ALIEN 1.0 (NEW)

The ALIEN 1.0 is a race-bred ski mountaineering boot built for athletes who measure success in vertical meters and podium finishes. Built on a 99mm last with a Carbon Grilamid® LFT shell and full carbon cuff, it delivers the torsional rigidity and featherlight response that elite skimo racers and high-output alpinists demand. The Speedlock Lite ski/walk mechanism transitions instantly between modes, while the BOA® Fit System + cord closure dials in precision fit without removing gloves. Underfoot, the Vibram® UFO outsole grips approach terrain with confidence before you ever clip into a binding. At 785g per half pair, the ALIEN 1.0 doesn’t ask you to choose between speed and performance, it delivers both.

• Carbon Grilamid® LFT Shell + Carbon Cuff — Full carbon construction delivers race-proven torsional stiffness and minimal weight, so every watt of power transfers directly to your skis
• Vibram® UFO Outsole — Purpose-built rubber compound provides reliable grip on mixed approach terrain, bridging the gap between boot and mountain
• BOA® Fit System + Cord Closure — Tool-free micro-adjustable fit system locks the foot precisely in place, even with gloved hands in the coldest conditions
• Speedlock Lite Ski/Walk Mode — Instant-release walk mechanism with 9°–13° adjustable forward lean lets you move efficiently on the skin track and charge hard on the descent
• Intuition® Cross Fit BT Liner — Performance-tuned heat-moldable liner wraps the foot in custom comfort, reducing pressure points across long race days and big mountain objectives
