motion in walk mode, a stiff ski mode, compatibility with crampons and tech bindings, and grippy soles. A boot like the Scarpa Maestrale RS (and women's Scarpa Gea RS) is able to pull off all of these features. This best-of-both-worlds scenario tends to warrant a higher price tag, but for folks who seek a true backcountry experience with big ups and big downs, it's worth the investment.
 

Lightweight
More than any other style of touring boot, lightweight designs for ski mountaineering or deep backcountry exploration prioritize uphill travel. They are characterized by a minimalist build, a high range of motion (often both lateral and vertical), minimal buckles and weight, crampon compatibility, tech binding fittings, and grippy soles. The low weight and increased range of motion of these boots (as well as typically softer flex) can make skiing down feel a little insecure, especially on icy or hard-packed terrain. Thus, these boots are perfect for long days in the mountains when uphill travel or long mileage is the goal, but they're certainly not for frequent use in bounds. The Scarpa F1 LT and Dynafit TLT X are two of our favorite lightweight boots.
 

Hybrid
In skiing, the word “hybrid” refers to a piece of gear that bridges the gap between the resort and the backcountry (the term “50/50” is also commonly used). A hybrid boot is an ideal option for backcountry-curious resort skiers who want the option to ski out of bounds from time to time (the backcountry terrain adjacent to the resort is often referred to as the sidecountry). Because the sidecountry often necessitates far less uphill travel than other forms of backcountry skiing, an ideal hybrid boot will prioritize stiffness and stability on the downhill over uphill comfort and weight savings. You'll see an increase in weight, bulkier designs, less range of motion, four buckles, a slightly more forward lean, and compatibility with alpine bindings. Hybrid boots also excel for aggressive skiers who want a burly and reliable option for big-mountain backcountry adventures with mechanized access using a snowcat or helicopter, though these types of skiers may also start to be interested in the newly emerging category of freeride backcountry boots. Options like the K2 Mindbender, Scarpa 4-Quattro Pro, and Salomon Shift Alpha fit squarely into this category.
 

Freeride 
While the hybrid category used to encapsulate both the hybrid and freeride use cases for touring boots, times are a-changing. With more highly developed technology and both professional and homegrown darkhorse athletes pushing what can be done on skis deep in the mountains as much as they are in-bounds on the Freeride World Tour, a new category of backcountry-specific boots is now emerging. These boots are meant explicitly for the backcountry but are also meant for skiing fast, going big, and stomping the landing. These boots won't promise compatibility with downhill bindings like hybrid boots and will have better walkability and uphill design. Boots like the Dynafit Radical Pro fit this category well—they will still excel on the downhill, but don't expect them to be as good of hiking companions as lightweight boots like the Scarpa F1 LT.
 

Backcountry Ski Boot Weight

The weight of a ski boot makes a significant difference in comfort and energy conservation throughout a day in the mountains. Whereas the typical weight of an alpine ski boot design can hover around a hefty 5000 grams (11 lbs.) per pair, an average backcountry model weighs around 2750 grams (just over 6 lbs.) and can drop as low as below 1000 grams (2.2 lbs.) for a ski mountaineering setup. If traveling uphill comfortably and efficiently is the goal—without overly compromising on the descent—there are a number of excellent options in the 2270 to 3200-gram range. For short tours or strong riders who prioritize downhill performance (including sidecountry enthusiasts), a good benchmark for your pair is approximately 3700 grams (about 8.2 lbs.) or under. However, as the market continues to evolve, better performance options are emerging with lower weights. But when you creep above that point, uphill travel can become an uncomfortable and overly exhausting activity for the average skier.
 

Flex Rating

The flex rating describes how much pressure must be applied to flex your boot forward at the ankle while in ski mode. A lower number means the boot is softer, while a higher number means the boot is stiffer, and you'll find numbers ranging from 70 at the low end for a super soft beginner alpine boot up to 130+ for an expert model. It's worth mentioning that there isn't a standardized test to establish these ratings—it's up to the manufacturer to list them. This means flex ratings are not exactly created equal amongst different manufacturers, but for the most part, we've found the flex rating to be a helpful tool (and we call out any boots that don't seem to match their given rating in the write-ups above). With downhill boots, typically less experienced skiers will prefer a boot on the soft side, while advanced skiers will want the power transfer and stability of a stiffer boot. Beginners should understand that although a softer flex in a downhill boot generally means it is for newer skiers, softer flex touring boots are not aimed at the same market. The Scarpa F1 LT is a great example here. With a 100 flex rating to save weight on far-reaching backcountry pursuits, the F1 LT is not going to be a good match for a beginner to intermediate skier, while the downhill-specific K2 Mindbender 100 (same flex) would be perfect.

To reiterate: Backcountry ski boots tend to be less stiff than alpine boots for a number of reasons. First, backcountry skiers are more likely to seek out powder than hard snow—and powder doesn't require as much power transfer as hardpack. Additionally, touring boots are typically manufactured with lighter materials, which makes them softer in general. Because of this, a backcountry ski boot's flex rating won't always translate perfectly to the flex rating of an alpine ski boot (for example, a backcountry boot with a stated flex of 110 might feel slightly softer than an alpine ski boot with the same given flex number).
 

Below are some very general recommendations for ski boot flex based on ability level; however, it is important to note that there is no recommendation for beginner skiers. While we are all for inclusivity and think everyone has a place in the backcountry (eventually), if you are truly a beginner skier, you need time at a ski resort learning to move downhill in a controlled environment before going out of bounds. There are so many pieces of knowledge on top of gear to operate to just get by on a basic day in the backcountry—avalanche danger, avalanche rescue skills, techniques to manage variable conditions, terrain management, etc. You need to at least be confident in your ability to get downhill safely to be able to have enough bandwidth to manage all of the other essential parts of a day of being in the backcountry.

Intermediate: 90-110
Advanced: 100-120
Expert: 120+

More recently, many ski gear manufacturers have introduced a range of flex options for individual boot models, enabling users to select the perfect stiffness for their level, weight, and ankle flexibility. For example, the Atomic Hawx Ultra XTD is available in 100, 120, and 130 flex ratings for men, and the women’s version has 95 and 115 variations. Further, you’ll see prices rise as flex ratings increase, due to the more premium materials and design of a stiffer boot. When applicable, we mentioned the various flex options available for each boot in the individual write-ups above. 
 

Walk Mode and Range of Motion

You've likely heard the phrases "earn your turns" or "you've gotta get up to get down." However you choose to say it, backcountry skiing is just as much (if not more) about the uphill as it is about the downhill. If you're truly touring—not using lifts for accessing the sidecountry—then you'll spend somewhere around 75% of your time on the uptrack. For this reason, all backcountry ski boots are designed with two modes: a walk mode (increased range of motion for uphill travel) and a ski mode (stiff and supportive for descents). Each boot has a way of locking into ski mode or releasing into walk mode, usually by way of a lever on the back that engages and disengages with a flip. 
 

Walk mode and range of motion go hand-in-hand: This specification describes the amount of fore/aft motion available in a ski boot while in walk mode. The range of motion (ROM)—also known as cuff rotation—is defined by several factors, including the materials used in the boot's design and the amount of play allowed in these materials. But it's important to note that soft materials and a high range of motion create inherent weakness in the structural integrity of a boot. Thus, while boots with a greater range of motion will be more comfortable on long ascents, they aren't able to provide as much support on the descent as a boot with harder materials or lower cuff rotation. 
 

The range of motion specification is a good number to pay attention to when thinking about how much of your ski day will be uphill-focused. If you are more interested in full days in the mountains with big ups and long traverses, a greater range of motion like what you get with the Atomic Backland Carbon (74 degrees) will help preserve energy in your legs, get the most out of each stride, and will be more comfortable in general. If the goal is long, potentially steep descents, and you aren't feeling confident in softer boots like a pro skimo racer, opt for a boot that sacrifices range of motion for a higher flex rating. Boots such as the Scarpa Maestrale RS (61 degrees) and the Dynafit Radical Pro (60 degrees) offer a good mix of both.
 

Buckles

Buckles are yet another place where manufacturers can make decisions that affect the uphill vs. downhill performance of a boot. Whereas a standard alpine ski boot has four buckles, a backcountry boot can have anywhere from two to four. Fewer buckles mean less weight, which is certainly helpful for uphill travel. However, fewer buckles also mean you'll sacrifice power and rigidity on the descent. Skiers more interested in uphill travel can get away with a boot with fewer buckles, while skiers more interested in making solid downhill turns will feel more confident with three or four buckles. Additionally, most backcountry-specific ski boots are manufactured with a removable "power strap," a thick piece of Velcro located near the top of the cuff. This strap adds significant support for aggressive downhill skiing, particularly on harder snow. However, since it also adds weight and is not needed for uphill travel, some manufacturers prefer to remove the strap altogether. 
 

In terms of buckle design, most boots are built with a classic aluminum buckle with a ladder and catch bail, but more and more we're seeing different configurations and technologies. Many recent innovations allow for more support without more ounces. The Scarpa Maestrale RS, for example, combines two buckles with one strap for a lightweight setup that spreads pressure out along the entire top of the foot. Other boots utilize a Boa buckle closure to fine-tune the fit with a simple twist, such as the Dynafit Ridge Pro. Regardless of the closure system, it is important to practice buckling, unbuckling, and adjusting your boots before heading into the mountains. You'll likely be dealing with your buckles a lot as you transition from uphill to downhill and vice versa, and you'll want to be efficient when temperatures drop and the wind starts howling.
 

Boot Fit and Sizing

Perhaps the single most important aspect of a ski boot is how it fits your foot. We highly recommend trying on multiple pairs before purchasing, as every manufacturer builds boots with a specific shape that will fit some feet better than others. The main challenge will be finding the ideal balance of a snug yet comfortable fit. If it's too roomy, a boot will not offer the needed support for downhill skiing. If sized too tight, it will (at best) be uncomfortable during long days in the mountains, but more likely, it will cut off circulation and create dangerously cold feet. If you're transitioning from alpine skiing to alpine touring, keep in mind that you'll want to size your boot a bit looser than you might be accustomed to. With little opportunity to take your boots off throughout the day and the need to skin or hike uphill, you'll want to prioritize comfort and a good fit above all else.

Mondopoint
Ski boot size is delineated by the Mondopoint—aka-Mondo-scale—which refers to the length of your foot in centimeters. You can measure your own Mondo size quite easily by putting your foot against the wall, marking where your toes end, and measuring the distance in centimeters. Most ski boot shells are built only in full-size increments, whereas liners come in half sizes. If you're a Mondo size 25.5, for example, you'll get a size 26 ski boot shell with a size 25.5 liner. You can use a conversion chart to determine your Mondo size, but we still highly recommend getting fitted by a ski boot professional.
 

Last
Whereas a boot's Mondo size refers to the length of the foot, the last refers to the foot's width in millimeters. Many traditional alpine ski boots are available in two to three different lasts to accommodate various foot sizes, but backcountry ski boots don't usually offer this option. Because of this, when shopping for a boot, you'll want to make sure you choose a model made with a last that fits your individual foot. Those with wider or higher volume feet should look for boots with lasts 100 millimeters and up, and those with narrower feet will be happy with a last between 95 and 98 millimeters. Again, it's worth repeating that this information is good for planning purposes, but can't come close to the value of getting fitted by a reputable ski shop.

Customization
Like their alpine counterparts, most touring boots can be customized through heat molding, punching, grinding, etc. In most cases, the liners can be heat-molded, which we prefer to do at our local ski shop. But because alpine touring boots are intended for extended time on your feet—walking, gliding, possibly kicking in steps, skiing, and some standing around during transitions—you’ll want to try to start out by choosing boots that are fairly comfortable right out of the box. Hard-to-fit feet may require some customization, but if your touring boots require extensive work, you might be better off with a different pair altogether. We recommend working with a professional boot fitter, trying on multiple pairs of boots before purchasing, and getting any customization done at a ski shop with the proper equipment. 

Women's-Specific Ski Boots

Most ski boots are technically unisex, but some manufacturers have chosen to offer touring models specifically for female skiers. Some of these have different monikers—for example, the women's version of the Scarpa Maestrale RS is called the Gea RS—while most go by the same name. The question is: What are the differences between a women's and men's ski boot?
 

In reality, there are not as many differences as you might think. Women's boots feature graphics that may (or may not) hold more marketing appeal for the female ski community. In addition, women's boots usually come in smaller sizes (for instance, the Scarpa Gea RS starts at a size 22.5, while the Maestrale RS starts at 24.5). But most importantly, many women's-specific boots have lower flex ratings that make them softer. All of this assumes, of course, that women prefer different graphics, have smaller feet, and want softer boots—which is certainly not always the case. Some women are quite aggressive and want stiffer flex boots for the backcountry, and slowly the market is catching up to the ladies' capabilities with touring boots like the Tecnica Zero G Tour Pro, a 125 flex women's specific touring boot.

The bottom line is that each ski brand makes its boots with a unique shape, fit, and features. The men's and women's models embody the distinct qualities the brand aspires to offer. If you identify as a female and have found the perfect pair of boots that only come in a men's model, try them on, and don't be afraid to go for it (and vice versa). As long as they feel snug and comfortable, they'll provide you with the backcountry ski experience you're looking for. While body weight and ability affect the flex of the boot you should be skiing, other factors like ankle flexibility (women often have more flexible ankles) also factor into this selection. 
 

Boot Liners

A backcountry ski boot is designed with both an outer shell and an inner liner. The shell is responsible for structure, while the liner is built to conform to the foot and provide both comfort and warmth. Most boot liners are a classic slip-on with a forward tongue, while some have a lace or Boa closure for added support. Finally, some liners do not have a tongue at all. In general, the type of liner you choose comes down to how secure and adjustable you like your boot to feel.

One of the most important features of a boot liner is the foam that is sandwiched between the shell and inner lining. On the budget end of the spectrum are open-cell foam designs, which are comfortable at first but tend to pack out quickly. They also take some time to dry, which can make for an extremely cold day as your sweat starts to freeze. On the other hand, some premium offerings include a more expensive closed-cell foam liner—for example, the Intuition Pro Flex Tour in the Scarpa Maestrale RS. These liners keep their shape and cushioning much longer than those of the open-cell variety. What's more, they dry very quickly and tend to keep your feet warmer, even during the coldest days. If your ski boots come with an open-cell foam liner, we have found it to be worth the price (especially for those who run cold) to buy a closed-cell foam liner separately. 
 

One final note regarding insoles: Most ski boots, whether made for alpine or alpine touring, contain a thin piece of foam in the bottom of the liner. When you’re spending a good portion of your day on your feet, especially when it involves walking, the factory insole that comes with your boot will not provide sufficient support for your arches and foot muscles. Investing in a pair of quality insoles (such as Superfeet) will go a long way in adding comfort, reducing foot fatigue, and contributing to a better fit within your boot’s insole. 

Binding Types and Compatibility

This is about as intricate a topic as you can get into while pairing your backcountry setup, which is why we wrote an entire ski boot binding and compatibility guide about it. There are three categories of backcountry ski bindings: tech, frame, and hybrid (you can read more about the pros and cons of each in our article on tech vs. frame bindings). The style of boot you choose will influence which binding you'll pair it with, and vice versa. Tech bindings, otherwise known as pin bindings, are the most common form of backcountry ski binding. These designs are also the lightest of the bunch (most versions range from 1000 to 1400g for the pair), feature separate heel and toe pieces, and are only compatible with boots that have tech fittings at the toe. Due to their lightweight builds and pivot point near the ball of the foot that allows for a natural stride, tech bindings are our first choice for skiers who spend most of their time in the backcountry, and especially those who want to move efficiently uphill. Downhill performance ranges from serviceable to very good, depending on the specific binding.
 

Frame bindings are essentially traditional downhill bindings attached to a rail that extends from heel to toe. This rail attaches and releases from the heel, allowing for both uphill and downhill movement. Importantly, frame bindings don’t require boots to have tech fittings, which means you can get away with using an alpine boot with a walk mode. The most notable compromise with frame bindings is uphill performance: They are very heavy (weighing anywhere from 1600 to almost 3200g), and the placement of their pivot point in front of your toe results in an unnatural stride and reduced efficiency on the skin track. With more capable tech and hybrid designs on the market than ever before, frame bindings are at risk of becoming obsolete and aren’t our first choice for most skiers. That said, if you’re on a strict budget or ski mostly inbounds, a frame binding could be the best option.

This brings us to the third category (also the newest): hybrid bindings. Hybrid backcountry bindings are really defined by two key designs: the Salomon S/Lab Shift 2.0 MNC and Marker Duke PT. Along with an alpine heel, these bindings feature a toe piece that functions like a tech toe on the uphill but converts into a traditional downhill design when in ski mode. This means a few things: For one, you get incredible downhill performance and safety with a fully locked-in toe, on par with a standard alpine binding (both the Salomon and Marker are TÜV-certified for DIN). Second, hybrid bindings are incredibly versatile in terms of boot sole compatibility: You can wear your tech boots to seek out remote powder stashes (a pin toe is required for uphill travel) or strap in your alpine boots for a day at the resort. They’re heavier than tech bindings (the Shift is almost 1820g, while the Duke PT clocks in close to 2300g), but they’re the least compromised option for skiers who split their time between the front and backcountry and want to use the same setup in both environments.
 

Backcountry Ski Boot Soles

The ski boot sole discussion is actually a continuation of the binding compatibility dialogue above. In other words, the boot sole is another determining factor of what bindings will fit your boot. This certainly is one of the more complicated topics surrounding backcountry ski boots, especially as technology continues to change so dramatically—hence our decision to put together a boot and binding compatibility guide. That said, it's very important to have a general understanding here and, at the least, have the wherewithal to check that your boots and bindings are compatible before you buy. 

Let's start simply: An alpine (resort) ski boot sole (referred to as ISO 5355) is flat on the bottom and only compatible with corresponding ISO 5355-ready bindings (often frame style). A touring boot sole (ISO 9523) is rockered (similar to the bottom of a boat) to allow for a more natural gait. It also has sticky rubber on the bottom, which comes in handy for walking or kicking steps in snow. These boots, such as the Atomic Backland Carbon, are only compatible with tech bindings.
 

Now there is a third option. In the last few years, Salomon and Marker have created new technologies—Walk-to-Ride (WTR) and GripWalk (GW)—that allow a boot to be compatible with both frame bindings and tech bindings. Boots with WTR or GripWalk technology are not quite as rockered as tech-only boots, yet not totally flat like an alpine boot. Most of these boots are made with tech fittings as well. Many other companies have followed suit, leading to popular boots such as the Atomic Hawx Ultra XTD, which can be used with tech bindings, tech toe/alpine heel bindings, GripWalk frame bindings, and MNC bindings (see below). Thus, one pair of boots can now be used with multiple ski setups (resort setup, alpine touring setup, etc.) without the pain of swapping out bindings or having incompatible combinations. 

It's important to note that not all alpine (non-touring) bindings are WTR or GripWalk compatible. If you are interested in using your backcountry boots with your downhill setup, it's definitely worth double-checking whether or not your bindings are WTR or GripWalk certified. Furthermore, new MNC (Multi Norm Compatible) bindings from Marker and Salomon take away the guesswork—they simply are compatible with pretty much every style of boot. Very few boots and bindings are labeled MNC (Salomon’s S/Lab Shift2 MN binding is one standout), but it is a strong indication of where the market is headed.
 

Choosing Skis and Bindings

When choosing a pair of boots, it's important to think through the style and performance level of your entire ski kit, including your skis and bindings. Starting with alpine touring skis, you'll want to make sure to match the flex of your boots with the stiffness of your skis. There is no rubric for this, but generally, boots with a higher flex rating (115+) should be paired with stiffer skis, and vice versa for boots with a lower flex rating. A pair of soft skis can feel overpowered by a stiff boot like the Maestrale RS, which can lead to a disconnected and insecure feeling while descending. Alternatively, it is never fun to feel as if you can't turn your skis while using a pair of boots that flex too much.
 

In addition, your ski bindings play a key role in performance. Like boots, the binding options fall into general categories of lightweight, all-around, and downhill-focused. Light and fast travelers will want a minimalist design like the Dynafit Superlite 175. The Salomon MTN Pure is an excellent all-rounder option, and the Salomon S/Lab Shift MNC has a lot of appeal for those splitting time between the resort and backcountry. Most importantly, as we covered in detail above, you'll want to make sure your boots and bindings are compatible with one another.
