Light mountaineering in technical terrain calls for the Salewa Men's Rapace GTX Mountaineering Boot. Gore Tex Performance Comfort gives this boot waterproofing that remains highly breathable for active pursuits. Constructed with Salewa's innovative 3F System Evo, this boot provides a surprising amount of flexibility without ridding any much needed ankle support. Salewa built this boot out of a highly durable Cordura with nubuck reinforcements and a 360 degree rubber rand for long lasting use. The climbing style lace ensures a snug fit from toe to heel, and the Multi Fit Footbed offers customized comfort. The Rapace also features a nylon midsole for mid stiff stability, and Vibram's Mulaz sole has the rugged lugs you need to tackle any terrain.
