Ordered a pair of saltwater sandals on line and took a risk by not sizing up (as they didn't have any colours I liked in size up). They're pretty tight, too tight really, but I've read that they stretch a lot if you get them wet and wear them until they dry? Has anyone experienced this? I don't want to risk doing this unless I'm certain it'll make them fit me properly, as then I won't be able to return them!
