Mountaineering boots designed for extreme expeditions to the Himalayan peaks that meet the needs of the mountaineer. Waterproofness, sturdiness and excellent protection are the characteristics at the base of our research into better shock absorbency and lightness, which exploits the most advanced technology that the footwear industry has to offer. The 8000 EVEREST EVO RR mountaineering boots have been especially designed for high altitude expeditions. The removable inner bootee guarantees optimal thermal insulation, the new Vibram® Penia outsole has deep-set, multi-directional lugs for better traction and durability. The double-density PU wedge (rigid PU and shock absorbing PU) guarantees better absorbency and support as well as lightness. The carbon fibre insole with honeycomb structure thermally insulates the inner bootee while maintaining the heat generated by the outsole of the feet. The rubber rand and the PU heel offer more protection against scratches and lacerations. The high gaiter is waterproof and the YKK zip is resistant to water, wind and UV rays. The excellent thermal insulation characteristic of the 8000 EVEREST EVO RR has been certified by the CIMAC institute for temperatures up to -30°C (in a static environment), but the mountaineer can face more rigid temperatures of up to -60°C during physical activities. Compatibility with step-in crampons makes these boots the perfect choice even for high level winter expeditions.
