The Mt Blanc Pro is a warm and durable boot designed for technical mountaineering and winter climbing. The Mt Blanc Pro is built around the latest Essential AC sole platform which is lightweight, and cushioned but also extremely burly and durable. The TPU insert at the toe gives a symbiotic connection to the latest automatic crampons. The upper is a hardy 3mm perwanger leather backed up with a GORE-TEX (Insulated Comfort Footwear) for cold weather use. The new ankle cuff design has an Exo-Ys TPU structure injected directly into the material, creating a really lightweight but supportive cradle around the ankle. The revised softshell gaiter is even easier to get into helping protect against snow and spindrift. The combination of PU Tek and rubber rand give the optimum blend of weight saving and reinforced protection, making the Mt Blanc Pro one of the lightest boots in its class.
