I wear a 7.5-8 depending on shoe, and I bought an 8. I have a slightly wider foot, and these ALMOST didn't work. I did keep them because they were so cheap! If you are a wide foot person, there aren't for you, they'll make an indent on the top of your foot. I do however like that at the clasp its elastic so they are easy to slip on and off. After wearing maybe 3 times, the tan color is already coming off the shoe just from wear and tear on concrete etc.
