La Sportiva's Mutant has an ultra-sticky sole that provides outstanding performance on slippery terrain, including mud or scree. These running shoes have a spiral opening, therefore, are quick-fitting. Featuring an integrated gaiter the Mutant protects from stones and mud. 

Features:

• Versatile shoes created for a number of off-road runs such as sky races, mountain running and city park running. High level of stability, shock absorption and comfort.
• Quick-fit shoes just like traditional shoes, thanks to the spiral opening of the gaiter.
• Ultra sticky sole perfect for running on soft and muddy terrain. Extremely versatile thanks to the AT Grip Spike feature.
• The soles are particularly suited to racing on the soft and muddy ground, due to the width of the shoe and the distance of the lugs that make up the sole.
• The midsole lends a High degree of cushioning to assist “push off” during the propulsion phase while running, making these shoes ideal for use on off-road trails. Furthermore, EVA Injected midsoles drastically reduce the “squash” effect of the EVA over time, allowing the shoe durability. 
• These Mountain Running® models use La Sportiva's exclusive eco-friendly insoles by OrthoLite® Hybrid, made using 20% recycled material from the production process.
• Eco-friendly and washable: they contain recycled rubber and are machine-washable.
• Maximum wearing comfort thanks to the insole ventilation and the highly breathable PU foam cells: the foot is always dry and kept at the perfect temperature.
• They facilitate the wicking of sweat thus keeping the foot dry.
• Enhanced durability thanks to the anti-compression technology which keeps material compression down to less than 5% over time.
