Three years of development have resulted in the Mammut Nordwand Knit High GTX®, the first fully crampon-compatible shoe with a knitted shaft. 3D Knitted Upper gives this robust shoe elastic and shape-adapting properties, bringing you the benefit of reduced weight in the terrain. Contact Control also allows a more sure-footed step. The Base Fit technology helps to prevent unpleasant blisters by providing an optimized fit. Easy Entry System makes it easy to put on and take off the boot and can be operated while wearing thick gloves. The patented, double-insulated carbon insole allows maximum weight reduction while providing rigidity and excellent insulation.
