In preparation for the upcoming audition season, I really want to make my feet look as good as they can in canvas ballet shoes (I wear the Capezio Juliets, I think). Since I have a rather low instep but decent arches, I want to create a more flattering look. I find that when I go on releve, the soles of the shoes don't mold to my arch, instead just creating a line from the ball of my feet to the heel; you can relatively see nothing of my arch at all. I've already tried sewing the elastics to wear the archiest part of my foot is, but nothing seems to be working. Does anybody have any tips?
