The Zamberlan 4000 Eiger Evo GTX RS is high performance, high altitude mountaineering boot with integrated gaiter for increased insulation in extreme environments. This B3 boot takes a technical crampon for ice climbing, while the lightweight Vibram Penia sole provides added comfort when walking without crampons. A carbon fibre midsole provides the rigidity a technical boot requires.
