I adore these shoes. They do run a bit big but once you know that you can order the correct size! I usually wear a 9 but I can wear an 8 1/2 in these shoes. I might even be able to go down another 1/2 size but I am comfortable with the way they feel and there is room for socks or whatever. I don't know what the whatever is, specifically, but there is a little room for it.
