Andrew C. ★★★★★ Oct 21, 2026

Took these on a mixed snow and rock route and was surprised how well the low-cut design handled ankle support. The weight difference from my old boots is night and day, making technical sections feel much less tiring.

Christopher K. ★★★★★ Oct 20, 2026

Was a bit skeptical about the low-cut design for glacier travel, but after a full day on the Morteratsch, the weight savings really paid off—my feet felt fresh at the end. The GORE-TEX liner kept them perfectly dry through a wet snow section.

First time using a low-cut boot for actual glacier travel and I'm genuinely surprised how much support it gives without the weight. The Gore-Tex lining kept my feet bone dry crossing a wet moraine, and the minimalist design made scrambling feel way more agile than my old boots.
