The Rubicon climbing shoe features a split-sole design ideal for overhung routes. It has a downturned profile for power and precision, with ultra-sticky Neo Fuse rubber for maximum friction. A sticky toe patch increases toe-hook security. The synthetic upper stretches about half a size for a better fit. The sock-style entry reduces dead space, and two hook-and-loop straps secure the fit. The medium-stiff midsole balances support and sensitivity for performance.
