Love these sandals! I ordered a 10, but I usually wear a 9.5. I can tell a 9.5 would have fit better as far as strap length, but they still fit well, so it's okay. They're very comfortable too, it only took a day to wear them in. They don't rub or scratch your foot the wrong way at all, I think you could go awhile without getting blisters. I have a wider foot and noticed these are a bit too narrow for me though. I would have liked a wider size option. They aren't abnormally slim shoes though at all! They still fit well because I ordered half a size up and again, my foot is just wide, so if you have a more normal width foot I think they would fit perfectly. The colors are so cute too! Very happy with them overall, would buy again if I needed to!
