Centurion Review: The Mutant offers a different angle to any of the other shoes in La Sportiva's range. Its focus is on comfort and durability for long / ultra distance efforts, but with the grip to work on muddy trail and grass whilst also performing brilliantly on flatter, harder packed trail and rock. The mutant is called the mutant because it can do it all. The Spyraltongue™  is not a gimmick. It makes it easily the most protected and comfortable trail shoe in La Sportiva's range. With a high ankle cuff protecting your ankle and achilles. The mesh of the upper allows breathability without letting debris in. The rock plate is taken care of with the injection moulded EVA midsole - offering huge protection from sharp rock but remaining soft over easier terrain.
