I normally wear 5.5 or 6 depends on the brand. After reading reviews I decided to go with the smaller end of my usual size. The shoes turned out to be longer than expected, however because it was designed with a narrowed front to make your feet look slim, the overall fit is fine. The bigger problem though, is that my right foot's arch seems to be a little higher than the left and I could not wear sock while wearing this shoes. The top of the shoes is not stretchable so the rim leaves a red mark on my right arch which is not comfortable.
