This shoe was great, I've just gotten into rock climbing but am excelling quickly. This shoe can handle a lot. It stretched ALOT, Like 1 1/2 sizes. But if you buy big then there shouldn't be a problem. My shoe did have a problem with it early on, but it was a manufacturing mistake with that shoe individually. am in the process of sending it back now. Don't know how ill have to wait for it to get back to climb.
