Wear the Asolo Men's Alta Via BV Mountaineering Boot on the approach, on the wall, or with a pair of crampons on ice. These do-it-all boots were built for mixed climbing at high altitudes, and as a result feature an intuitive design that's rigid and responsive but still comfortable enough to wear on long approaches. Their Gore-Tex Insulated Comfort membrane provides both warmth and waterproof, breathable performance, while their Perwanger leather upper is durable and water-resistant. Flex points at both the front and back of the ankle allow your ankle to move comfortably while you hike, but with Asolo's heel locking technology and injection-molded TPU lateral shell, the boots are extremely supportive when climbing on both rock or ice. The Vibram Vertical rubber sole is crampon compatible and is supported by a Pebax frame as well as an anti-shock PU insert in the midsole. An anatomic footbed ensures a comfortable fit, so you're not dying to pry these boots off after a long day in the alpine.
