The Mutant is a funky looking mountain-running shoe with an emphasis on durability, foot protection and stability rather than minimal weight. La Sportiva’s heritage lies in mountaineering shoes, and it has used the experience to produce a protective sole unit with a 10mm drop that works well on dry mountain terrain but is also good in mud and on grass. The Spyral tongue wraps the foot, giving a lot of adjustment to foot shape and adding to the stability; it also acts as a grit gaiter. The Mutant has a slightly wider fit than some La Sportivas, which
works well for longer-distance mountain running.
VERDICT: A tough and dependable long-distance mountain-running shoe.
