Let me tell you these are the most comfortable sandals Ive ever purchased!! Like other reviewers have said these do run large in size and although some reviewers said order a whole size down or half size down, I decided to order half size down and they fit just right. Im a size 8.5 so I ordered size 8. There is a little wiggle room in the back of the sandal but I know for a fact had I ordered a 7 it would have been a tad bit small, I do have slightly wide feet and fair warning if you have really narrow feet these sandals could be too big for you. Theres nothing bad I can say about these sandals other than the sizing running a bit too big. I would definitely order these sandals again!!
