The 6000 DENALI EVO RR mountaineering boots have been designed for expeditions up to 6000mt and thanks to the removable, internal shoe offer excellent thermal insulation, protecting the feet against the cold. This model has been certified by the CIMAC institute for temperatures up to -25°C (in a static environment), but during use in movement the mountaineer can brave more rigid temperatures up to -40°C. These boots are ideal for high altitudes: the high gaiter, the YKK zip and the upper in Cordura® and microfiber serve as an impenetrable barrier against water and snow. These boots have also been made using the best technology that the shoe industry has to offer ensuring that the mountaineer has the best possible shock absorbency, lightness and grip. To combat wear and tear the Vibram® Penia sole guarantees the correct combination of support and sensitivity and the new insole in carbon fibre offers a superior rigidity, lightness and thermal insulation. These boots are compatible with automatic crampons making them suitable for icy and snowy routes and mixed rock and glacier terrains.
