Balancing the fit and performance of a trail running shoe with the stability required for long, technical approaches, the Vertex Alpine redefines approach footwear. Made for all-day mountain travel, it’s light, fast, and delivers the support and protection required for rugged, varied terrain. The sticky Vibram XS Flash 2 outsole is designed for edging, on-trail performance, and grip in wet and dry conditions. A TPU shank and toe cap add protection, and a knit collar seals out debris.
