The ALIEN is SCARPA's high-performance crossover ski mountaineering boot, built for uphill enthusiasts and athletes who want race-proven technology without compromising on versatility or value. Sharing the same 99mm last and Carbon Grilamid (R) LFT shell as the ALIEN 1.0, it delivers the lightweight rigidity and precision fit that serious skimo athletes demand, at an accessible entry point into the ALIEN family. The Speedlock Lite walk mode transitions seamlessly between uphill efficiency and downhill power, while the BOA (R) Fit System + cord closure locks in a glove-friendly, micro-adjustable fit on the skin track. Underfoot, the Vibram (R) UFO outsole handles mixed approach terrain with confidence. At 870g per half pair, the ALIEN punches well above its weight class. Scarpa Alien Ski Boots | 27 | Christy Sports
