One of the Best

This is the third La Sportiva shoe that I have purchased. My first one was the Ultra Raptor and I was impressed with it from day one, so when I started running with the Mutant, I could not help to immediately compare it to the Ultra Raptor. Now that I have done my first 100km of rough mountain trail... Read More

    Verified Buyer Reviewed by SwampRunner27 from Florida on Friday, August 4, 2017
    These shoes are among the best I've worn and run in. They fit a little snug, but that is perfect for when you are hitting the trails because you have no slippage. The soles are great and work about as good as cleats on a pitch when you're tearing up the trails; they grab pretty much everywhere including tree roots. They are not waterproof, but they dry super fast and the lacing system is very cool. These will require a little break in time, but not much. The insoles are soooo comfortable even for walking and hiking. You will not be disappointed in this shoe.

    These shoes have a few very unique features that seem to make people either love or hate them. The rubber is as sticky as anything I've seen outside of actual climbing shoes, the lugs are big enough to bound up loose dirt, and they have enough foot protection for me. I few of the unique items are the high foot, but below ankle fit, and the toe protection on the front. There is not a front plate in these so you have to be a little careful with foot placements if you're on sharp rocks. I've never owned better shoes on trails with a lot of exposed rock.
  • 3+ because of lack of sole durability
    Reviewed by ivebeen_framed from AZ on Sunday, July 30, 2017
    I really want to love these shoes, but I am getting cozy with the fact that I may need to change them out... My first run in them was uncomfortable because of how high the side panels come up the ankle and I have sensitive ankles (if that's a thing). I remedied this by putting a 2nd LS insole in to elevate my door to get the clearance I need... Since that mod, no issue and the slightly additional cushion is quite nice. Now the bigger issue... I have far less than 100mi on these and the treads are deteriorating VERY rapidly... Like knobs are starting to partially detach. I live in AZ and we run on desert and Rock. These would be perfect for that terrain with a more durable compound on the soles. The toebox, heel, and upper in general all feel amazing and they feel very light to run in. My Ultra Raptors with the harder compound have far outlasted these, but are not nearly as nice to run in.

    My first pair of trail runners that I got mainly to replace approach shoes, and that was a great choice. Great fit, super stable, light, and can handle any terrain. Great shoes even at full price, but STP always comes thru!
