Scarpa Alien 3.0 Alpine Touring Boot Mens

Italians know race performance and the Scarpa Alien 3.0 Alpine Touring Boot is cold, hard proof. Designed for speed-obsessed ski mountaineers and randonnee racers, this boot puts a premium on weight and uphill performance in every aspect of its design, from the carbon cuff and shell to the vibration-absorbing Pebax tongue. Weighing in at a touch more than a pound a piece, these kicks are lighter than some trail running shoes.

With the flick of the featherweight, strong A-light lever, you lock and release the cuff and shell in a single movement for a whopping 71-degree range of motion and lightning-fast transitions. Pressure points, hot spots, and boot-tinkering are the fastest ways to bring an otherwise efficient tour to a screeching, painful halt, so the micro-adjustable BOA closure system gets your custom fit dialed from the get-go and never loosens with time. A mountaineering-specific last and special Intuition Race 3.0 liner bootie blend comfort, performance, and function, while the addition of a convenient pull tab, soft foam instep, and high-density foam upper and toe box ensure your foot remains comfortable during long ascents.

Quick Step-In tech fittings speed up and smooth out the boot attachment process, but your objectives likely won’t be summited with skis and skins alone. Hence, Scarpa teamed up with Vibram to create the UFO 3.0 sole to cater to the usage standards of the International Ski Mountaineering Federation (ISMF). On the descent, the ergonomically designed carbon components crank the torsional rigidity of the boot all the way up for the demands of navigating technical terrain.
