Ultraventure 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. These Vibram sole trail running shoes feature a 30/25mm stack height (5mm drop) for a plush and protective ride. The fully gusseted tongue and an abrasion-resistant engineered mesh upper are optimized for breathability and strength, and feature drainage “gills” for water release and quick drying.
