Rated 5 out of 5 by from Super comfy if not super durable I just used these for a 4 day backpacking trip in the grand canyon. I had a 35lbs pack and was scrambling over big rocks, sliding down gravel, and wading across rivers. These shoes were a dream on my feet. I didn't have any blisters or even hot spots. They had plenty of traction and I was very stable. I think this is mainly because the geometry of the shoes matches my foot very well. My toes are flat and wide and this shoe has plenty of width up there. Midway through the trip I switched up my lacing to a heel lock and they fit even better. My only complaint is that they showed lots of wear from the trip and the upper is beginning to fray in a few places. I imagine that I will need to replace these somewhat often but it will be worth it for the fit.

Rated 5 out of 5 by from Just what I needed The Olympus 2.0 provides the desired amount of cushioning I need along with the "foot shape" toe box to scramble up and run down the some of the steep trails in the Wasatch mountains. The new sole provides great traction as well. Ran a trail marathon over the weekend and they proved to be the ticket. Still too early to see how they wear. I recommend them to anyone who needs max cushioning and a larger toe box.

Rated 3 out of 5 by from Love them! I received these as a gift about 2 weeks ago. I wear a size 10 in every other shoe, maybe a 10.5 on occasion. With these I had to go up to a size 11.5 to get the best fit. I love the cushioning, the wide forefoot area, and the zero drop. My biggest issue is that I've only run about 26 trail miles (not a lot in 2 weeks) and the vibram soles are already wearing thin. These do stick to just about everything, even wet rock I've run down. Generally, in my experience there is a trade off between a softer sole and harder sole, which is durability. I thought they would last a little longer than this; especially for $150. I generally go thru trail runners every 6 months, but I don't think these will last that long. Let me be clear. I only wear my trail runners for running. They're not knock around shoes. If not for this lack of sole durability I would have given them a solid 5.

Rated 5 out of 5 by from Sizing is still small Quick caveat: despite Altra's effort to improve sizing, they still are under-sized. I'm normally a 10. Ordered an 11 and my toes were right against it. No big deal, just keep that in mind when ordering.

Rated 2 out of 5 by from Two major problems 1. Sizing is different than other models. This is my 3rd pair of Altras but the size is smaller. Order 1/2 size larger. 2. Serious manufacturing defect. The was large glob of very hard glue inside the shoe which dug in beneath my toe nail. Still these are great shoes. REI accepted return without a problem.

Rated 5 out of 5 by from I <3 this shoe. I have run about 100 miles in these shoes, and I really do love them. Yes, they run a little small, but I have gotten used to that. I ran in the Lone Peaks before these, and they were okay. There is something about the sound of the soles of these shoes on gravel and pavement that is awesome. The sole is very grippy on dirt trails and rocks.

Rated 3 out of 5 by from Save your money go Lone Peak I love my Lone Peak. I never felt that there was a breaking in period. After trying the Olympus for ~14 miles on the trails, I had to switch back to my Lone Peak. I'm not giving up on the Olympus but be ready for hot spots to develop. Plus, there's a little more heel movement than I'm comfort with.

Rated 2 out of 5 by from Very Comfortable These are probably the most comfortable trail runners I've ever worn. I love the max cushion, rock plate, open toe box and zero drop. However, on extreme descents (40 degree / rocky & sandy) I found them to be awful. Downhill grip is very poor and they often let go with no warning, basically becoming a super short pair of ski's.
