The La Sportiva Ultra Raptor has been one of the most amazing hiking shoes I’ve ever worn from a performance standpoint. The combination of a grippy Frixion Green rubber outsole, and a cushy and protective La Sportiva midsole, make for the perfect combination. I’ve worn through two pair in the last two years, and now have a very intimate understanding of this shoe’s strong points and weak points. I’ve now had a chance to give the Ultra Raptor a test on a wide range of hiking trails, and am always amazed out how well they handle anything I can throw their way.

Men’s Ultra Raptor
Upper:
The Ultra Raptor has a very comfortable upper with lots of breathable mesh. This is really nice for those long and hot days on the trail, as I can still feel the breeze kissing my toes when I’m 20 miles into an adventure. The fit is precise through the heel and midfoot, which is something I like quite a bit. La Sportiva uses a leather-like overlay on the inside of the heel which creates a no-slip fit. This feels like it might create a little too much friction when you first try the Ultra Raptor on, but this feeling quickly goes away the second you start hiking. The outside of the heel uses a skeleton cage stabilizer for the heel counter.
The upper of the Ultra Raptor uses plastic overlays to comfortably wrap the midfoot and provide excellent lateral support. This lacing system is very secure and has never caused my foot to have any hot spots.
To keep the Ultra Raptor free from debris, a one piece overlay was stitched under these wraps, but over the tongue. This is a really nice design that keeps rocks and pebbles out of the shoe without adding any pressure points to the top of the foot.
The upper of the Ultra Raptor utilizes a rand that runs from heel to toe. At first I thought this would be uncomfortable and diminish breathability, but that hasn’t proven to be the case.
The only thing that I really don’t like about the upper of the Ultra Raptor is the shape of the toe box. It is very narrow. I’m usually a 12-12.5 in trail running shoes, but have to order this shoe in a size 13 to accommodate for the narrow width in the toe area. The materials used in the toebox are forgiving and haven’t caused any blistering or uncomfortable rubbing, but I’d still like to see the next version widen up a great deal here. The toe box has a nice rubber wrap for toe protection, which offers the right amount of burliness without getting in the way.
Midsole:
The La Sportiva Ultra Raptor has a 8mm drop with 30mm in the heel and 22mm in the forefoot. The cushioning for this shoe is just about perfect. I like shoes with a wide and flared heel for stability, and was a bit worried when I saw how narrow the heel was on the Ultra Raptor. So far, this has not caused any problems with me rolling my ankles.
La Sportiva uses MEMIex EVA throughout the entirety of the midsole, with a compressed EVA stone guard to act as a flexible rockplate. This midsole can do it all, and offers incredible protection over the toughest rocky trails we have here in Southern California. This is one of those shoes that leave my underfoot feeling fresh, even after walking for 20+ miles on jagged scree. There aren’t many shoes that give me this kind of comfort.
For added protection, control, and torsional rigidity, La Sportiva uses the Flex Transfer Shank in the arch of the midfoot, which is a part of the shoe’s Impact Brake System. The Impact Brake System sounds like a bit of a gimmicky marketing term for useless technology, but I can assure, it’s not! This shoe offers a great deal of control and precision when flying downhill. Downhill hiking can add a lot of stress to the joints of your legs, but these shoes seem to handle it better than most.
The only downside to the MEMlex EVA midsole from my experience is the way it wears down. Both pairs of my Ultra Raptors have worn down unevenly and in a pretty quick fashion. This could be entirely due to my walking gait, but it’s something I thought I should mention, as I’ve seen it mentioned in other reviews as well. On both of my pairs, the outside of each foot compresses much more than the inside, leaving my foot an ankle in a permanently supinated position. This begins to occur shortly after 100 miles on each pair, which is far sooner than most shoes I’ve worn. I think La Sportiva should use a more durable and less compressible EVA for this shoe. I know that would forfit a lot of the bounce and comfort of the MEMlex, but the added durability would be a nice tradeoff.
Outsole:
The outsoles on the Ultra Raptor are incredible, and quite possibly the most grippy outsole I’ve ever worn. Wet rock, wood, leaves, dust covered slab, slick slab, talus, scree, crushed gravel, you name it, this shoe will stick to it like glue. The trade-off you make with a soft and sticky outsole is durability, and that was the case with the Ultra Raptor as well. This is largely dependent on the types of trails you frequent, so keep in mind that I hike on some pretty nasty stuff with lot’s of sharp and jagged rocks. There aren’t too many shoes that make it past 200 miles on the arid range I call home. Still, compared to other shoes I’ve hiked in over the past two years, the Ultra Raptor has shown excessive wear the quickest. This doesn’t really impact it’s overall grip or performance right away, but my first pair was rendered just about useless after 150 miles.
The outsole of the Ultra Raptor uses the Frixion XF Green compound and not the Frixion AT Blue that is found on the Wildcat (a similar La Sportiva Model). In my experience, the Green is a stickier and softer compound that sticks to everything, but wears down a little quicker. The friction blue has great grip as well, but a little less than the Green. The Blue is a harder rubber compound which makes it last a little longer and makes the ride a little less bouncy underfoot. I think this might be one of the big reasons many hikers I see on the Pacific Crest Trail use the Wildcat and not too many wear the Ultra Raptor. That extra durability goes a long way.
The lug pattern on the Ultra Raptor’s full coverage outsole is very well designed, and as I mentioned before, sticks like glue to just about any surface. The Frixion Green oval shaped lugs compress underfoot giving great cushion and ground contact.
Closing Thoughts:
In conclusion, this is a great hiking shoe for all outdoor adventures. I’ve had a few issues with the durability of the midsole and outsole, but a lot of that has to do with the trails I’m using this shoe on. When it comes down to it, I’m on my second pair now, so clearly the functionality vs durability trade-off is one I’m willing to make.

Just bought a pair of these and have tested them on two shorter trails. I am still breaking them in and haven’t made a final decision. I did notice a bit of slippage in the heel on the last hike, but it didn’t seem to cause a hot spot or any blistering, so I’ll see how that fairs in the future. They do stick to everything, though wet rock was still a bit slick. I’m coming off a pair of Merrell Moab Ventilators after about 400 miles that I love, but needed something more breathable. Hoping these work out as good as those did.
Let me know how that goes. I’ve read a lot of nice things about the Ventilators, but like you, many have had problems with the breathability and weight. .
Taking a pair of these on the JMT and I’m wondering how quickly they will dry. Wondering if i need to take a water shoe for the water crossings. Great review and a great site.
They dry fairly quickly. The overlay in the midfoot retain a little water, but overall they do very well. I don’t think it would be worth the weight to haul around a water shoe for the few creek crossings on the JMT.
Awesome, thanks!
Got a size 43.5, my size in two other La sportiva’s that I own. So I went with that size in the Mutant. Way to small although lengthwise they were fine. So I got a 44. It fit great. However they have high arches and I got a hot spot on the arch of my right foot and the left foot arch didn’t feel good either. Unfortunately they are going back to the seller. I can’t criticize a shoe sinceI haven’t really worn that much because of fit issues. But my other La sportive’s were great so I’ll be buying a new pair of them in the future.
The Mutant can feel a bit more narrow in the arch and instep area. The more pronounced arch plays a large role in that. The new Akyra fits a lot more like the Ultra Raptor.
Drew, really appreciate your reviews. Some of the best I’ve found. I’m trying to decide between the Ultra Raptor and Akasha for a fastpacking trip in the Grand Canyon. (Have done a lot of trail running and backpacking. This will be first time trying to mix the two. I think the pack will be about 15 pounds.) Thanks!
Thanks, Mark. I prefer the Akasha. The outsole is more durable, the base is more stable, and the overall fit is much better for long days. YMMV.
I hiked the JMT solo in 2016 with a pair of these. Great pair of shoes. I’m old at 55, but still playing a lot of soccer and backpacking. I put in a some blue Superfeet as I have flat feet and my right dominant right foot is a weirder shape than than my left. They worked great! Giant toe box for me, really helped with no chafing, but the midsole held my foot in place. I walked thru a lot of creeks, when the boot wearing hikers were taking theirs off. Always dry with wool socks in a few miles. No blisters, no hot spots doing 15 miles/day. They were worn out though as I strolled into Lone Pine. Doing the PCT in a few years after retirement, I’d have a pair or two waiting at a resupply as the stitching was coming up and the treads were trashed, but the shoes were functional and could easily go another hundred depending on the trail. The laces suck, had some generics and I replaced the left side near MTR.
Thanks for the info, Russell!
The heel rubbed like crazy from day one – easy trails and on mountains. I only got maybe 30 miles in with them and couldn’t take much more. I tried taping and padding my heel with no help. I did get the 42 but need 42.5 according to the size chart but REI doesn’t sell that size for women.
Any recommendation on a different sportiva? The toe bumper was essential, rock guard was great and the grip was perfect on all terrains. I wonder if ordering a bigger size would help at all even tho the shoe doesn’t feel small anywhere. Heeeeellllppppp I need shoes 🙂
If you like the fit, feel, and ride of the Ultra Raptor, you should give the Akyra and Akasha a try. Both are available at most REIs.
Ultra Raptor 2 coming out! Can’t wait for your review!
Yes! I’m hoping to get my hands on a pair soon. I’m loving the Akasha II in the meantime.
