    Tread heavy.

    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.

    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.

    feel nice

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 45.0

    I am not a trail runner, and I don't know a ton about trail running.
    But the Mutant does make a great lightweight hiking and approach shoe.
    Sportiva's mesh upper doesn't weigh much, and it is really breathable, while the midsole is supportive enough, and seems to keep my ankles pretty happy on longer days. They're burly enough for most of the hiking I do, and I like wearing them more than heavy boots with comparable support.
    I'll occasionally hype myself up for some cardio, and go on a run somewhere. The Mutants are fantastic in those scenarios for the same reasons that they excel elsewhere. Likewise, the heavily lugged sole is super solid through the slippery, in-between seasons.

    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!

    Great Shoe But Rubbing Issues

    best trail runner in the universe

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 45

    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.

    Great Shoe for my foot

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 44.0

    It took a couple of runs for the shoe to break in and for my foot to get used to it. Now, after 200+ miles, I love it. I have flat feet, wide fore-feet, narrow heels, and multiple skier bone-spurs.

    The sole is stiff, nearly like a hiking boot; this is a plus for me. I have weak, skinny ankles, and the stiff sole to support my feet and ankles wonderfully. I also have weird, narrow heels, and I have not gotten heel blisters from these guys. After long runs, 12+ miles, I have gotten toe blisters, but thats also been the case with every other shoe I have worn.

    I like the lacing system and overlap system; my only complaint is that it doesn't go down quite low enough over the forefoot.

    For as burly as it is, I find it lighter than my UltraRaptors.

    Great shoe, and I imagine that is partly because I have a weird foot and they fit me.

    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.

    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.

      Not for high arches

      • Familiarity: I've put it through the wringer
      • Fit: Runs small
      • Size Bought: 9.5

      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.

      My Best ones!

        I love how they fit how light they are and traction as always is great! Just ordered my second pair.

        Great Hiking and Mountain Shoes

        • Familiarity: I've put it through the wringer
        • Fit: True to size
        • Size Bought: 9.5 (US)

        First the things that make this shoe awesome:

        The fit on the upper of these trail running shoes is excellent. Second only to Salomon shoes in terms of comfortably keeping your feet totally locked down. This makes it easy to run up and down steep or rough terrain without worrying about your foot moving around in the shoe which can cause blisters or twisted ankles.

        The sole of these shoes is the stickiest of any trail running shoe I have tried. The sticky rubber La Sportiva puts on these is seriously awesome and the tread pattern mirrors those on my moutineering boots. Unsurprisingly, these shoes have unbelievable traction on mud, scree, and wet smooth rock.

        The things that make this shoe not so awsome:

        The break in time of these shoes was surprisingly long. For the first ~75 miles of use after about three hours there was an uncomfortable pressure on the balls of my feet.

        These shoes absorb a lot of water when they get wet (which makes they heavy) and take an annoyingly long time to dry.

        The laces are not as durable as the rest of the shoe. I have had a couple pairs of laces wear out and break by the top rungs of the shoe due to the friction between the fabric lace holders and laces. Breaking a lace in the middle of a several day long hike is pretty annoying.

        These shoes have a fairly high platform due in to a reasonable amount of cushioning and the deep lugs which I find not ideal for fast running around turns.

        Despite their flaws these are my go-to shoes for mountaineering approaches, and mountain running in steep places like Alaska and New Zealand.

        Gregory, thanks for your awesome review of the Mutant! Glad to hear these have worked out for you so far. I'd have to say I'm pretty envious of your trail running trips to NZ. Do you have any trail running plans for the summer? Reach out to me any time to talk running gear or endless singletrack trails!

        Kept my feet happy on the JMT

        • Familiarity: I've put it through the wringer
        • Fit: True to size
        • Size Bought: 43.5

        Balled out with these bad boys for 215 miles. If you're thinking about the Mutants for a thru hike, do it. I put in about 17-22 miles a day, and they were comfortable the entire way. I had no foot pain and essentially zero blisters for the entire trip.

        -DANK colors
        -Effective lacing system
        -Great sticky rubber
        -Effective tread pattern
        -Sufficient support/no problem cruising through talus
        -Unique (not a huge deal, but seeing Cascadia 10s everywhere gets boring)
        -Consistent with La Sportiva sizing

        -The stickier Frixion Green rubber doesn't last quite as long as the Blue (hard to call this a con--ought to be expected)

        Matt, thanks for your great review of the Mutant! Happy to hear they worked out for you on the JMT. I actually guided that trail about a year ago! I hope to go back soon. Do you have any big treks planned for this summer? Reach out to me with any backpacking gear questions directly, or to just talk about endless singletrack goodness ---

        A great all terrain lightweight hiker

        • Familiarity: I've put it through the wringer
        • Fit: Runs small
        • Size Bought: 47

        I've been wearing the Mutants for a few months now and have really grown fond of them. I had been wearing the Crossover 2.0 GTX all winter, and was excited this Spring when I saw how much they had in common with the Mutant.

        The Spyraltongue hugs the midfoot for a very secure and comfortable hold in the upper. The heel is perfectly narrow for my foot, and I have no slippage in that area at all. The toebox is a little wider than the Ultra Raptor, in line with the Wildcat 3.0, which is a very good thing in my eyes. The only slight knock on the upper is the material, which is very comfortable and durable, but not the most breathable or fast-drying. I wear a size 12.5 in almost all shoes, but a 13(47) in all La Sportiva. This shoe fits true to size.

        The midsole is plush yet very responsive. I've worn this shoe on a number of long hikes with a max distance of 22 miles miles and 7,200 feet of elevation gained. There is a plastic stabilizer in the heel area which offers a nice amount of stability, without getting in the way. One slight knock here is the absence of a rockplate or forefoot protection. The cushion is adequate for most trails and trail conditions, but I tend to feel a little bruising on the really rocky stuff.

        My favorite part of this shoe is the outsole. It is the same pattern as the Crossover 2.0, but swaps the harder Fixion Blue for the softer and stickier Frixion Green. This is the same rubber compound used on the Ultra Raptor. I've had nothing but very positive experiences with this outsole. It has handled sand, hardpack, mud, talus, and just about everything else I've thrown at it.

        A very nice shoe for those looking for a lightweight trailrunner, with excellent traction, great durability, a touch of stability and protection, and great looks.

        Prefect blend

        • Familiarity: I've used it several times
        • Fit: True to size
        • Size Bought: 10.5

        I log a lot of miles, almost all of them on trails and have tried out a lot of different shoes in my day. I just got a pair of Mutants and have been really impressed by the fit, support, and cushioning. I know all feet are different, but with it's wrap-around upper, the Mutants really fit my bony feet like a sock - no movement or hot spots whatsoever. It feels light on the foot and is super nimble on technical terrain. The Frixion La Sportiva soles really excel on muddy or slippery trails. No determination on durability as yet, but I've always been impressed with La Sportiva's longevity. I still use my first pair of Raptors as approach shoes after 400 miles on the trail. It's certainly worth trying some on when you get the chance.

        Agreed - just picked up a pair. Best fit and technical terrain performance since the original Crosslites (still have a few fresh pairs of those stashed away in the back of the closet) - instant classic! Happy to see a new design compatible with hobnails for winter running on ice and snow.

        What's the sizing of this shoe comparing to the La Sportiva Bushido?? I use size 12 US for the Bushido and runs perfect. Thank you!

        I can't speak for the Bushido but I can for the Anakonda, quantom, electron, wildcat, helios shoes and the Karakoram and Spantik boots. I wear all of them in the same size 43.5.

        La Sportiva fits pretty much the same across the board!

        I love this shoe, the cushioned version of the Anakonda
