The Scarpa Wrangell GTX is a mountaineering boot for heavy duty loads in the alpines. The Wrangell GTX Uses a Gore-Tex lining for waterproof protection in wet conditions. The tall cuff supports the ankle while a double tongue and Pro-Flex XT insole provide a comfortable Fit. An EVA Midsole cushions against rocks and uneven terrain as you explore the peaks of your dreams. The 2.8mm Crosta Pro HS12 Upper is durable and takes on the unrelenting outdoors with a rubber rand for additional protection against debris. Vibram provides this boot with the M4 Tech sole, which has an aggressive tread and plenty of cushion. The boot can accept walking crampons only (sorry, no Climbing crampons) for icy situations, so strap 'em on when needed.
