I have a high instep, subsequently because of the boot design a tad difficult to put on. However, the fit is incredible. They are the best skiing boots I’ve ever had
SCARPA F1 LT Boot
Sometimes, when two things are combined, they produce something far greater than the original constituents. History is marked by such fusions: fire and meat, iron and carbon into steel, ski poles and ice axes, J-Lo and Shakira. Now, two of the best options for backcountry boots have joined forces to form the all-new, all-powerful F1 LT. By combining lightweight race features from the immensely popular Alien RS with the time-tested durable and reliable F1, SCARPA has created a boot that will change the game for years to come. While some boots may walk the line between race boot and touring boot, the F1 LT is the line. Built for long and fast tours as well as deep, technical descents, this is the boot for skiers who want to chase the most ambitious of objectives while spitting at the notion that skiability and weight are trade-offs.
The lower of the F1 LT was inspired by the Alien RS: made with a Carbon Grilamid LFT shell that is built with the same 3D Lambda Torsion Frame used by the RS to provide more direct power from your foot to the ski, the lower is secured by a simple Boa dial that cinches the waterproof gaiter across the top of your foot providing a quick, dry, and secure fit. Strategic cutouts on the exterior eliminate excess weight and material wherever possible while maintaining enough structural rigidity to drive high-fat skis with ease and confidence. The cuff (also made of the same Carbon Grilamid LFT) trades out the cord-closure of the RS for an F1 buckle strap to increase power and reliability and an additional removable powerstrap (+30g) for even more control on the descent. The spring-loaded ski-walk mechanism is easy to flip and provides an incredible amount of low-friction articulation that will make sure these boots are the last thing to hold you back when speeding uphill. The F1 LT is the boot that will make freeride skiers want to race and make racers want to freeride. Plus, a sexy orange-black paint job will give your ski partners something to look at as you fly past them in your new SCARPA F1 LT's.
- The prodigal child of two of SCARPA's most popular boots, the F1 LT sets the bar for other hybrid race/touring boots.
- Ankles rejoice! 72° degrees of motion is a 10° improvement over the F1 and is more akin to that of race boots.
- Carbon Grilamid LFT construction ensures the highest possible power-to-weight ratio.
- 3D Lambda Torsion Frame increases direct power transmission from foot to ski.
- Boa-secured waterproof gaiter will keep your feet cozy and dry.
- Dynafit Quick Insert tech fittings make stepping in a breeze.
- A surprisingly powerful race boot, or an impressively light touring daily driver, this boot can and will do it all.
- Forward lean can be adjusted by moving the ski/walk lever mounting position, with choices of 9°, 11°, or 13°.
- Removable rigid spoiler on the back of the liner is attached with Velcro so you can further tweak the forward lean (+/- 2°).
- Included power strap (+30 grams) pops on and off in a snap.

Hey Matt, there is a lot more lateral rigidity and structure in the F1 so it will be much better suited to wider skis.

i'm seeing that scarpa is traditionally narrow... which is weird because i have wide feet and traditionally only fit well in scarpa ice climbing boots. i was told that the f1lt is wider than the alien rs by a bit. care to confirm or deny this?
also, how much wider is the comparable dynafit boot (and which boot would that be?)

Hey John, the F1 LT has the same exact lower shell shape as the Alien RS, the difference is solely in the cuff, so it will fit just the same as the Alien RS--which is quite narrow. There isn't a Dynafit comparison to this boot. Some comparable boots that are wider are the Dabello Quantum Asolo Factory Boot or the Fischer Travers CS Boot.
11/27/2020
Julieana, there are two responses below (from a customer and from skimo's Jeff) that indicate that the F1 LT may fit a bit wider than the Alien RS.
See Brandon's comments in his 10/30/20 review and Jeff's comments in his 7/10/20 response. Apparently, they fit differently because Scarpa lowered the height of the footboard in the F1 LT.
Could you please clarify this? I think a lot of us that found the Alien RS a bit too narrow are interested in this issue. Thanks!

Hi Andy, the F1 LT comes from the same mold and is not materially different in width. We've had some internal debate, and some of us feel like it's a touch wider out of the box due to the liner and/or positioning. My foot couldn't tell any difference between it and my Alien RS that has been well skied (and liners replaced once). With a custom fit in our shop, there would be no difference.
11/27/2020
I just received a pair and while they feel a touch wider in the metatarsal area than the Alien RS, it’s not a huge difference. What is noticeable is additional vertical/instep volume. Compared to my Alien RS with packed out liners that have over 100 days on them, I need additional underfoot shimming with the F1 LT and brand new liners.
11/27/2020
I should have added that it’s not clear whether this added volume is from a thinner bootboard in the shell or from changes with the liner. Since the liner seems a little burlier than the RS liner, I’d guess it’s the former.
12/2/2020
Quick note on fit/fitting on the F1 LT from a diehard Alien RS-wearer. While the lower shell/scaffo of the F1 LT is not "materially different" from the scaffo mold of the Alien RS (cf. Borro, 2020), there seem to be distinct differences in the overall fit of the F1 LT that, I think, will make it an attractive option to skiers for whom the Alien RS was just a fraction too narrow in the mid-/fore-foot. One, the Boa configuration on the LT sits higher and farther back on the instep than the RS boa did, and the plastic spreader plate that holds the metal tensioning wire is ~5mm wider on each side -- distributing pressure more evenly across the top of the foot/instep. In turn, the heel is held "back" in the boot rather than just "down" in the shell. Second -- and I think this might be the aspect of the boot we all missed in the hubbub around its release -- the heel platform on the LT is noticeably elevated relative to the forefoot, which confused me at first until I noticed this random line in Scarpa's web copy: "New Zeppa increases ramp angle by 3.5 degrees." ["Zeppa," aka, boot board, or more literally, "a wedge-shaped piece of wood, borrowed from Lombardic 'zippa,' a late borrowing from Latin 'cippus.'" (OED)]
That added Zeppa ramp angle increases the pressure on the instep/Boa, lessens the pressure on the forefoot, and allows the metatarsals/toes to spread out in the boot without cramming against the front. (Granted, measuring the Zeppa-induced ramp in degrees rather than millimeters is a little confusing, since it would lessen with the bigger sizes and increase with the smaller sizes, so other folks may have a totally different fit impression of the Zeppa, or may not notice it at all.) Right out of the box, the 30.0 LT feels like a 31.0 RS, which is more of a "comfort fit" for me; I can fit a blue Superfeet insole in the 30.0 LT, which I never could have done in the 30.0 RS without crushing my big toe and 5th metatarsal head. To return to the orignial point, whether or not the fore-foot has been lowered in the shell to make for a wider fit is probably a less important question than if there are other construction differences that make the F1 LT fit differently than the Alien RS, even with the same scaffo.
In use, between the Zeppa-based heel raise and the added spoiler, the LT feel much more aggressive in its forward lean (even in the 9-degree position), much more like a TLT7/8 than an Alien-family boot. Minimal vert skied on the LT so far (and in abysmal snow), but it may be the perfect boot for skis (eg. Ski Trab Mistico) that demand more forward pressure and a more knee-bent stance, and for which the Alien RS's more upright stance was never ideal. Nessun scarponi é lontano: the perfect boot is never far away! :-)

Hi, I'm curious how you would compare these to the TLT8 Carbonio in downhill performance and fit? Thanks!
11/20/2020
Hey Kyle,
Great question! Performance wise, they both punch above their weight class. However regarding fit, the two couldn't be further apart. The Scarpa is fairly narrow while the Dynafit is wide! Ultimately what will fit the best will perform the best for you.

I wear a size 27 in my Alien 1.0 and also my Scarpa Freedom RS boots. Is it safe to assume I'd wear a 27 in these as well?
Thanks.
Thanks.

Hey Bruce, yes this would be a good assumption. The F1 LT will just have a slightly wider last width than the Alien 1.0 but the fit should be fairly comparable.

Hey Skimo, now that you have these in stock, care to elaborate on the instep height? Similar to someone else, I also have a low instep height, and found the Atomic Backland Carbon to be too high volume around there too.
11/2/2020
Hi Allen, I'm not surprised about the Backlands! The F1 LT is certainly less cavernous, and in fact it can be a bit of a challenge to put on if you have a high instep, with the gaiter being the crux. However, like the Alien RS, it's not a great boot for truly low insteps as you'll have to crank down on the BOA which can over-stress that system and lead to failure. In other words: medium volume.

Got my hands on a pair of these early, haven’t skied them yet so this is purely a review on fit as compared to the Scarpa F1. Figured there are a lot of people coming from the F1 side that want to know if these will work. I have a couple seasons on the F1 (size 26)and they have been my favorite touring boot ever. They just fit me right out of the box, super snug but not too tight, just right. Last season tried on a pair of the Alien RS (size 26) and they were way too narrow, no go. When I had the chance to get a pair of these (size 26)without trying them on first I decided it was worth the risk. I made the right choice, these might fit better than my F1s. They are perfectly snug everywhere but actually have more room in the toe box than the standard F1. Not sure how this is possible if they say the last is 2 mm narrower than the F1, but I’ll take it. Other things I noticed, just based off living room feel I’m going to ditch the power strap just as I did on the F1, feel plenty stiff. Really like how my transitions will be exactly the same as the F1. The rest of the boot looks really well built and thought out. Can’t wait to ski them!

I am starting up touring again this year (covid goal) I Still down hill ski pretty frequently but I have not toured in sometime. Would this be a good boot to begin with? I like the fact it is light and would likely be easier to move on. How is warmth factor on it? I also take a women size 11, which would be a Mondo 28, would you recommend sizing down? or just stick with a 28?
10/20/2020
Hey Kat, thanks for reaching out! We have not skied on this boot yet, but it should be moderately warm. There are definitely warmer touring boots out there, but they will all likely be heavier than these. As for sizing, fill out our online Boot Fitting Form with any boots(resort or touring) you've skied in or tried on. Then we'll help find the perfect boot for you!

How do you compare them with the Atomic Backland Carbon 2019 ?
Do they have less volume near the ankle joint (feet instep) ?
I have low arch feet and had too much volume in my atomic.

10/6/2020
Hey, Hadrien because we havent received the new F1 LT boots yet we can't quite say if the volume in the rear of the boot will be that much narrower. What we do know is that the older Alien RS is a lower volume boot than the Backland and since the new F1 LT maintains the same lower shell it should be similar.

It looks like they ditched the tongue, but I can't find any videos of people opening these up. Tongues or no?
9/7/2020
Hi Simon, there is no tongue. The LT is based on the Alien RS design which gets its (surprising) stiffness from the spine, supported by the carbon-infused lower. It's nice getting in and out without having to fold a tongue out of the way, à la F1 and Maestrale.

Another fit question: I have been in a 28.5 F1 for a few years and a 28.5 original Maestrale before that. Both fit very well. Any suggestions for 28 vs. 29 in the F1 LT? Thanks!
8/27/2020
Hey Andy, I would recommend going with size 29 as the 28.5 fits similarly to the 29.
Answer this question:
8/8/2020
The Scarpa Maestrale RS is by far the best fitting and skiing boot I've toured in. It felt like it had already been fitted to my foot when I sat down and tried it on at Skimo for the first time.
Then I tried the Dynafit PDG2 to explore lightweight options. After lots of fitting it still fits and skis terribly (for me). Maybe I need the crutch of a big boot to compensate for lack of balance and skill?
Anyway, I'm interested in this new F1 LT. Is there any similarity in fit between the Maestrale RS and the new boot? Similar sizing? And, most importantly, can the shell be blown out around the MTP joints?
THANKS

Hey Dabu, the F1 LT should have a last width that is maybe a millimeter or two narrower than the Maestrale RS. The PDG 2 is essentially the TLT7 lower shell, which has a significantly wider and higher volume fit than these other boots. The F1 LT's lower is the same as the Alien RS, which Scarpa says shell punching voids the warranty for. The Carbon Grilamid LFT may be slightly less workable in certain areas, but we have absolutely punched the Alien RS for customers who accept the potentially voided warranty.

Hi. Wondering how the sizing on these boots compares to Alien RS and the old F1? Last width, length? Largest size will 31 - does that mean the new F1 31 is the same as RS 31? Thanks.
7/10/2020
Peter, Yes the lower is the same as the Alien RS, which had 99mm last. Scarpa is saying the F1 LT is 100mm. The change, according to Scarpa, is they lowered the footboard a bit, giving a slight bit more volume and lowering the foot to the widest part of the shell. If you tried the Alien 31 and it did not fit, this probably will not work either.

Andre, The lower shell is the same as the current Alien RS which had 99mm last. Scarpa is saying the F1 LT is 100mm. The change, according to Scarpa, is they lowered the footboard a bit, giving a slight bit more volume and lowering the foot to the widest part of the shell. Those widths are for a size 27 shell. In the larger sizes, the width is a good bit more. From customers who got the first 31 size this season, people with a med to wide foot still did not fit well.

Andre, It will be available up to a size 31. We have the current Alien RS in 30 and 31 now. Those sizes in a new model may arrive later in the Fall than the smaller sizes.
