Boreal Mutant

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.
