The Mutant is shoe designed to climb the hardest routes and bouldering problems. A highly technical shoe with a very aggressively downturned profile and an asymmetric last.
The Boreal Mutant excels on very steep, very technical rock and is designed for high precision edging and smearing, as well as positive heel hooking. The highly advanced sole unit comprises a super-sticky molded Zenith™ rubber forefoot half-sole and one-piece Zenith™ heel cup. These molded sections have an accurate 3D shape to hold the foot with no dead space, and maintain their shape over time.
Thinner rubber is used in the middle of the sole to enhance flexibility, and ensure a close fit under the arch. The Lateral Torsion System, a band running around the heel and under the foot, securely holds the foot in place aiding power transmission across the shoe.
The premium quality unlined leather upper features our new “Friction Skin” coating for ultimate toe-hooking ability without the pain of a rubber toe covering and the simple elastic and single Velcro strap closure system ensures a comfortable, low profile fit.
The Mutant is the ideal choice for boulderers, competition climbers and sport climbers operating at higher grades or on steeper rock.
