I normally wear a size 8 in women's, so I ordered a size 6. It's a little snug so I can't wear them with thick socks, but I love these shoes! I've gotten many compliments on them. They were a bit stiff at first, and they chafed my heels. I had to wear bandaids on my heels for a while, but after wearing them for a week or two they no longer chafe and they feel a lot more comfortable.
