Fantastically comfortable shoe, with very little need to wear in. Fits foot in a very enclosing grip, so moves with foot very well with no slipping around. I'm going to be doing a lot of walking and running in these, I'm certain. Would be 5 stars if not for an annoying squeak I get on every step. Seems to be most prominent from my left heel. I really hope it dissipates soon, or I might be inclined to try to get them replaced for a pair that doesn't have the noise. As with most people, I found this to be a half size longer than expected. I was worried that going down a size would make them too narrow as I have relatively wide feet, but no, it fits perfectly.
