I have to say, I love love love these inexpensive shoes so much that I bought last year and searched my order history to buy them again. I am between a 7-8, so ordered the 7/8 and they fit comfortably loose, usually wear a 7.5 in dress shoes my foot is of average width and a bit on the thin side, if that helps any. I wear these to work and when ever I need a decent dressy shoe without a heel. These offer no support what so ever, which I knew not to expect, they are extremely thin and flat, if you are looking for more cushion you can add some in there.
I found that they fit loosely, which I like, the stones stay on relatively well, over the year a few have fallen off but not enough to notice unless closely inspected, they are very light weight and add that little bit if dazzle to my outfits. they don't seem to show any water marks, or wear marks, don't hold dust or dirt.
I'm now ordering a new pair of the black and the teal.
