I was worried at first about these shoes because normally I am a size 7 1/2 but I had to order an 8. When I first put them on they were a little bit and I thought that as I walked they would slip off but I did not have this problem at all. These shoes work as like mini suction cups to your feet and give you a perfect fit. They are VERY comfortable and look very cute. I am glad I bought these and will continue to buy them in the future as well.
