The top edge of the shoe is folded over, rather than under, so there's nothing scratching against your heel. They are so soft and so nice to walk in. Way better than flats! I am a 7.5 and I bought a 7 and they fit great! These are so nice for your feet. I thought the taupe was going to be more taupe, but looked rather tan, but the picture here is much more accurate colorwise than on shoebuy.com where I got them. Love these! Probably not good to wear in the rain but otherwise these are the shoes I wear!
