To climb the hardest routes and boulders, a shoe must excel in all areas; to find friction wherever it appears. Edges, smears, heel and toe hooks; any of these may be needed to ensure a successful ascent. With the Boreal Mutant, there is no compromise.
The Mutant features a highly asymmetric and downturned last to optimally position the foot on steep rock. 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 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.

This video talks about Mutant at 2:10
The Boreal Mutant is a soft, sensitive, face-climbing shoe that blends the edging power of the Five Ten Hiangle with the greater versatility and precision of the Sportiva Miura Lace. It is slightly higher-volume than both of those options, so the Mutant performs well while maintaining an extremely comfortable fit. The Mutant isn’t the most aggressive shoe on the market in terms of either downturn or asymmetry, and the lack of reinforcement under the toe box shows a clear emphasis on sensitivity over supreme edging power. So if you are looking for a shoe for steep limestone or endless granite credit-card edges, you’ll find options that cater more directly to those specialties. But anyone looking for a shoe that performs across a diverse set of climbing styles will be very, very well served by the Mutant.
