  Size Chart

At the same time and place every year, the boot wizards at SCARPA emerge from their R&D dungeons to see how their creations are being used. It was during such an emergence they noticed the F1 LT being pushed farther and harder than ever anticipated. With ideas in their heads for the next best thing, they retreated back from whence they emerged, spending the next year testing different brews of boots until finally, they emerged with the F1 XT.

Losing none of the mountaineering chops that made the LT an instant hit but gaining the progressivity found in many heavier options, the F1 XT is a boot that seriously excels in many areas. Keeping the generous 72° range of motion of its siblings, the XT is no slouch on the skin track. The stiff 3D Lambda Torsion Frame technology on the lower combined with the Carbon Grilamid cuff ensures confident and precise performance. Notably, no carbon in the lower means that this boot can be punched and adjusted, unlike the F1 LT, so even the gnarliest bunions can be accommodated. Finally, SCARPA opted for a cuff/instep bucke and burly cam-lock power strap for maximum durability.

If you can’t decide if you’re here for speed touring, mountaineering, or pushing the descent, the F1 XT will fit the bill perfectly.

  • Buckles and a cam-lock power strap are stout and durable, especially within this category.
  • Race-ready 72° range of motion allows for efficient climbing.
  • Simple and clean Speed Lock LT ski/walk mechanism minimizes ice buildup and allows for adjustable forward lean between 11°, 13°, and 15°.
  • Optional rear spoiler can further adjust forward lean by ± 2°.
  • Grilamid FG LFT lower helps provide a progressive flex and is punchable if need be.
  • Moldable liner from Intuition allows for a truly customized fit.
  • RECCO helps with search and rescue efforts should you take the wrong turn.
  • Italian ancestry.

Question from Phil
 
I'm wavering between the F1 XT and the F1 LT.
The lower weight of the LT is not the deciding factor for me, what is more important to me is good downhill performance.

Which boot offers better downhill performance?

Is the XT slightly warmer than the LT? (different liner)
Is the XT slightly more durable than the LT?
1/12/2025
Answer from Carlos M
 
Hi Phil,

I would put durability and warmth approximately equal between the two boots!

If you are after the better downhill boot, I think the XT is better for most. It is not hugely different, but the cuff and shell buckles are more downhill-oriented, and the powerstrap is beefier. The forward flex is also a bit more progressive in the XT compared to the LT, which is more of a wall. Some people prefer the wall-like flex of the LT, but I think most would get along more naturally with the XT.

Question from Allison
 
Hi there-

I have the Tecnica Zero G Guide Pro Ski Boots - Women's 2018 in size 24.5. What size should I go with 24 or 25? I live far away from a ski shop that has these boots or else I’d try them on.

Thank you as always!
12/27/2024
Answer from jbo
 
Hi Allison, you would most likely be a 25 in these. With SCARPA, the 24.5 & 25 are the same size shell. Unless you have a loose/comfort fit currently, then you might be able to size down to 24.

I bought these boots last season, and since, they have become the most frequently-skied boot in my quiver. I use them with a variety of skis ranging from 76mm underfoot to my Alp Tracks 106 on powder days. They have been the best-fitting boot I've owned for my moderately narrow feet, and have delivered plenty of comfort and great performance over many long days in the backcountry.

They don't walk quite as well as a race boot, and they don't ski quite as well as a four-buckle boot, but they do both well enough that I find myself grabbing them on most ski days. I feel confident skiing them fast and aggressively as long as the conditions are decent, and they have held up to plenty of small airs and side-hits as well as a fair amount of hiking on rocky trails. Overall, after about 60 days of pretty hard use in a variety of conditions, they are still in great shape with no concerning wear on the gaiters, no play in the cuff pivots, and only the usual cosmetic wear on the shells and outsoles. The liners have been excellent, and when they wear out I will try to replace them with the same stock liner, if available. I expect to get a lot more life out of these, and will probably buy another pair when they die.

Hi there! I have a Lt boots, that i use with an atk bindings for my 95 freeride set
Since i bought a new all mountain (85)more resort oriented skis with a griffons, could i use the LT with them since are multinorm binding? I know the Lt are not gripwalk, that will be easier, but if not any other binding non tech that could use this boots
Thanks a lot
12/7/2024
Answer from Carlos M
 
Hi Gabriel,

Unfortunately this boot will not be compatible with an alpine binding, even an MNC alpine binding - this is a "tech only" boot, which means that the toe and heel lugs are not designed to interface with an alpine binding system. You may be able to put it in there, but it would not be recommended or safe.

MNC bindings can be used with GripWalk or ISO 9523-rated touring soles, but many lightweight boots do not conform to any standard other than tech.

Question from Alex
 
How would you compare these to the lighter Kilo and conversely the more comparable in weight Solar II as a daily driver in mixed conditions?

In terms of downhill performance only for a ski around 1100-1200g/ski for an intermediate skier. Worried about stiffness and seeking fun!
11/22/2024
Answer from Carlos M
 
Hi Alex,

Fit-wise, they are different! The Kilo and the Solar have roomier lasts width-wise, although they are different shapes, and the Solar has a bit lower instep. Fit is very important, so you'll want to choose the one that fits you best. If you'd like to go more in-depth with fit, please email us at help@skimo.co and we can help!

In terms of downhill performance, the F1 XT and the Solar will be stiffer than the Kilo and can be pushed a bit harder. The Kilo will walk the best, and is the lightest in the group.

THESE BOOTS SUCK!!!

I bought a pair of these in Europe last season before they were available in the US. Typical euros...so pretentious!

Look bro, they only have 2 buckles. I've seen you huck those cliffs man...and anything short of 5 buckles just won't handle your awesomeness.

And no way latex skimo dude...they are way too heavy for you, monsieur. You deserve 100% French carbon fiber for your petite feet.

Like I said: don't buy these boots. Especially if you wear a size 30.0. I'm going to do the world a favor by buying another pair for next year so you don't have to.

In summary: These boots suck! 5-Star

Question from Adam K
 
I currently have the Tecnica Zero G Peak Carbon for bigger days and ski mountaineering. I love them on the uphill but they don't ski as well as I would like. How would you compare the downhill performance of the Tecnicas to the Scapra F1 XT?
5/2/2024
Answer from Carlos M
 
Hi Adam,

The F1 XT is a bit damper and more progressive feeling than the Peak, but not a lot. They're both lightweight, tongueless boots. The bigger difference would be the fit, which is narrower and lower volume on the F1 XT than the Peak. It is very likely that one will fit you much better than the other, and the one that fits better will be the one that skis better.

Question from Alex
 
How much does this forefoot buckle (vs the BOA on the F1 LT) improve the fit for lower volume feet? I have found that the F1 LT did not fit my foot due to my low volume. The Skorpius fits my foot better, but I'm interested in the weight and ROM of this boot. I can't find this boot anywhere to try on, so I'm trying to figure out how manageable this could be for a lower volume foot.
4/12/2024
Answer from Carlos M
 
Hi Alex,

I actually purchased the F1 XT over the F1 LT pretty much entirely due to the buckle over the lower shell (I did not get along well with the Boa). I felt that the Boa was not doing a good enough job securing my lower-volume foot, and when I cranked it down tight enough, it was uncomfortable. Of course, buying a new boot always has a little bit of uncertainly, but so far, I have about 15 days on the boots and I'm very happy with my choice. Heel hold and comfort have been excellent and I like the security and durability of the buckles.

The Skorpius is a significantly stronger boot on the downhill, but the XT will walk a little bit better (just a little - the Skorpius isn't bad at all when you open up the cuff). There isn't a huge amount of weight between them, honestly, so I would personally go with the one that fits better. For me, the Skorpius was too wide in the forefoot, and slightly low in the instep.

Overall, I do think the XT will work better than the LT for lower-volume feet, especially with the right footbed.

Question from Nico
 
How does this boot compare to the Atomic Backland Carbon?
The Atomic seems a bit soft when skiing, but it could be me.

I have always used the Atomic Backland 85 + Atomic Backland binding.
Recently, I bought the Hagan Boost 94 Pow + ATK Raider 13 EVO.

Will the Atomic be strong enough? How does the Scarpa F1 XT compare to this?

My weight is 65kg and I am about 178cm and charge soft to semi rigid (so not hard).
3/17/2024
Answer from Carlos M
 
Hi Nico,

These flex stiffer than the Backland Carbon, but are in the same general weight and performance category. They are a bit lower volume over the instep than the Backland Carbon. Either one would be okay with that ski, although you may be able to get more out of it with a beefier boot. It all depends on preference and whether you want to optimize more for the downhill or uphill. If you were to buy a new boot with the intention of getting significantly higher overall downhill performance than the Backland, I would consider something a bit beefier than the F1 XT. But if you just want a bit more stiffness, they will give you that.

Question from Mark T
 
Hello, I came into a set of K2 Mindbender 108 skis in new condition. I ride chairs some but also go into the BC often. I’m thinking of setting the new skis up with ATK Raider 12 bindings and buying a set of Scarpa F1 XT boots from you guys to use with them, based on advice from a friend about setting up a versatile kit useful in or out of bounds. I currently use Atomic Hawx 120 Ultra XTD boots with some Blizzard Zero G 95 skis and G3 Ion 12 bindings for this kind of activity. I only weigh about 145 lbs and am 5’-8-1/2” so not big, but I ski somewhat aggressively. The Atomic boots are a bit uncomfortable on long tours due to a pressure point on my bony instep, so I’m hoping the F1 XTs would be more comfortable. What do you think of that proposed new combination (Mindbender 108 Ti, ATK Raider 12, Scarpa F1 XT)?
3/7/2024
Answer from Carlos M
 
Hi Mark,

Congrats on the new skis! I would not recommend the F1 XT for the sort of skiing you're thinking of, unfortunately. It is a lightweight, race-plus style touring boot that is best suited to lighter skis and longer days in the backcountry. I do not think it would be satisfying or durable enough for aggressive resort skiing, especially with a 108mm resort ski. It is an awesome boot, but not designed for that kind of use.

My recommendation, if you are looking for new touring boots, is to fill out our  boot fitter , and we can help guide you toward a pair that will fit you and suit your needs.

Answer from Mark T
 
Hello Carlos, thanks for the reply. As mentioned I’ve got a high instep, actually a kind of bony, possibly arthritic bump at the tarsal/ metatarsal joint on both feet. Local shops’ staff in Flagstaff, AZ have told me a need a high volume boot, but there are limited options for trying on boots locally due to their focus on alpine skiing gear, not AT. I tried on the Scarpa Alien recently and it didn’t feel much better than the Atomic Hawx Ultra HD 120s I’ve been using, but with some pain points especially on a long day. Are there boots you might be able to recommend I try, that would be stout enough to drive the Mindbenders, but not TOO heavy for a relatively light / small skier like me to use for hike-to off piste, and BC excursions? Thanks for any advice you can provide!
3/16/2024
Answer from Carlos M
 
Hi Mark,

The Dynafit Tigard is a high-volume, medium-width boot with lots of room over the instep. It is one of the best options for a high-performing resort-capable touring boot, if it fits you. It is beefy enough to stand up to regular resort usage, but it does have a good enough walk mode to be reasonable to hike in and take for shorter tours. Could be worth trying on!

Question from Dan P
 
Hello, can you compare the downhill performance of this and the original F1? I assume the original skis better, but I'm weary of the velcro strap/buckle combo. Thanks.
2/19/2024
Answer from Niko M
 
Hi Dan, the F1 is a burlier boot that skis with some more stability. The main difference in design is that the F1 has a tongue, whereas the F1 XT is tongueless. That said the F1 XT does have a rather progressive and supportive flex, so it skis pretty well compared to other similarly constructed touring boots. Do note that the F1 and F1 XT / LT / GT have different interior shapes and fits. Please feel free to reach out to us at help@skimo.co for more details!

Question from jimmy willy
 
My Alien RSs, which I love, are size 26. My Scarpa Maestrale RSs, which I'm ambivalent about, are size 25. I'd say they both fit about the same and I'm more or less happy with the fit of both, despite the diff sizes among the same manufacturer.
The question is, do I order a 25 or 26 in F1 XT?
2/16/2024
Answer from Niko M
 
Hi Jimmy! The F1 XT and Alien RS share a very similar lower shell and therefor a similar fit. If you found the Alien RS in a 26 to fit well, you can expect the same in a F1 XT in a 26 shell size. Thanks!

Would you recommend going all the way to a size 25 if you wanted the fit of a 24.5?
1/15/2024
Answer from Carlos M
 
Hi Jake,

24.5 and 25 Scarpa shells are the same, so yes, if you wanted to get close to the fit of a 24.5 from another manufacturer, the 25 Scarpa would be the closest. It will be very slightly roomier than a 24/24.5 from a brand that does not use Scarpa sizing.

Why arent there half sizes?
Ive been using a 24 F1LT and love it but wanted to go a bit bigger to have the option to add a warmer liner for higher altitude missions.
Was hoping to go up to a 24.5. Would that be the same shell size as the 25?
1/13/2024
Answer from jbo
 
Hi Jake, like the alpine companies, SCARPA didn't bother with half sizes since there is no difference after a heat mold anyhow. Yes a 24.5 and 25 would be the same in SCARPAville.

Question from carl
 
Does this XT get close to the downhill performance of the original Skorpius? Or still in a slightly different class?
12/4/2023
Answer from Carlos M
 
Hi Carl,

I would say they're still in a different class. The Skorpius is more in the class of the original F1, which is a step up from the XT. But I would say the Skorpius is even stiffer than the F1. The tongue makes a big difference, as well as whatever magic they worked to get the Skorpius to feel so solid. The XT is a great skiing boot in its class of tongueless, race-plus touring boots, but the Skorpius is a step up.

Question from Tony
 
Can you guys recommend an aftermarket gaiter that would work for this boot? As abc noted in their review above, the gaiters on these are shredded after (during) their first season, and I’m about to cut off the tattered remnants of mine.

I’ve had hundreds of days on both the F1LT and the Alien RS and wore a few holes through those gaiters fairly quickly, but although the XT gaiters look burlier (and probably add to the weight) the new gaiters durability sucks in comparison to their lighter predecessors.

It’s a shame because they skin and ski great.
11/13/2023
Answer from Julian K
 
Hi Tony, we are sorry to hear this! An option could be to use a hiking gaiter and attach it to the buckle cable at the forefoot, then wrap it around your liner and ankle with the grilamid cuff folded back and then fasten the upper buckle over the top to secure the rig. Hope this helps!

I probably have almost 100 bc days spread over two pairs of these boots (tried downsizing halfway through the season). I don't have a ton of experience but I skied these a lot.

- the gators are pretty much destroyed on both pairs. Pretty standard for this sort of boot but I'm guessing they're less durable than the f1 lt gators. Maybe because they bunch up under the buckle and rip.
- the sole got torn up on the first rock scramble. Again pretty standard, though I'm skeptical of light colored rubber
- I mostly skied without the power strap, it feels too stiff. This should give you a good idea of my style of skiing.
- I think the flex feels a bit more forgiving than the f1 lts and the toe buckle is more secure but less useful on the uphill. I'm not sure this is a good thing. I also think mine tend to have a bit less play in the lock mechanism.
- I got one pair punched for my tailor bunyon but they were only comfortable doing a few mm. This isn't quite enough, and is my main problem with these boots. The tech wasn't convinced that the fiberglass reinforced shell is actually more forgiving than the carbon on on the lts. But maybe it won't crack at the hinge like the lts
- I've skied them back to back with the zg peak carbon. The peak clearly had more lateral stiffness, I think the flex on the XTs is nicer and they ski like a slightly heavier boot ( which they are). Size wise the 27.5 peak is about right in the middle of the 27 and 28 scarpas.
- the black shells suck under summer California sun
4/29/2024
Reply from Abc
 
Following up on this: once the gators are destroyed, the hard plastic reinforcements flop around and dig into and destroy the liner. This isn't great since the boots are already a bit high volume above my foot

I also managed to get some extra space around my toes by dremeling off a bit of the rubber bootboard. The bootboards in mine curled upwards near the toes and were higher than the bottom of the boot. Super easy mod and relieved pressure on the tops of my toenails.

Answer from Carlos M
 
Hi Ian,

You could, and people certainly do, but we wouldn't necessarily recommend it for most skiers/conditions. It would work in powder! But if conditions got less than ideal, you would be very aware that you're in an 1100 gram boot. It would be very much at the limit of the boot.
10/28/2023
Answer from jbo
 
Hi Ian, for an alternate viewpoint, I think that combo works great! Seeing as how you would/should only be skiing powder on those 112s, that boot will let you soak up a ton of it.
