For quick movement in the alpine, the Vertex Alp is built to be fast and comfortable without sacrificing the precision, performance, or protection of a mountaineering boot. Unlike stiff, slow-moving boots, the Vertex Alp takes a cue from running shoes, remaining lightweight with a curved geometry and dual-density midsole to propel you forward. An internal harness holds your feet for better control on steep, varied terrain, and an ultra-grippy, ultralight outsole—plus crampon compatibility—ensures grip and traction in high-consequence zones.
