Tackle steep, snowy ridges, fat water ice, and technical mixed terrain with the Millet Mens Radikal Pro Mountaineering Boot. This fully-waterproof, double-wall insulated boot is built for serious performance at altitude, and its phylon honeycomb construction, fleece lining, and Boa speed lacing system make for a warm, light, ass-kicking boot that will help you push your limits in alpine terrain. An integrated neoprene gaiter and stretchy PU storm flap keep out snow and debris, and the low-profile Vibram Teton sole handles rocky approaches like a champ.
