I ordered these in my usual size. Once I put them on, I immediately recognized that they were terribly uncomfortable before even standing or walking in them. The elastic band in back helps to pull the front thong portion deeper in between your toes- it's awful! I liked the construction and quality, so I ordered them a 1/2 size bigger, thinking that would lessen the pull. Nope, they're still painful, and there's about an extra inch of sole sticking out the back because they're too big for my feet. All in all, poor execution. Both pairs going back. I like how the other reviewer gave them 5 stars before even putting them on. Good luck with that!
