These are super cute. I usually wear between a 6 and 6.5 and I got these in a 6.5 and they definitely feel more like a 7 in length. So I'd say they run a half a size big. I'm keeping mine because I put an insole in them and so the bigger size works. They are comfortable but there is no arch support at all so if you like support I recommend putting an insole in them because they are more comfortable that way for a high arch!
