Sizing Notes
For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

Fantastic shoe, ignore the folks who size it wrong
1 year ago
This is a great do-everything shoe for me. Backpacking, running, hiking, scrambling. Well cushioned yet very stable. Perfect level of trail feel for me so my feet don't wear out (not a ton of feel despite the lack of a rock plate.) It breathes very well yet keeps dust out. Great for everything in Colorado and Utah up to low 5th class climbing. Very sticky soles and it edges decent. It's a bummer that this shoe gets lower ratings from people who never tried the right size. Ignore them. If you size this based on Euro sizing it's not far off, and sizes the same as other LS footwear. I'm normally a 45, in La Sportiva I'm 45.5. I do not have a narrow foot. It's average width and higher volume and this shoe feels great. It's worth noting La Sportiva is off a half size in their Euro to US conversion. 45.5 is a men's 12 according to them, but it's 11.5 everywhere else. Like all Europe-based brands you should buy based on the Euro size and not their conversion size.

Very well balanced shoe - great for everyone
1 year ago
I've had these for about 8 months and love em. They have done me well scrambling on the Front Range of Colorado, running on slick and rocky trails in NY/NJ, and on some muddy trails in Hawaii. They're very comfortable to run in and have enough stickiness for scrambles. Edging is decent enough and the lugs make for very good traction. Buying a second pair and highly recommend these. For the casual hiker they'd be more than sufficient for a hiking shoe, and more advanced trail runners/distance hikers/scramblers they are very much a "do everything shoe".

Love These
1 year ago
I bought about 8 different pair of trail runners for backpacking/hiking, and these were the ones that felt the most comfortable and fit my foot the best. Took them up in the San Jacinto’s and went off trail for 3-4 miles trudging over endless thorn bushes and massive downed pine trees, and these things were amazing.

Made to move in the mountains

These are shoes for serious mountain travelers and runners. Forget mushy midsoles and treads that are fashionable but dysfunctional when your fit hits the fan and your mission matters. Mutants are my shoes of choice when the mix is equal part trail, off-trail and scrambling. This shoe handles mud, dirt, scree, rock, slabs and snow like no other. Size up a half or whole because the unique ankle wrap, lacing and heel pocket keeps you in the sweet spot, without slosh or deformation.

Too short and too narrow!!!
4 months ago
Sizing is way off. I'm a size 11 in every shoe I own. 44.5 is the direct conversion by La Sportiva. My toes are touching the front. Also I have an average width foot and the sides are pushing in on my toes, causing my forefoot to fall asleep after standing in them for only 15 minutes. No way would I want to take these outside and go for a run!

Perfect Alpine Shoe. Solid on rugged terrain
11 months ago
Great high alpine shoe. Like with ANY piece of footwear, get yourself fitted or at least try on multiple sizes. You want around 1/2” of room past your longest toe in order to have proper room. Sportiva shoes having euro sizing allows for you to really perfect fit. I have a narrow foot so I had size down 1/2 size (from 44-1/2 to 44). The side lacing allows for you to really get these perfectly snug around your midfoot.

Sizing runs small
1 year ago
Sizing is a problem; runs small. My toes bang the front on downhills. The mens 43.5 is about a size 9 or 9.5 US.

Narrow Even When Sized Up
1 year ago
I sized up from a 11.5US to a 12US, which wasn't enough. The shoes are incredibly narrow and I could barely get them on. Had to return them because there's absolutely no way these would be comfortable even after a little bit of wear.

Waaay too tight. Size up at least a full size.
1 year ago
Waaay too tight. Size up at least a full size. Maybe more. I sized up a half size and I'm just sitting here and my foot feels like it is going numb and is super sore (I was barely able to get into the shoe) Tongue also seems like it would allow a ton of sand and pebbles in, as it is open down the outside edge (why?). Lastly it has really short laces.

Not Sized Well

I have been wearing La Sportiva for years. These shoes are just too tight, and I am wearing the right size. My toes have not recovered from one 5 mile run!
