The second version of the Mont Blanc Pro is built around the latest Essential AC sole platform making this boot lightweight, durable, precise and ready for all you can throw at it. The AC sole Platform is usually more commonly found in the Phantom 8000 and was developed by Ueli Steck (RIP). The last is lightweight, cushioned but also extremely burly and durable. The TPU insert at the toe gives a symbiotic connection to the latest automatic crampons. The boot has been revamped, rebooted and remastered again for 2019. 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 Mont Blanc Pro one of the lightest boots in its class.The principal aim of the Mont Blanc Pro is to provide a perfect blend of cutting edge technology and last design with the robust longevity you'd expect from a Scarpa mountaineering boot. Based around the exceptional NAG last - co-developed by Ueli Steck to provide exceptional comfort for technical use with a strong emphasis on focusing the climbing power over the toe/front of the boot creating our most precise, technical mountain fit ever. The Scarpa Mont Blanc Pro GTX is an exceptional mountain boot for those looking for both lightness and durability.
