The La Sportiva Mutant is a serious trail shoe built for serious terrain. The most noticeable trait of the Mutant is the aggressive outsole with its burly lugs. It has the stickiest FriXion® rubber to ensure traction over wet and loose terrain. There is an injected molded EVA cushion that provides enough comfort to run for hours on end. The Mutant has a precise fit thanks to La Sportiva’s FusionDate™ Technology Lacing Harness and High Frequency reinforcements. The tech delivers a fantastic, locked down fit, while the added Spyraltongue™ Technology ensures your foot slides in easily. Tame the trails in the La Sportiva Mutant.
