These are the cutest and the M size fits my women's sized 6 1/2 to 7 size foot. The only problem is I think one was defective as the squeaker doesn't work. The other works perfectly, so I figured it was just the pressure difference in my walking, but I took out the little bit that makes the noise and it was filled with sticky stuff. I tried to clean it out, but it still doesn't work. Other than that I love them. If the squeaker worked on both shoes, they would be perfect.
