The lightest and best-insulated technical mountain boot in the Nepal family embodies the artistic model of technical high-altitude boots for mountaineering with crampons in high mountains and mixed terrain. Nepal Cube is, as the name suggests, a new starting point and a new standard for technical mountain boots, thanks to its exceptional lightness (only 950 grams per shoe) and high thermal performance. The low weight is made possible by minimizing the weight of the sole/midsole package, which features a highly insulating honeycomb-shaped carbon tech insole. Global comfort is ensured by the use of the Gore-Tex Membrane Insulated Comfort, providing breathability and waterproofing, as well as the EZ OUT technology of the tongue with its improved fit adjustment and enhanced sweat transport through the mesh fabric. Walking is supported by the three-directional 3D Flex System at the ankle, which provides support for the ankle on any terrain. The Vibram sole with Impact Brake System absorbs shocks, aids in ascent, and increases the braking effect during descent thanks to the differentiated diameter of the shoe lugs: Nepal Cube, the origin of a new species.
