The Scarpa F1 LT Alpine Touring Boot epitomizes fast and light AND powerful ski touring. This boot will be the new gold standard for speed touring and technical ski mountaineering. The F1 LT is intended to be the predecessor to the beloved and cult-classic Alien RS. Scarpa wanted to make a more robust version of the Alien RS that could fit skiers' feet better. They did so by blending design features of the beefier F1 with the featherweight Alien RS.
The F1 LT carries the F1's cuff buckle and spring-actuated ski/walk mechanism. These components should be more durable than the single action, dyneema cord ski/walk mechanism of the Alien RS. A thin booster strap is added to the upper cuff and a rear spoiler to the boot's liner (the spoiler will give the boot more forward lean). The lower shell is the same mold as the Alien RS, however the footbed now sits lower in the shell. This lowering of the footbed will provide the boot with better handling and increase the last by 1 or 2 millimeters (the F1 LT will be roughly a 99-100mm last). The final design change for the F1 LT [from the Alien RS] is a web of ridges added to the cuff for improved rigidity. That's a slew of significant improvements for a more robust, more downhill oriented ski boot and all clocking in at 970 grams! That's only 70 grams more than the Alien RS.
The F1 LT (Light and Tough) is a perfect boot for the expert backcountry skier who wants to ski more, and more, and more after that. This boot won't hold you back with a 72° range of motion and sub-kilo construction (970 grams). But transition to ski down and continue to be impressed with the rigidity that comes from Scarpa's carbon-infused Grilamid makeup (both shell and cuff). The BOA closure system micro-adjusts to provide precise fitting on your forefoot. The upper cuff strap buckle [plus booster strap] lock your ankle into an aggressive skiing position for confidence-inspiring downhill performance. Congratulations Scarpa for creating a touring boot that pushes the development of fast and light skiing one step forward. Now grab a pair of these Italian masterpieces and go ski your dream lines with ease, then more after that.

Loved the boot, but need to return it in exchange for the F1. Being a unisex boot, I found that it was longer in height than the F1 and therefore when fitted had a huge amount of pressure around the main part of my calf. My neighbour found the fit to be exactly the same. Scarpa need to make an F1 LT in a women’s version.
How many boots have I tried?.....a f'ing lot. this one is better, finally.
I have been skiing with Scarpa boots for 6-7 years. I started with Mastrle, then went light with Aliens. I skied alien for several years then went to Alien RS about 12/2019. My RS boots boa failed and we could not get repair stuff timely (like next day, this is ski season!) out of desperation to ski I bought the F1 LT. I am beyond happy! 2 days after purchase I did a 3200’ skimo. Zero boot performance issues. In the now two weeks I’ve had them, I have skied almost 15k and love the boot. It is only a few grams heavier than the RS. The transition is a bit longer with the heel and the top buckle, but I’m not that fast anyway and I am loving the stiffer boot.
Bottom line: I am loving this boot. Not sure what I’ll do with the RS when it gets repaired.
Love love love this boot so far, though only have a couple brief tours on them yet.
This is my first set of dedicated touring/mountaineering boots, previously in some heavy maestrales I scored through Sierra Trading. I had no idea boots could be both super stiff on the down and full range of motion on the up. I do have 1 hot spot to dial in on the medial heel, though don’t suspect it will be a long term issue.
More to come as I hope to beat these up on plenty more tours this season and beyond.
Thanks to Mike and Cripple Creek BC in Denver... a great experience all around!
Scarpa keeps upping their game, out of the box this boot fit my wide foot without having to heat or mold the liner. The boot has a good stiff forward flex and skied well on hard pack and first tracks in powder. And is super light. Only negative it may not be as warm as the older Scarpa boots.
Doug's review is spot on. Great on the uphill. Just need to get the strap and Boa tension right to get the heel to lock and avoid hot spots. Seems difficult to replicate the exact perfect tension on these over any other boots. The transitions aren't hard but seem to take some time. You'd think it's simple to revelcro two straps, adjust BOA and flip the lever down but it's a bit longer than you want, even if you Sharpie your straps for the right place. It's not a bad thing per se but no other boot - even larger boots - seem to take as long. The down is incredible and drives your boards well with a great flex (for a 1000g boot, let's be realistic). The fit is surprisingly better than the ALien RS. That 1mm difference in the last (on paper at least) goes a long way. Couldn't fit in the RS, i fit like a glove in the LT. This boot's replacing my Sytrons and TLT8. Don't race but feel like i have race-ish weight boots on the up and the down. These and a pair of Hoji Pro Tours cover the entire winter, from BC to the resort. If you want lightweight but still want to drive your boards, hard to not go this route unless they're too narrow.
I took these to the resort today just to get a feel for how they skied and get used to the lightweight stuff again. They were exceptional. I previously had Fischer Travers CC's, and these skied noticeably better, despite barely any difference in weight. The flex was surprisingly smooth, and overall they were comfortable and surprisingly confidence inspiring. I had to ski a little less aggressively than normal, but not by too much. (As a point of reference for what "aggressive" means, this is only my third season, so I'm not straightlining bumps or anything even on alpine gear. On the flipside, the boots were easy to ski even for a newbie like myself.)
The flex feels like about a 90 (I'm comparing them to Lange SX 100's). I felt like the boots were very responsive to small movements and I felt like I had a good connection with the snow, without feeling like I was getting banged around. Played around on everything from groomers (inlcuding plenty of moderately soft crud) to barely covered rocks to a few inches of powder today, and the boots felt responsive everywhere.
I was using them with older Scott Speedguide 80's (~1100g/ski) and G3 Ions. They're actually the stiffest skis I own and with the Fischer boots I struggled a bit to ski them comfortably. With the F1 LT's I felt like I was in control of the ski, not the other way around. My skiing mistakes today were tied to technique, not to equipment, and I didn't feel like I was getting thrown around regardless of conditions, which was a fantastic feeling for a newbie skier on lightweight gear.
As far as walk mode goes, I haven't taken them out skinning yet. But with carpet testing and walking around the resort today, the boots were not even noticeable in walk mode. I never hit the end of the range of motion. I also didn't feel a need to undo any straps in walk mode, I felt like I could get full ROM just by undoing the buckle. (For reference, I didn't have any of the straps insanely cranked. I'd describe the buckle strap as nice and tight, and the top strap as comfortably snug. They were plenty tight enough to ski.) So your mileage may vary depending on calf size, etc., but based on my experiences so far, I'd describe the ski/walk transition as a two motion transition (lever and buckle). No fiddling with straps required.
Hopefully that's a helpful review from a less experienced perspective. I'm personally thrilled with the boots.
