"I wear a 7.5 to an 8 depending on the shoes. I ordered a size 38 in these and they fit great even with a little room if your foot is slightly larger. I love the fact that you can adjust the buckles as needed. I also love the colors of these. I am very very pleased and will be ordering more. I actually have another order coming in another color, there were only 3 left so I figured I would grab them and return if I wasn't happy, but I am so I'm keeping them. I was also very happy when they arrived mluch sooner than expected, 4 days earlier."
