La Sportiva Mutant Review Facts
It’s time to hit the trails and tear up the turf with the La Sportiva Mutant! This off-road running shoe has been receiving rave reviews for its versatility and stability. Able to take on the trail and mountain range, the protection and grip the Sportiva Mutant offers can be used even on regular running surfaces and provides great performance no matter the terrain a runner traverses. Built to withstand the rockiest of trails, dirt, snow, and ice, this trail running shoe is going to wow you with its comfort, support, and durability.
From its ultra-sticky outsole that lets the runner grip even the most slippery terrain to its unique SpyralTonge technology in its tongue that features added protection to prevent mud and rocks from entering the foot chamber during a run, top to bottom the La Sportiva Mutant is a relatively lightweight trail running shoe that seeks to maximize the runner’s performance while keeping them protected when out on the trail. This durable trainer has a breathable upper made of abrasion-resistant mesh and anti-debris materials to keep the runner’s shoe free of rocks and dirt. Its midsole unit offers efficient cushioning and great heel stability, while the removable AT Grip Spike placed in its outsole’s forefoot provides additional traction while traversing soft and slick surfaces. A beast on the trails and a bit of a Frankenstein’s monster when it comes to being an assemblage of elements that make it a stronger, more durable trail runner than many other comparable options, it may be a ‘Mutant’ but it’s amazing grip and traction will work its magic on the trail and win over the trail running community at the end of the day.
The outsole of the La Sportiva Mutant is built with the same type of rubber used on climbing shoes, FriXion XF. Frixion XF provides the outsole with a highly sticky traction to help avoid slippage. It also has 6mm lugs on the bottom of the sole that are placed in directional opposition, known as V-Groove technology, which makes stopping quickly very easy, a feature La Sportiva has termed their "Impact Brake System". The outsole of this shoe is all about traction, and for this La Sportiva included AT Grip Spikes--removable spikes
that can be screwed into the forefoot of the outsole--to enhance traction on wet or slippery surfaces. Durable, sticky, and sturdy, the outsole of the Mutant aims to grip the ground and provide maximum traction no matter the integrity of the surface being traversed.
The midsole of the La Sportiva Mutant is injected with a Molded EVA that runs from heel to toe and provides good underfoot cushioning. The back of the midsole has a TPU Heel Stabilizer that runs from the arch of one side of the shoe to the other, forming a heel cup that keeps the heel comfortable and firmly in place while also absorbing impact shock.
There is a slight, but not significant, arch in the midsole to accommodate the arch of the foot. The cushioning of the midsole has been singled out by reviewers for praise, as many were surprised the level of comfort and stability
it provides, even after running for great distances on uneven, difficult terrain.
The upper of the Mutant is made from Air Mesh
, a stretchy material that provides a great amount of ventilation. Featuring a unique lacing system constructed to help support the upper part of the runner’s foot, this is the FusionGate lacing harness, which has a cord that is molded to each section of the shoe as lace fasteners. This helps prevent the laces from coming undone during a run and forcing the runner to interrupt their ride to tighten their r laces. The upper is also covered with a 4-way Stretch Gaiter that helps keep the shoe free from debris entering the foot chamber.
The tongue is made from the proprietary SpyralTongue technology, which is secured after lace-up to prevent slippage and keep debris from entering the foot chamber. In addition, the upper of the Mutant has a solid toe cap to help prevent injury to your toes while you run. The collar of the shoe is a bit higher than most other running shoes, but this is constructed to provide the runner with a snug and secure fit. Finally, the Mutant has a pull loop in the back of the shoe that is larger than the standard size one would find on most running shoes to assist the runner in putting on this shoe.
It’s often difficult to find a trail running shoe that keeps the overall weight pretty low. After all, a lot is put into a decent trail runner, especially one that’s trying to provide comfort and superior protection against the harsh elements of the outdoors. But with men’s coming in at 10.7 ounces/303 grams and women’s at 9 ounces/255 grams, the La Sportiva Mutant is a surprisingly lightweight trail running shoe. Chalk this up to the combination of the Mutant's foam and mesh materials that helps keep the weight off this shoe for it to be considered lightweight.
Trail running shoes—particularly those that offer a fair amount of protection against the elements—are usually not as well-ventilated as runners would prefer, but the La Sportiva Mutant is a surprisingly breathable shoe. Its upper is made with AirMesh material, which allows for the runner’s feet to breathe more easily, keeps the foot cool and dry throughout a run, and helps to keep sweat accumulation down.
The Mutant is a comfortable trail running shoe whose unique lacing system ensures that the runner’s foot will feel nice. Its outsoles traction and lugs absorb shock and allow the foot to hit the ground without taking the brunt from impact. Its midsole is injected with EVA foam, which is a responsive, lightweight material that acts as a soft cushion while providing solid energy return with each step. There is also no concern over sustaining toe injury, as the toe
box is comfortable, roomy, and protected by a solid toe cap.
Most runners agree that the hassle of having to retighten laces
can distract from a good running experience, which is why the La Sportiva Mutant is outfitted with a unique lacing system that allows for uninterrupted long distance running without needing to constantly adjust the laces. Its intricate lacing system also provides for a secure, snug fit after lace-up, with the Mutant’s tongue providing both cushioning and protection against debris and the elements.
The style of the La Sportiva Mutant will definitely grab the attention of onlookers and become a talking point when taking a rest during a run on the trail. It comes in a variety of bright color combinations, along with some neutral ones. The louder, more garish colors suggest an aggressive runner while the more muted color combos suit the runner who would rather keep their eye on the prize instead of on their shoes. But any way you cut it, the La Sportiva Mutant is flashy and features a unique lacing system that is sure to draw some attention. A runner wearing a pair will certainly stand out in a crowd—that is, until they’re back in motion and tearing up the trail.
Reviewers of the Mutant are in agreement about one thing: this certainly is a durable shoe. The outsole of the Mutant is made from La Sportiva’s FriXion XF technology, which is a sticky rubber usually used in climbing shoes. Its wide lugs are similarly durable, so runners won’t have to worry about the tread quickly wearing even after many miles are put between first step-in. There are a few reports of the stitching of the upper mesh under the tongue coming undone, and the stitching of the pull loop at the heel of the shoe similarly disintegrating over time but depending on how the runner treats their pair of Mutants—and how hard they pull or tug at the materials—this issue may vary widely from one runner to the next.
