Combining the lightness of a running shoe with the rugged durability of a trail shoe, the Terraventure 2 features a 2-density injected EVA midsole on a rugged Vibram® XS Trek outsole. These women's Vibram running shoes feature deeper, more generously spaced lugs which improves underfoot traction in mud and slush and a flexible forefoot rock plate adds protection against rocks and roots. With a fully gusseted tongue, the durable mesh and PU printed upper now features drainage ports for water release and quicker drying. A 5mm anti-microbial Ortholite® footbed resists compression set and odor and our uniquely fitted gaiter attachment makes it compatible with our stretch nylon Topo gaiter (optional and sold separately). Like all Topo Athletic shoes, these durable trail running shoes feature a roomy toe box and a snug fit along the waist and heel.
