Re-energize your climbing with a refresh on your technique--and, the Red Chili Voltage II Climbing Shoe. The next iteration in the Voltage line, this shoe features a powerful downturn that encourages precise placement while a medium-stiff shank provides support while you stand on the tiniest of holds. In contrast, the sock-like upper conforms to your foot and moves with you to keep your foot comfortable while offset, hook-and-loop straps enable customized size and shape adjustment.
