When standing on razor-thin edges, maintaining tension with cheeky toe hooks, and doing so for multiple pitches, we're thankful to have the Ocun Sigma Climbing Shoe laced to our feet. The unique split-sole design features a sole that extends two-thirds of the way toward the heel rather than stopping short of the arch, giving us the support we need to fight off fatigue on long climbs while still maintaining flexibility for reliable hooks. Equipped with a dual-layer midsole, this shoe not only drives power to the toe but has a midsole layer that curves up over the sides to also drive power into the edges. The closure system has the laces offset, eliminating pressure points on the top of our foot and making room for a generous 3D-printed toe patch.
