    In any even, this is another really great and solid shoe from La Sportiva.

    While for most purposes I would prefer lower lugs, the Mutant has performed admirably on all terrain, even the road.

    I think the La Sportiva Mutant, while certainly at home on technical terrain, is a really well-rounded trail running shoe that you should really think about for whatever trails you’re interested in.

    The Mutant is an enigma. The sole is thick, stiff, and so firm it borders on hard; the upper is small and narrow.

    If the focus is steep, off trail, scrambling, mixed mountainous terrain, where a very precise and locked upper, flexible toe, maximum sticky rubber traction and overall protection are the priority, the Mutant is the clear choice.

    Bottom line: the Mutant is a high-performing, versatile trail runner that excels navigating gnarly, middle-distance trails for those with narrow feet.

    It hugs every contour, almost like the minimalist “barefoot” shoes of a few years back.

    So, to summarise, the Mutant is a true beast of burden that will keep working no matter what the elements and the terrain can throw at it.

    Considering they are bomb-proof, I am starting to think that the initial concerns over the 330g weight are laughable.

    Although the upper fabric is light and comfortable, it is also substantial. I love this for the sake of durability.

    If you are a minimalist runner, these are not for you, however if you like a solid, tight shoe that gives plenty of sole and ankle support the La Sportiva Mutants are a dream for your feet.

    Out running I found this shoe had just the right combination of the two; not too much to risk ankle instability, but enough to keep impact to a minimum and take some stress off the achilles.

    I particularly like it, since it provides good protection and the shoes get very responsive.

    The top portion of the shoe is made of the airmesh material however I found my feet to be rather hot in the warmer temperatures, which doesn’t bother me until I get home and take them off.

Updates to Mutant

The La Sportica Mutant features the ultra sticky outsole for a maximum traction on slippery and muddy terrain. It also gives added durability to the shoe’s outsole unit.

It also uses the brand’s unique tongue. It still features the traditional shoe tongue but with added protection, keeping stones and mud from entering the shoe while running.

Mutant size and fit

The Mutant has a regular running shoe sizing. It is available in the medium widths. It gives perfect fit to runners with narrow to medium foot measurements. The heel is a bit narrow and the midfoot and forefoot have standard measurements.


The outsole unit of the Mutant uses the brand’s FriXion XF technology. It is a sticky compound engineered to deliver an impressive traction on rocky or technical surfaces.

It also uses the brand’s V-Groove technology with Impact Brake System that enhances the shoe’s braking power and decreases impact forces. The combining power of these two elements gives additional cushioning and traction.


The midsole uses the Injection Molded EVA that provides sufficient underfoot cushioning. This works well with the TPU Heel Stabilizer that delivers and enhanced fit by keeping the heel snug and secure.


The upper of the La Sportive Mutant uses the Air Mesh cover that keeps the foot well-ventilated. The foot will be kept cool and dry without affecting the shoe’s breathability features.

The shoe’s Spyraltongue delivers an easy entry and personalized fit while giving additional protection. It prevents debris from entering the shoe and works well with the shoe’s 4 Way Stretch Gaiter. The gaiter covers the upper and keeps shoes free from small stones and debris.

It also features the Fusiongate Lacing Harness system that serves as a support system, securing the foot especially the midfoot.

Lastly, it utilizes the TPU Toe Cap that keeps the foot well-protected sharp rocks and other trail hazards.
