Sigma

Technical climbing shoes for maximum precision on the hardest rock challenges

The high-performance Sigma shoes are built for the most demanding routes. Their unique two-part midsole provides precise support not only in the toe but also under the arch, delivering maximum control with every step. The thinner mid-section of the sole boosts sensitivity and adapts to the rock surface, while the 3D toe patch guarantees precise toe hooking.
