I usually wear a size 7, sometimes a 7.5...ordered a 7 and it was a little snug so would have to go up a size if I were to exchange them. The biggest problem is that the bottom sole is not going to be supportive enough for what I need it for, so I am going to return this product. I really think they are otherwise very comfortable, look to be well made, and are attractive, but don't seem good for walking on uneven or rocky surfaces.
