I bought these in the nude sand color in 2013 and theyve been the only flats that didn't rub my heal raw and had just enough sole to not kill my feet by the end of the day. Just purchased them in patent black, the right one rubs a little after 1 day, hope I can break them in. I usually wear a 9.5-10 and my foot is quite narrow. 9.5 M fits perfect. Not too much toe cleavage haha. The new style doesnt have the arch support padding like the old ones did but my foot is too narrow to feel it and as you can see my old nude flats in the same 9.5 M kind of widened out with wear. The cool fit means nothing to me. They feel warm.
