Why We Like The Mammut Nordwand 6000 High Mountaineering Boot

When miles of harsh conditions stand between us and the peak we desire, we kit up with Mammut's Nordwand 6000 High Mountaineering Boot. Vibram's low-profile Litebase tech and the rigid carbon insole save grams without sacrificing performance for an ultralight double boot that's as hungry for the summit as we are. When things get technical, the full crampon compatible design lets us approach mixed routes with the security of automatic crampons. From waist deep powder to crumbling ice, the toasty liner and double-insulted footbed hold in heat and the robust waterproof gaiter blocks out the wet, keeping our feet comfortably dry through it all.

Zipper catches, had to cut it twice

I've used it once or twice and have initial impressions

I don’t even own these boots but my buddy does and he brought them out to climb today for the first time. I won’t speak to their climbing abilities but the zipper caught 2x times leading to a ton of faff. literally had to cut the stuck material w/ a knife then use a v-thread tool to hook it out. After removing stuckage, we got on our climb and he wasn’t impressed w/ that either. Screw these boots
