Any shoe can get you to the base of a climb, but the Evolv Women's Rex Approach Shoe packs the technical features to keep going. The sticky TRAX rubber outsoles include an edging platform to help you make you way on long 4th class ridges, so you don't have to cover a couple thousand feet in your tight climbing shoes. Evolv used tough leather uppers and rubber toe caps to make the Rex Approach Shoe burly enough for the hike and any wide crack pitches you encounter.
The Rex Shoe by Evolv is a super comfy, supportive approach shoe for light hikes to the crag, scrambling, easy climbing and guiding. Designed to be street savy and trail worthy, the Rex is stylish, hip and also provides the ultimate in friction when out guiding or making that class 4 approach in Tuolumne. Constructed with high friction TRAX rubber outsoles and an edging platform built in, you get confidence in every foot placement you make. Built on a comfortable athletic shoe last with leather uppers and a rubber toe rand, Evolv also added a high quality gel honeycomb insole for even more comfort than ever.
