The Mammut Men's Nordwand Knit High GTX Mountaineering Boot is the first mountaineering boot built with a knit upper to provide exceptional comfort that doesn't skimp on weather protection or climbing performance. The knit upper is elastic to adapt to your foot's specific shape, and with Mammut's Base Fit 2.0 design, the Nordwand Knit High GTX should reduce blistering with its solid, comfy fit. Mammut laminated a Gore-Tex membrane to the knit upper for rugged waterproofing and comfortable breathability. The combination of Alumina, insulated footbed, and Duratherm insulation ensures warmth in sub-zero temperatures.

Underfoot, the Nordwand Knit High GTX has all the features you'd expect out of a high-performance mountaineering boot. There's a double-insulated insole made out of carbon for stiff rigidity that keeps the boot lighter than two pounds. This board-lasted, stiff boot also boasts a PU wedge at the heel for a bit of impact absorption. The Michelin Alpine Lite rubber sole boasts automatic crampon compatibility.
