I really like these sandals I normally wear and 8 in crocs how ever based on some of the other reviews I read I took their advice and ordered a size up and they fit perfectly. I have fat squatty little feet so finding sandals like these that fit well is fantastic. I will say the little heel tab that sticks up in the back at the end of the day started to annoy my heel but honestly it was only at the end of the day and it did not leave a mark or anything. If you have a sensitive heel this may not work for you.
