These features are achieved from the reduced weight of the sole/midsole using a Carbon Tech honeycomb, a thermal footbed and lightweight mini steel parts. The GORE-TEX Insulated Comfort lining contributes to the overall comfort of the boot, guaranteeing breathability and water resistance. EZ OUT technology for the tongue allows more precise regulation of the fit and encourages the elimination of sweat via a mesh fabric which draws humidity to the surface. The 3D Flex System provides comfort during walking and support for the ankle on steep terrain. The Vibram sole with Impact Brake System absorbs negative ground impact, while the graded lugs promote traction and keep feet in check on downhill terrain. Nepal Cube: the origin of a new species.
