Inspired by rugged trail running shoes, the Ultra Raptor II Mid GTX Hiking Boot gives us reliable stability and lightweight agility.

We appreciate how its low-profile sole and midsole allow technical footwork and edging capability when climbing easier graded routes, while also offering semi-automatic crampon compatibility for glacier travel. The waterproof upper and GORE-TEX membrane keep your feet dry across mountainous terrain, and the gusset-free tongue construction increases comfort for long miles on the trail.

The inner boot is also made of Cordura+ for longlasting durability, and it's four-layer constructed with felt insulation and an aluminum layer that bounces body heat back. A removable liner insulated with EVA adds even more warmth, and it has a flex zone to ensure easy mobility up the mountain. Underfoot, the G2 Evo …
