The Evolv Phantom LV Climbing Shoe (PSR 8) is a low-volume version of one of our most aggressively downturned climbing shoes for boulderers with narrow feet. A downturned toe box accents its aggressively cambered shape. The plastic midsole is thicker at the forefoot for a rigid downturn, and it gets thinner at the toe to provide the sensitivity that so many challenging boulders require. A stretch-resistant upper sports a 6-point single-pull closure for absolute snugness. We made the sole with our stickiest TRAX SAS rubber compound to keep a firm grip on plastic and all rock types. Rounded out with a Dark Spine S heel midsole, pushing more power through your foot to the toebox, there's a reason high-level athletes like Daniel Woods and Zach Galla wear this shoe.
