These are so cute and I really wished that they worked better for me, I needed some cute flats for work. Sadly, the top of the heel support dug into my heel/ankle so badly within about 15 minutes of wearing them. They weren't too tight, they fit fine. it was just so rigid. There was nothing that I could do about making them more comfortable. Even those heel pads you can get from Foot Petals. Sad these didn't work.
