Climbing Shoes Ocn Iris with a Low-Volume Slimtix Last

Ocn Iris is a low-volume climbing shoe developed for climbers with narrow feet. The Slimtix last has a low-volume instep and heel, moderate asymmetry and a relatively flat profile. A 2D Toe Soft midsole permits flex, and a 3D toe patch provides rubber coverage for toe hooks. CAT rubber 1.5 and a wide hook-and-loop strap complete the construction.

Features and Benefits

• Slimtix last: Low volume at the instep and heel.
• Midsole: 2D Toe Soft construction.
• Toe patch: 3D rubber coverage for toe-hook moves.
• Sole: CAT rubber 1.5, 4 mm.
• Upper: Microfiber.
• Closure: One wide hook-and-loop strap.

Practical Use and Fit

Iris is suited to climbers looking specifically for a low-volume fit and a shoe that flexes through the forefoot. Ocn identifies Greek and Roman toe shapes as intended fit profiles; individual sizing still needs to be checked.
