Ocun Sigma are climbing shoes designed for your most challenging rock climbs. Their midsole is made up of two parts to provide you with unparalleled support - not only at the toe of the shoe but also under the arch. The central part of the sole is designed to be thinner than usual to allow for high sensitivity and a perfect fit. Meanwhile, the overall stiffness offers maximum confidence in technically demanding movements.
- Elaborate sole design for unmatched support and sensitivity
- 3D rubber coverage for toe hooks
- Flat laces, with a tongue pocket for storage
- Soft and thin microfiber for maximum comfort and lightness
