F1 XT

Expert ski mountaineers who demand uncompromising performance without the weight penalty will find their match in the F1 XT Men's. Built around a Grilamid® Fiber Glass LFT® shell and Carbon Grilamid® LFT cuff, the boot delivers a rigid, responsive platform that transfers power precisely on steep technical terrain, while staying featherlight at just 1,145g per boot. The Wave Lite Closure system eliminates pressure points and enables a dialed, anatomical fit, while the Overlap Shield Tech gaiter seals out snow and debris without adding bulk. A Speed Lock ski/walk mode transitions instantly between uphill efficiency and downhill control, and the Vibram® UFO LT outsole grips confidently on approach terrain. With a 100mm last, Intuition® Cross Fit Tour LT liner, and adjustable forward lean (11°–13°–15°), the F1 XT Men's is precision-engineered for skimo racing and high-alpine ski mountaineering objectives.
