The Scarpa Mens Charmoz GTX Mountaineering Boots excel on varied alpine terrain where a pitch of snow is followed by a pitch of rock which precedes two pitches of ice. Waterproof breathable Gore-Tex inserts keep your feet dry as you posthole to the base of your route. The -length shanks allow comfortable walking on the approach hike. Vibram Mulaz soles give the Charmoz GTX Boots great traction on both snow and the techy rock climbing that gets you up the first few hundred feet. Strap a pair of Newmatic semi-automatic crampons to these Scarpa boots, and their rigid soles and flexible uppers give you the support and precision you need for grade 5 ice and hard mixed climbing.
