Asolo designed the Women's 6b+ GV Mountaineering Boot for technical climbing on ice and mixed routes. Gore-Tex Insulated Comfort provides durable waterproof protection as well as the warmth you need in cold conditions. The boot's water-resistant Schoeller K-Tech Micro tech upper enhances its protection, durability, and temperature regulation for secure comfort. Underneath the 6b+ GV, Asolo's Duo Asoflex Ascent lasting board works hard to improve your comfort and performance in the vertical world. This board includes a supportive Pebax frame with an anti-shock heel insert that also assists in braking when you're descending. The midsole also includes fiberglass-injected nylon stabilizers and a cushy EVA cover. Asolo had Vibram make its Vertical sole ready to ascend the steep stuff.
