Fits my vertically thin foot, size fit and med width. Very comfortable. There are some seams inside shoe that could rub a thicker foot. The sole is not slick and doesn't have rubber look on edges so it looks dressier. First wear I wore with sheer tights and walked a lot, some was at an almost jog.  No rubbing at heel, around top edge, and didn't  squish toes together. I'm very pleased with this little flat. Its simple and very attractive on the foot. I don't wear any shoe without tights, no show socks or something between my foot and shoe. (sandals the exception of course). I ordered and returned 2 other flats, different brand, both too large, my fault but even the correct size wouldn't fit a vertically thin foot.
