I am an average size 8 and this shoe fits perfectly.  I didn't have the same slippage problem the first reviewer mentioned.  These are so cute and comfortable.  It's like wearing flip-flops, but polished and dressier.  I can wear these with slacks to the office as well as with jeans on the weekend.  Footbed is comfy and gives support similar to a regular Teva.  Love these!
