I've had my Sanuks for about a month and they seem to be shrinking. I'm not too thrilled about the fact that shoes that fit great out of the box now don't seem to have room for my toes anymore. They were really comfortable, but now I'm not sure if I should try stretching them out or be the guy who returns 1 month old & worn shoes to BC. Reviews were mixed about buying true to size, up, or down, so I went with true. If you're buying, I guess I'd say by up a size. I wear 11.5 in every other shoe I own, so I got 12s and now I wish I'd gone with 13s.
