- The Mammut Nordwand 2.1 High is a boot ready for alpine expeditions and challenging ice climbs. This second iteration—in collaboration with David Lama and the brand’s Pro team athletes—now comes with a separate inner boot. It also employs the updated Base Fit 2.0 technology to prevent slippage.
- This version still carries an insulated carbon insole. Together with a Poro Wedge, it grants underfoot cushioning and support. A Vibram outsole renders grip on most types of terrain.
The Mammut Nordwand 2.1 High is a fairly true-to-size unisex mountaineering boot. It comes in regular sizes and standard (medium) width. To obtain a boot with the correct fit, women are advised to go 1/2 size down. Its snug fit is brought by the Mountaineering Tech last which has a tailored heel and toe box.
The outsole of this high-cut mountaineering boot is called the Vibram Teton. The aggressive lugs along the side of the sole help stabilize each stride. Its toe and heel areas have a larger ground contact to aid in ascents and descents. The small studs in the center provide multidirectional traction.
Providing users a cushioned and shock absorbent ride is the Poro Wedge. It is created using ethylene-vinyl acetate (EVA) which underwent a compression molding technique. To maintain lightweight cushioning and underfoot rigidity, the brand designers included the patented Insulated Carbon Inner sole. Also, this boot is compatible with crampons.
The Mammut Nordwand 2.1 High is a double-boot with an integrated gaiter. It is made of synthetic leather for scree and snow protection. The rubber rand wraps the base of the boot to enhance durability. The Base Fit 2.0, on the other hand, is a double strap feature which secures the heel, preventing slippage.
Thanks to the incorporation of a Thinsulate 200 B and a 100% PES lining, the warmth inside the boot is maintained. For breathability, it is designed with Chimney Ventilation to keep the foot dry and fresh.
Its closure system from the gaiter to the inner boot features different techniques. Its tall gaiter uses a zipper that runs diagonally at the top. The outer boot uses a PowerStrap and a Boa Closure System. Finally, the inner boot has a speed lace system which uses elastic loops. All these are part of the Easy Entry System of Mammut which aims to facilitate smooth on and off.
- The rated insulation of this boot according to EN ISO 20334 standard is 35 degrees below zero Celsius.
- The Nordwand 2.1 High is a B3-rated boot which is compatible with step-in (automatic) crampons.
