Fast and light alpine ascents require fast and light gear like the Scarpa Men's Charmoz Pro GTX Mountaineering Boot. Its Gore Tex Performance Comfort pairs a waterproof breathable membrane with a moisture wicking lining for the utmost comfort on active pursuits in high places. Scarpa's Tri Flex ankle gives the Charmoz Pro natural articulation so you can get up and down before anyone knew you were gone. Underfoot, Scarpa equipped this light mountaineering boot with a cushioned and slightly insulated Pro Fiber XT 20 footbed made of EVA. The Pentax Precision XT midsole uses different thicknesses of foam to maximize impact absorption efficiently, and the dual density PU heel insert enhances support and stability on rough terrain. The Vibram Mulaz sole includes climbing zones at the toe, breaking zones at the heel, self cleaning grooves, and semi automatic crampon compatibility.
