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.
