Ozone HV (High Volume) is the wider-fit version of the popular Ozone, tailored for climbers with broader feet or higher insteps. It delivers the same high-performance features–precise support on micro edges, a rubberized toe patch for reliable toe hooks, and the patented 3 Force System that ensures maximum stability. With the Asymmetrix Plus last, offering more volume and width, it combines comfort with a secure fit even during long climbing days.
