I normally wear a 7.5, but it only showed a 7 or an 8. I ordered a 7 b/c normally 8s are too big on me. I tried them on and they were really tight under the clear strap in the front. So I am sending them back and exchanging them for a 8. I'm hoping they work. They are cheaper here than on other sites, and I am only going to be wearing these once for right now.
