Why We Like The Scarpa Alien 1.0 Alpine Touring Boot

The Scarpa Alien 1.0 Alpine Touring Boot is a true must-have for dedicated skimo and touring enthusiasts. The Carbon Grilamid LFT shell and cuff are as light and stiff as can be, saving our legs on the skin track before we go full tilt down steep chutes or massive trophy lines for the fast way down. The Alien 1.0 can get us anywhere on the mountain, offering unparalleled traction when we have to clip out of our skis so we can get over icy boulder fields. The highlight of the boot is the micro-adjustable BOA fit system that allows us to find a secure fit that eliminates dead spots and pressure points for maximum comfort and performance.
