I went by the other reviews and ordered a size down. I normally wear a 10 and ordered 9-1/2. However, I just recently had to wear orthotics in my heels, so they were way too tight. The toe bar area is somewhat narrow also. I'm not sure if I'll try another size or not (sigh), as I don't want to have to send them back also, but they are cute shoes. I have other Earth shoes and love them.
