What do you get when you merge an Alien with a Maestrale, a race boot with a beef boot, an extraterrestrial with a cold northwesterly wind? You get an F1 race car, er, two-buckle touring boot! As Scarpa's signature backcountry touring boot, the F1 sits at the crossroads of out-of-this-world uphill speed and deep-powder charging on high-fat skis. The hinged Evo tongue on the F1 allows for excellent ankle range-of-motion on steeper skintracks and flatter slogs alike, while the high cuff and power-strap-based design means you'll blast down steep lines without reservation. To create that coveted power-to-weight ratio, the designers borrowed Alien technology by inserting carbon fiber into the lower shell in a splayed pattern that transfers power directly from your leg to the ski. A Grilamid cuff provides plentiful support when skiing in the front-seat and a scooped rear design means a turn in the back-seat won't end in a crash. The boot's lower is held together with a BOA system that cinches a generous 102mm last for just the right forefoot fit.

  • Carbon Core Tech is fiber-reinforced nylon that makes the lower shell more rigid.
  • Fast Buckle works in conjunction with a burly Velcro strap for simple and secure cuff.
  • Alien style Boa® lacing system in the lower shell lets you dial in the perfect fit.
  • SCARPA Intuition® liners (221g [27]) are heat moldable and preloaded with flex zones.
  • Evo tongue is designed to flex with your leg and can be topped up with a power strap (+26g).
  • UFO EVO soles are the latest in durable grip from the Vibram® family of overachievers.
  • 62 degree range of motion is what your ankles would demand if they could talk.
  • Dynafit Quick Insert fittings help make stepping into tech bindings a treat.
  • Two forward lean settings let you tune your stance to match your style.

Update 2018/19: The iconic Scarpa F1 is still ahead of its time but in order to keep everyone happy with shiny boots, an updated paint job was brought to the table along with some Recco hardware in the power strap.

Update 2020/21: The Scarpa F1 has received a fabulous look for the 2021 year. Additionally, the F1 now has a small plastic extension on the lateral side of the lower shell to help guide the tongue over top, preventing it from occasionally snagging underneath when you don the boots.

Questions & Reviews

Question from Ben Nosarzewski
I enjoyed touring in the Scarpa F1 boots except that the cuff felt very upright on the descent. It appears that the forward lean of the boot should be adjustable by flipping the orientation of the piece that the rear latch locks onto (as described in this video from Scarpa:

Unfortunately I tried following the video but I cannot figure out how to remove that piece in the rear. On both boots, the screw loosened but just keeps turning without coming out. I tried prying the part off but it won't come out. Now I cannot even tighten the screws again (they just turn without seeming to catch onto any thread). Very frustrating.
Answer from Jeff
Ben, Did you pull the liners out and look at the nut on the inside? It may be spinning and need to be held in place. If striped, we have new parts.
Answer from Benjamin N
Thanks for the help. I pulled out the liners and just held the nut in place with my finger to remove the screw. Pretty obvious but it wasn't mentioned or shown in Scarpa's video tutorial.

Question from Joe
Hey, these boots fit me great but wondering how these fit in the F1 line (F1, LT, GT, XT) in terms of stiffness? I ski a 112mm underfoot and tend drive the front of boots so want to make sure this can stand up. Would be a daily driver so not just powder conditions. Thanks!
Answer from Emmett I

These are the stiffest, most downhill-oriented of the F1 line. In powder, they will be just fine. In crud and variable snow, it depends on your skiing style. If you want, reach out to us at and we can go more in-depth.

Question from Mike
Hi I’m looking for more of a ski mountaineering boot but I’m on 110 waist skis. Would this boot be a good option ? I was also looking at the xt and the mtn summit but unsure how they would drive a 110 waist ski (Draco freebird) ? Let me know you thoughts and
Answer from Emmett I

Reach out to us at and we can go more in-depth!

In powder, you'd have no issues skiing a 110 with the F1, or XT and MTN Summit for that matter. In firmer/variable snow and/or high speeds, you might have more issues. The F1 would be fine for an all-around touring setup with the 110, but I wouldn't go much lighter than that unless it's a dedicated powder setup.

Question from Daniel
Hi! What's the best bet in terms of sizing for a 27cm foot?
Obviously looking for a trouble free yet well skiing fit. Atm I tour in older 27.5 306BSL Dynafits.
Answer from Carlos M
Hi Daniel,

Generally, for a foot that's 270mm on the dot we would put you in the 26.5/27 shell. However, it does also depend on the overall volume of your foot and whether the F1 would be a good fit for you in the first place. To delve deeper into fit, we recommend filling out our online Boot Fitter!

Question from Mariusz W
Can the shell be punched in toe area? I have a feeling like I need bit more space in height in the toebox. Or maybe grinding the boot board is other option?
Answer from Julian K
Hi Mariusz, the shell can be punched in the toe area. Another option to try out would be to add a footbed. That could help draw the toes back from the front of the boot.

Excellent boots, in my second pair as of this writing. Great balance of weight, ankle mobility while walking up and downhill performance for skiing. A great first choice for anyone looking to step into a lighter setup without comprising too much downhill performance. Not giving 5 stars because, well, could always be lighter ;).

Question from Jordan
Can these drive a bigger ski (100mm 1500g) than F1LT? Or the new F1XT?

LT/XT are listed as stiffer, but these are beefier + tongue so I'd imagine they inherently ski better
Answer from Zak M
Hey Jordan, I would say the F1 is a bit of a beefier boot with a more "progressive" flex than the F1 LT. So yes, your thoughts are sounds, and for some slightly wider and heavier skis, I would choose the F1 as being the stronger skiing boot out of those three. Thanks

Question from Clare
Hi, Im thinking about the F1 I have a wide forefoot and high instep size 24 currently have the Scott celeste but don't like the range of motion and find them too lose. Just have a new set up of camox freebird and ATK C-raiders, looking for something light to match and works with my annoying feet.
Answer from Jeremy L
Thanks for reaching out, Clare. Not so sure the F1 will have the width you're looking for in the forefoot. If you'd like to fill out our online boot fitter we'd be happy to help.
Answer this question:

EG1 (downright abused product)
Bomber boot. I find these to be the best touring boot when it comes to uphill/downhill performance I have ever used. I have been on Maestrale's, Lange XT 130's and spent a past life in plug race boots - so I think my opinion is quite balanced.

Some thoughts:
- The LT's (which I also have tried) give up a lot when comes to skiability. I would go with the classic F1's, personally.
- Some people seem to remove the top strap (liner focused). I find this to be a "must keep" as you can really get good purchase on the top of the cuff which helps when its bumpy.
- Think the boot skis best in the "+" position on the flip switch - personal preference but think the forward lean helps given the static nature of the walk mode lock mechanism (like all Scarpa's)
- Much easier on/off than the Maestrale

Recently spent a week living in these boots while skiing the Haute Route. I noticed that others (specifically in Maestrale's and other boots without a BOA) suffered from the issue of having the boot be too loose when in walk mode and therefore destroying the foot with blisters. The BOA system and top strap here are great to eliminate that issue as they allow you to get full ROM when in walk mode, but also keep the foot tight in the liner to avoid issues from rubbing.

The only thing I dislike (which is SO minor), is that when you take the liners out to dry you have to be careful not to push down the interior plastic protector/sealing around the walk lever when you put the liners back in. I accidentally have pushed it down a few times, and you quickly wonder why your heel is in pain. Luckily, an easy thing to be mindful of and does not hurt the boot. Just can add a minute of annoyance at the trail head.

Finally - and most importantly - these ski really well, especially when paired with an equally light and touring focused ski. I think when skied with a beefier ski, the boot struggles to keep up - but when the pairing is in the same weight class, it's a dream.

I wish you could replace the grip walk - as these boots beg you to keep them on to the point where the soles wear before you're ready to get new boots...

Question from Don
Upgrading some Dynafit Ones. I am looking for weight savings but also gains in performance as boot technology has probably improved. How do these compare in downhill performance?
Answer from Patrick C

Great to hear from you! I would agree with you, a few years have passed since that boot hit the market and touring gear has seen some upgrades. My suggestion would be to check out our Bootfitter to see what boot may work best. I have not skied the Dynafit One myself, but I would venture a guess that the F1 would be a solid step in the right direction when it comes to downhill performance. Hope this helps!

Question from Raquel
Hi - Do you need to size up and by how much on these boots compared to alpine resort boots? I'm a 24.5 in Lange XT3's that I used for resort skiing. I'd be using these for skimo, training for skimo race, and skimo race.
Answer from Julieana
Hey Raquel,
We generally don't suggest sizing up your touring boots unless you opt for an extremely snug "performance fit" in your alpine boots. Unless you find your Lange XT3s to be exceptionally snug, a 24.5 will still likely be an appropriate size for you in touring boots as well. Feel free to email us at if you'd like to get further into the details of sizing and fit!
Answer this question:

Eddy v (used product regularly)
I got a pair of F1s for a trip to Denali after demoing them for a day. Coming from a resort setup and a pair of Maestrale RSs, I was initially skeptical that they would ski well enough, but they blew me out of the water with how well they skied for this light of a boot.

Obviously the walk mode is much better than the Maestrale (even after replacing the liner with a thicker Intuition liner for the cold), and the weight loss isn't huge but is noticeable. Ski mode is a significant step down from the Maestrale RS, but the boots are still fairly stiff. I'd say the bigger difference in ski mode is that they have less of a progressive feel to the flex. I only skied these on lighter skis in more mountaineering settings, so it's hard to judge how they'd drive a heavier ski at higher speeds, but overall I was pleasantly surprised.

My only big complaint with these boots is the buckle - opening it up doesn't give you enough ROM to tour properly, so I have to undo the velcro each time I transition (and then refind the correct tightness after).

While I like the F1s, looking back, I probably should've gone for an F1 LT instead - it seems like you don't give up a ton in ski performance, but you gain a LOT in walk performance, which has become more and more important to me over time.

Question from john
Perhaps this is obvious but... since the shell size is the same for half sizes (25.5 shell = 26 shell) and the liner makes the difference, is it generally agreed that the half sizes run warmer?
Answer from Tristan M
Hi John,

After a heat mold of the liner and or some skiing, the 25.5/26.0 sizes will be indiscernible. I would treat the half sizes within the same shell size as the same boot.

Question from Dario
Hi, everybody.
Do you think the F1 would be a good boot to use on a stiffer touring ski with good downhill performance, such as Salomon MTN 85 or Stöckli Edge 88?

Second question: My foot is 26 cm measured. After trying them in a shop, I ended up buying a 27, since the 26.5 was feeling too tight. Now I have the impression that my heel is able to move a bit too much while walking.
Do you think a 26.5 would have been better? Is there a way to solve this problem without changing boot?

Thanks a lot!
Answer from Julieana
Hey Dario,
I think the F1 would be a great boot for either of those skis!
As far as sizing, for Scarpa boots, the shell size is exactly the same in the 26.5 and the 27.0. Any differences you felt initially would have just been differences in the liner that would eventually pack out the same. If you aren't experiencing blisters and your heel is locked in when you're skiing downhill the fit is probably fine, but if you do think there's too much room and you want to size down a shell size, you'll want to go with the 26.0. If you need any more information on boot sizing feel free to email us at and we'd be happy to go more in-depth with you!
Answer this question:

Question from Tom
My shell size would be 30.5/31 - I have a long, but low volume foot. Would it be better to order the 30.5 and then adjust with the liner? I suppose the size difference is achieved with e different/thicker liner?
Answer from Cole P
Hey Tom, there is a couple of ways to achieve a tighter fit. Going with the 30.5 size is a great start, in addition to that adding a nice after-market insole to help take up some volume. You can also add a boot shim to take up even more volume. you can purchase boot shims here. A thicker liner would achieve the same goal. I do suggest looking at other boots that have less volume like the La Sportiva Skorpius CR boot. You can always try our online boot fitter by going here.

How does this new version compare to the previous one (2018/2019, the one that was released as F80)? Is it just a different paintjob or are the features/specs in any way? Thank you!

There is more than a paint job this season .. The tongue and interface of it on the shell have been cleaned up and refined. But otherwise the same.

Question from sabby
Are the newest version F1 punchable in 6th toe and accessory navicular areas? Thanks!
Answer from Julieana
Hey Sabby, the F1 is totally punchable in those areas! However, if you're thinking of the new F1 LT Boot, any punching done to that boot would void the warranty so that model is technically not punchable.

These boots were comfortable right out of the box. They're lightweight but ski great. I have about 75 days on them and have had no issues. Definitely recommend.

Centerfold (downright abused product)
I really loved my Scarpa F1s. By far the most comfortable boot I have ever worn. I was drawn to these because many of the Utah Avy crew recommend this boot. And I can see why.

They are very stiff boot. Not quite as stiff as the Maestrale but for most of my type of riding it was plenty stiff (30 degrees or less for me most of the time). The range of motion is amazing. It feels like you are in a tennis shoe at times.

I really ended up liking the boa in the front.

My only complaint, and this isn't a real complaint, is that I have straps needed to get replaced after a couple seasons. Not a big deal but another cost to be aware of.

I also gave this boot a 4/5 out of 5 because after 2.5 seasons I upgraded to the F1 LT. If you can fit those I would go that direction. Otherwise, these are a great choice.

Alex (downright abused product)
The F1 is the best all around touring boot I've used. Ive been through a couple pairs and it splits the Maestrale and Alien/F1 LT beautifully. For a great price you get a boot that you can ski pretty much any AT ski with and its light enough for long distance adventures or a daily driver boot. I ditched the top power strap to make transitions more efficient and it still drives a 105 wasted ski with ease.
