Mammut Nordwand 6000 High Mountaineering Boot

Nordwand 6000 High Mountaineering Boot delivers ultralight warmth and precision for extreme alpine summits

What Our Gearhead® Experts Are Saying:

"When I’m pushing into high alpine terrain or ice climbing at altitude, the Nordwand 6000s are my go-to. They’re incredibly light for a double boot, and the Boa closure makes dialing in the fit super easy with gloves on. The waterproof gaiter and insulated liner keep my feet warm and dry even when temps dive below zero."

When the route turns vertical and the air thins, the Mammut Nordwand 6000 High Mountaineering Boot steps up to meet the challenge. Designed for high-altitude pursuits and technical ascents, this double boot combines cutting-edge materials with alpine-grade warmth and precision. The Carbitex upper delivers flexible strength and low weight, while a waterproof gaiter shields against snow and ice to keep our feet dry and protected through the most demanding conditions.

Inside, a removable insulated liner and double-insulated carbon footbed work together to trap heat and block out cold for comfort down to -31°F. The Boa Fit System allows fast, glove-friendly adjustments, and the Vibram Litebase outsole provides exceptional traction while cutting unnecessary grams. Fully step-in crampon compatible, the Nordwand 6000 is built for serious alpinists seeking reliable performance from frozen couloirs to windswept summits.
