Ultraventure 3 was designed with features inspired by our elite trail and ultrarunners. An aggressive Vibram® XS Trek outsole provides traction, durability, and protection on technical trails, while the 3 piece, multi-density EVA midsole offers light stability through the gait cycle. A 30/25mm stack height (5mm drop) delivers a plush and protective ride. The fully gusseted tongue of these ultra trail running shoes and an abrasion-resistant engineered mesh upper are optimized for breathability and strength, and feature drainage “gills” for water release and quick drying. Ultraventure also features our uniquely fitted gaiter attachment, making it fully compatible with our stretch nylon Topo gaiter (optional and sold separately).
