LOve them! I am typically a 9.5 but sometimes a 9 depending on the brand. I ordered a 9 thinking because they are plastic, they would stretch so I didn't want a 9.5 and have them stretch and get too big. Well, 9 came and they were too small. Sent them back and got a 9.5. They fit perfectly. I wear them often! (Only had them about 3 weeks but I have worn them to work at least 8 times, then out and about) they have not stretched at all and they are surprisingly comfortable and of course adorable. Everyone asks me about them! Got them for $11 and they remind me when I was a kid. It's fun to have jelly shoes!
