Please note, Flat Out of Heels run true to size but when in doubt go a size UP especially if you are right in the middle. For example, if you wear a size 7.5 and sometimes a 7 you will wear a small, however if you sometimes wear a size 8 then you will need a size medium. The shoes do stretch and conform to fit your foot perfectly after a few wears. The elastic on the back allows for a snug fit so your Flat Outs will never fit loosely.
