Great shoes. Can wear a new pair on a 10 mile run right out of the box. My only complaint is that the light weight soles wear through the toe ridiculously fast. I run 25 miles a week on asphalt and the first pair wore through in under a month. You might blame my running style except it never happened prior to switching to these shoes. I tossed the first pair (painful to do) and bought another which had the same problem. I tried some other styles but love the fit of these so much, I resorted to a $3 purchase of Shoe Goo to repair the sole and they have been fantastic ever since. My husband got a pair and ran a half marathon with me without the slightest break in and he loved them as well. I Shoe Gooed his before they hit the ground. Guess I will just keep the Shoe Goo handy and continue running with happy feet
