I absolutely love these because they are so sweet and pretty. I like being a girly girl. Overall good quality but like others I did experience them slipping off my heels. The slippers are knitted and if you're aomewhat handy with a darning needle, thread up some shirring elastic and stitch it throught the top. Worked like a charm, no more slipping off slippers! I mostly plan to use these for travel as they are not really deaigned to be worn every day, all day. They do not hve any support either. Mostly for cozy feet and looks! But that's what I bought them for so I'm good with that. :)
