Customer Reviews

Comments: I love these shoes. I usually wear a 10 in most brands (brooks, nike, asics) but ordered an 11 in these because I read they run small. I want to wear them for a 50-miler and my feet tend to swell late in the race. They feel very comfortable right out of the box. My first run was a 10-mile trail run, followed by a 14-mile trail run the next day with no issues. I have also worn them on the roads a bit and they feel fine (unlike some trail shoes with large lugs and little cushioning). I think these will be my go to ultra shoe for all but the gnarliest of trails. My heel slips in almost all shoes, but not in these. These were the 6th pair of trail shoes (thank you runningwarehouse for free returns - I will never buy shoes anywear else) that I tried and the only pair that my heel was locked in, but had room in the toe box.
