Happy days for the Scarpa R&D department, as they've successfully melded the ultralight elements of their cult-classic Alien race boots with the industry stalwart F1 to create the F1 LT. They're naming department, obviously, needs some work...

The F1 LT has borrowed the best of all worlds to create a ridiculously lightweight and reliable touring boot that handles technical ski mountaineering descents with aplomb. In other words, the F1 LT is a more versatile, backcountry-oriented touring boot, optimized for high-mileage missions, ambitious traverses, and technical ski mountaineering descents.

The Carbon Grilamid LFT shell and cuff delivers incredible power for such a lightweight design, while the 3D Lambda Torsion frame keeps you stable laterally and confidently provides power for the downhill, even on the fattest of today's skis. Yet, 72° of motion and the substantial weight savings provide a skinning experience you'll be psyched to repeat again and again. A waterproof gaiter system protects the comfortable liner, while the BOA Fit System locks it all down for a fast and secure fit. Finally, just remember, you're plugging these juggernauts into tech bindings.
