I ordered a size up. When I took these heels out of the box, I thought I wouldn't fit into them. I tried them on anyways and to my amazement, they fit, though very tight. After briefly wearing them in, they accommodated and now fit so perfectly that I walk for short periods around the house just to develop my poise in them. They boost my confidence because they put my femininity on a pedestal while making my legs look their sexiest. They'll be a big help in my next competition.
