I usually wear a wide shoe in either 9 1/2 or 10 wide, but this shoe didn't come in wide. So I ordered the 10 1/2 medium, and it fits perfectly. The shoe runs a little short, so it gave me enough width without being too long. I liked the fit so much I'm going to order it in another color. Also, the shoe is very comfortable. It's dressy in the beige with gold insets. Enjoy!
