F1 LT..

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.
