When the trail ahead is rock and ice, or no trail at all, Salewa's MTN Trainer Winter Boot provides the warmth and grip needed in the alpine. The suede and wool upper insulates against brisk temperatures as you climb higher up the ridge, while the Vibram Arctic Grip sole offers impressive traction on rock and ice. Salewa finishes the MTN Trainer 2 with features to ensure your comfort over long miles: a responsive footbed to keep you moving forward, a Gore-tex lining to ensure feet stay dry, and a stretch gaiter cuff to keep debris out of the boots as you hike.
