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.

Questions & Reviews
I use the 96mm with maestrales also on the resort, as for freeride powder and couloirs so will de F1 LT have enough power transmition to carve well on the piste as well good skiability on the pow?
Thanks for the help
The Scarpa F1 LT is quite powerful for its weight. However, at 995g in the 27.0 shell size, this boot does have its limits. I would not use this boot for lift-accessed laps, especially with the waist width of skis that you are looking to drive. Additionally, this boot is only compatible with tech bindings.
In softer backcountry conditions, you would be just fine on the 96mm waist width, but you will be maxing this boot out on the 106mm waisted ski. Another thing to mention, Scarpa states that this boot should not be paired with a ski above 85mm in the waist width, or you will void the warranty. That being said, plenty of folks use this boot to drive skis far wider than that in the backcountry with great success.

I am sure you have read the reviews, so you know that the F1 LT lives up to the hype! It is lighter than your TLT6, while packing quite a punch on the way down. However, to really dial in the fit on a new boot, I would recommend filling out a Boot Fitter. A lighter boot will pay dividends over that distance and vert, and will most likely be worth the investment!
The boot itself is amazing. My third boot and by far my favorite. I say the widest ski you want with these is 105 on powder (but you can ski anything in powder). Otherwise I would stick to 100 mm or less for underfoot.
The boot is durable. More durable than its heavier brother F1.
The fit is difficult. I ended up going up a whole size more than usual. Would not recommend buying online without a proper boot fit. Even then it’s a leap of faith. Spend the extra money for a proper foot bed with these too.
I wish scarpa could get the top strap figured out. I almost prefer a buckle but after getting used to how tight I like it it’s been much easier to figure out.
These things are mobile enough to drive in. Seriously.
You should be able to use this boot with ease! No need to worry about your height or weight.
I use them with skis ranging from 78 to 116 underfoot and have thoroughly enjoyed them with everything.
I had some concern about the gaiter stretching / wearing out with repeated liner removal/insertion so I bought a cheap in-boot dryer which has worked out fine.
The Liner of the Scarpa F1 LT is heat moldable. However, we generally recommend against shell work, as the shell is constructed out of carbon-infused Grilamid plastic, and any punching will void the warranty. If you have any further questions on boots, I recommend that you fill out a Boot Fitter, and we would be happy to guide you towards a boot that will work well for you!
That’s right the F1 light skis better than the F1.
Mostly due to its significantly taller cuff and more performance fit overall
The only critique I have is I could do without the Velcro, in place of a conventional buckle. I will say that the Velcro strap buckle system is much better with the adjustment numbers so that you know where to set it and forget it for the day (and incremental update from the strap on the older F1s. I have an incredibly narrow low-volume foot and by adding some standard boot fitting shims and pad material to take up space, they actually fit and perform perfect. I have a recently badly damaged right foot and my F1 light with an older broken liner is the most comfortable and best piece of footwear I own. Sounds like they fit mid range to wider feet as well which sounds impossible it seems to be working.
It’s worth noting that in eight years of skiing all iterations of the alien as well as the RS and the F1, I’ve only broken a Boa once. And it wasn’t a big deal to ski or replace.
If the game is about building the boot with the best tour-ability, combined with the highest downhill performance for the least amount of weight, this boot wins the whole game hands-down.
I am curious how these boots would be driving a ski like the Hyper V8? Or would that ski be too fat for these guys. Or would the regular F1 be a better fit.
The transition from up to down is a bit more clunky than the Alien RS, especially with the extra power strap (removable) but if you're not racing it's not really a big deal. The BOA is great but has limited range so some folks may run out of clicks before they are tight enough.
The down is what really impressed me. I like a bit more forward lean than the stock 11-degrees so I adjusted it to the 13-degrees setting and it felt much more responsive. The flex is more progressive than the Alien RS and the Fischer Travers CC (used last year). They are definitely the best skiing lightweight AT boots I've ever used.
