Mutant Running Shoe

From fast, rolling singletrack to technical, rock-strewn climbs, the La Sportiva Men's Mutant Running Shoes handle it all. These aggressive, neutral trail running shoes provide a generous amount of cushioning for those longer runs, and they're fitted with TPU stabilizers to enhance the feeling of security when the trails get slick. The Airmesh uppers ensure a high level of breathability, while Spyraltongue technology allows you to dial in the perfect fit every time you head out for a run. Dynamic scree guards keep annoying hitchhikers out of your socks, and four-way stretch material won't interfere with the overall fit of the shoe. La Sportiva went with its stickiest sole on this shoe, resulting in even more traction, and then it opposed the lugs to enhance breaking ability, meaning these puppies climb like a billy goat and stop like a fox. 

  • Trail-running shoes with ample cushioning and aggressive shape
  • Airmesh upper with TPU overlays keeps air flowing
  • Four-way stretch dynamic scree guard protects and moves with you
  • Tempo 2 Ergo last promotes a more efficient gait
  • Airmesh lining further enhances breathability
  • Spyraltongue technology locks down the perfect fit
  • Injection-molded EVA midsole with TPU stabilizer cushions as you go
  • Frixion sole with V-Groove and Impact Brake System adds serious grip

Great shoe, runs small

    Fits great, after sizing half size up. Well made shoe with great grip-Will follow up after a few epic runs! So far so good...

    Super Sticky and Great Fit

    • Familiarity: I've used it several times
    • Fit: Runs small

    I'll start with the only downside I've found so far: Need to get a few size larger than what your normal shoe size would indicate; they run small.
    However, once you've found the size that works for you, there is nothing else I can complain about. The shoe is light, stable and breathes well. Once they are properly laced (that takes a little getting used to), they hold your feet supremely well and do not let rocks or other debris inside the shoe while hiking or trail-running. Super durable and incredibly sticky. I echo most of the commentary here in finding these shoes to have superb traction, even in loose rocks or wetter/muddier terrain. Would recommend to anyone looking for a comfortable and functional trail-running shoe.

    Awesome Mountain Shoe

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 45

    This has been my go-to shoe for most things mountain in the past year. Used in a variety of Colorado locations - Boulder foothills, Elk and San Juan mountains, etc. I have worn them in all sorts of conditions - dry, wet, rainy, snowy, sloppy, rocky - and feel comfortable in most. I definitely take these out in adverse conditions more so than other shoes (e.g. Hoka Challenger).

    The sticky rubber works fantastically. Lugs are solid and grippy and have held up for 400-500 miles. With their depth it can feel a little uneasy scrabbling up steep slabs (e.g. Flatirons in Boulder) as the lugs shift a little until they "set", but the stickiness of the rubber balances it out.

    Shoe is softer than an approach shoe, but firmer and more rigid than many lightweight neutral running shoes.

    Occasionally I would feel a little rubbing on the outside bottom side of my ankle from the top of the upper, but I just wore them for five days of mostly off-trail backpacking in the San Juan Mountains of Colorado with no problems.

    The side lacing system took a little while to get used to, but it keeps the lacing fairly snug with the z pattern (getting the lower laces snug toward the toes is a little tricky as the lace doesn't hold super tight down there, but it has never felt sloppy or loose regardless). The lace tuck-in stash on the side of the tongue is great as well - keeps them out of the way, and probably keeps them tied better!

    Shoes have taken a beating and the only major signs of wear are a small delaminating around the toe cap (which happened because I snagged it on a root), and a little blowout near the pinky toe (took 400+ miles though).

    I have worn 45s in the Wildcats, and 45.5 in the Helios and Vertical K. 45 in the Mutants fit me well.

    Definitely recommend these as stable, sturdy mountain running shoes that are still pretty lightweight.

    Awesome Mountain Shoe

    Great All Around Trail/ Mountain Runners

    • Fit: True to size
    • Size Bought: 11

    These shoes rock! I have had them for the 9 months or so and they perform great! I can push 10 + mile days in the mountains on terrain up to class 3 and have very happy feet at the end of the day. They are not as stiff as the La sportiva ultra raptors, but they are lighter. All at the same time they have great rigidness to take very rocky trails with ease. These are not as light as the Bushido’s but they are stiffer and able to take rough trails longer before feet get upset. If you want a stiffer trail runner and want to hit class 4 and minor class 5 terrain with super long hiking approaches on super rocky trail the Ultra raptor is your shoe. If you want to stack super long mile days with class 3 and under with rocky trail the Mutant is your shoe. If you want a bomb super light trail runner and occasional peak the Bushido is your shoe. Hope this helps you find the difference in a few superb shoes. La Sportiva for life!

    Stick to anything

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 10.5

    What I Love: I wear these for technical trail running around the foothills of colorado, and some easy 5th class scrambling. (also wore them for a 14 day trek in the Himalaya) They have a great fit, look great, and most importantly stay comfortable and have AMAZING traction in any terrain. Wet, no problem, loose/gravelly soil, no problem, steep rock scrambling, no problem they perform as well as some approach shoes. these are probably 150+ miles in and are holding up amazingly- very little wear.

    Nits: I have a wide toe box and they are a bit narrow there, they get a bit stinky but that could just be my own feet. I would definitely size up on these just a touch, as I have to wear thinner socks in order to avoid hot spots.

    Dream Shoe

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 46

    I've reviewed a lot of La Sportiva shoes (see my profile), and I don't believe I have that La Sportiva footshape. These may be may favorite (not including the TXn's, which are an approach shoe, but also rule) - one little nit-pick after I tell you what I like:

    OUTSOLE: the rockstar of this shoe is the outsole. If you want a trailrunner, with a sticky outsole WHILE ALSO having a aggressive tread, these are the shoes you want. The aggressive tread works in the wet grass, mud, scree, snow, etc, the stickiness works when things get technical. This summer, I used these shoes to climb every Centennial peak in Colorado, including the Crestone Traverse (5.2), Little Bear-Blanca Traverse (5.0), Jagged Mountain (5.2) (pictured), Wham Ridge (5.4) and the Maroon Bells Traverse (5.6). I'm a competent climber, so I do know the difference between a climbing shoe and a trail runner, and these trail runners give me enough confidence to take on these routes without fear

    The upper is great, very breathable, and dries fast.

    The nitpick is on the lacing itself: it's downright impossible to redo the lacing, if you need to put a new lace in them, without cheating to see just how the other shoe is laced up. It sounds silly, but it's true! I've never had the best luck with laces that are supplied with La Sportiva shoes - they make an incredible boot, then fall short on something as silly as a shoelace. Prempting this with a $2 pair from the store may just save your weekend.

    My only wishlist would be the heel drop: I'd rather have a more minimal drop, which these shoes def. are not - there's nothing minimal about them: they are well cushioned, very aggressive, stabilized shoes. It's not a big issue for me for trail runners, but this ain't an Altra fer sure.

    As with many La Sportivas, I chose a size much larger than what I usually use. My feet are very high volumed, but I didn't have a problem with the toebox. Heelcup may be a tiny bit too narrow for me, but way better than too wide.

    Dream Shoe

    Best Shoe I Have Ever Owned

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: 47

    This is an amazing shoe. I have temperamental feet and finding the right shoe is quite the job for me. I wear a size 12E traditionally. A 47 fits perfectly and surprisingly did not have to use my custom inserts. This shoe is amazingly comfortable and light weight. I have used these is varying conditions and terrains. I truly hope La Sportiva keeps this shoe around for a while. I will buy these as long as they are around.

    love, but not at first sight, try on 1st

    • Size Bought: 46 or 12.5

    these shoes are awesome in muddy, soft ground scenarios or scree. as mentioned they arent terribly grippy on dry rock like a climbing shoe but thats not what these shoes are for, get a bushido for that. so the person who reviewed these as an approach shoe doesnt understand what these are made for. that being said, they rule at what they are made for, with lugs like these, these are made for eating wet or loose trails.
    NOTE: sizing is waaay off for me. i wear an 11-11.5 is most things or depending on brand 45 or 45.5. approach shoes i sz 44-44.5 even within the la sportiva brand.
    i owned a pr of these in a 45, did an approximate 40 mile round trip approach to glacier peak in washington out of the box. they did wonderfully on the way up, but on the down the toe rub on my big toe and pinky was unbearable. depending on width i believe these shoes run a half sz to a full sz small. i repurchased a sz 12.5 or 46 and have fallen in love. an excellent shoe. BURLY but also for me runs more naturally than the 10mm drop would suggest. i also run in the salomon sense series and have run in the bushidos and helios 2.0 and sr. these hold my foot better than bushidos, which i believe is because of the lacing system which wraps the foot very well. i prefer the salomon sense normal and sg for most running, but for full days in mixed terrain, fastpacking, super nasty trails these things tear it up.

    a real treat would be the bushido sole with mutant upper...and more predictable sizing.

    Sticky and comfy

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: 40.5

    Ran 5 miles the first time I put them on including two trips up/down Stone Mountain(GA) and they were amazing. Great fit for me right out of the box (I think they run between 1/4/ - 1/2 size smaller US). No rubbing, the lacing system is neat, and the rubber bites on raw granite better than any other trail runners I've had. They don't have a rock plate so you have to be more careful that with other trail runners where you place your feet but if you slide the toe and heel protection is decent, better than my Adidas FastR. I'll have to see how they hold up but my initial ranking would put them at the top of all the trail runners I've tried. They'll be my go to dry summer hiking shoes as well.

    the Mutant does make a great lightweight hiking and approach shoe as well as running shoe

    Handles Choss like a Pro

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    Got these shoes for my boyfriend who has been trail running with them for years. Here is what he has to share:

    "The Mutants are a classic, hard to beat trail shoe that offers superior bite in loose or chossy trails. The construction of materials and lacing system combine for a super awesome fit on your cave man hands. The kangaroo pocket for the laces also helps keep things tidy while running. The fit for me is pretty dead on with as advertised. The rubber on these lasts pretty long compared to a Salomon, so I do enjoy the extended life compared to other trial shoes. I would highly recommend as a staple trail/hiking shoe"

    La Sportiva has done it again.

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 41.5

    As a person with a La Sportiva foot I've never had issues with sizing any of their shoes or boots for length. And lucky for me, the heel cup fits my heel. La Sportiva has nailed the right balance of weight and cushion in this shoe. They are using a tread pattern that I've had before in past shoes and love. I also like the fact that there is now a loop on the back of the shoe so you can clip it to your harness. The jury is out on the lacing. It works fine, but is a little funky the way it's offset. I also am glad it has the toe cap/guard. That is a nice touch as well.

    Great Shoe But Rubbing Issues

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 45.5

    I bought these shoes to be my main shoe for the 2016 TransRockies race. I've worn several other La Sportiva trail running shoes and skimo boots, and knew they fit my feet well. These were no exception - they fit very well. I didn't have any issues with them on my training runs but on day 3 or 4 of the TransRockies, they started rubbing a blister/bloody spot on my ankle. The shoes come up a little higher than most and the top of shoe was about half way up ankle, and about 60-70 miles into the race it started really rubbing my ankle. I had some pretty big scabs by the end. I've since started adding a couple pieces of tape across my ankle bone to prevent that chafing, and that has worked well. Other than that one gripe, it's probably been my favorite trail runner to date!

    best trail runner in the universe

    LOVE. 2nd pair and I don't care, they're not going anywhere (I hope). I would be sad if they discontinued this shoe because it is so great. Less of a rock plate than the bushido, but has more feel. The tread is super grippy but hard enough to hold up, I scramble the flatirons in them often. It sketches me out to scramble in the Salomon speedcross 3 cuz of the soft tread, these are very different. Good width in the toebox I have a pretty wide foot.

    best trail runner in the universe

    Not for me

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small

    I've been running for as long as I can remember and these are the worse shoes I've had. I've done a lot of minimalist and barefoot running for the past decade and wanted to try a more durable shoe so I had these and the Salomon speedcross 3.

    The mutants felt like they had a significant higher drop than the speed cross and I felt like I couldn't get my heel out of the way even though these have the same drop. I didn't have the same problem with the Salomons.

    The rubber was significantly sticker than other trail shoes I've used and bounds better than the speedcross.

    They did a great job of protecting my feet.

    I took them out on a 10 miler and ended up with the worse knee pain that ive had in a long time and the first blister I've had in years. That's more than likely due to how it changed my running style more than a defect with the shoe itself. If you are used to forefoot striking or minimalist running shoes I wouldn't look to closely at these.

    They got wet at the end of my run on a stream crossing and took about two days to dry out. They did drain very quickly immediately following the crossing.

    And finally the stitching was coming apart after 15 miles as well.

    I normally wear a 11.5 and got a 12 in these and they were a great fit.

    Thanks for the review Ryan. Super helpful to get this feedback out to the community.

    I wish I was lucky as everyone else

      It seems like no one has had stitching issues like I have on here, which has got me wondering if I got a bad apple. The stitching as can be seen is completely coming undone after a 13 miler peak out on mount Evans this am. My feet felt cozy as they do in most wide toe box trail runners and no blisters is a bonus. The material is light but I had excellent rock protection from the sole plate/rock guard. I also felt like I had ample toe protection from toe kick. Other than that these like many have said are a great trail runner and can be used for fast packing and hiking on all terrains with aggressive tread on the outsoles. Like I said above, the stitching is coming out on the top inside borders of the shoes. Other than that solid shoe. Let's hope for a good 1x1 exchange and a more positive experience in the future.

            If you have high arches these will crush your instep.

            I had to return them - the rubber also seemed very hard, which may wear out over time, but out of the box this shoe was pretty stiff.

            The overlapping "sock" inner is a little odd for a trail running shoes - (works great in their climbing shoes) - but as I strided the overlap began to bunch up.
