The UP Rise Zero is a high-performance climbing shoe that excels in any situation. The two-piece RH rubber sole and medium stiffness midsole allow the shoe to have the perfect amount of flexibility for a magic balance of edging and smearing capabilities while the VD rubber toe patch enhances toe hooks. The sling shot randing maximizes the two-piece sole design by hugging your arch and enhancing overall fit. The heel cup fit and rigidity have been optimized for heel hook performance, and the new Zero-Closure system allows you to adjust the fit with a single strap that eliminates pressure points over the top of the foot. Premium U.S. leather breaks in for the perfect fit for your foot as you wear the shoe.
