Has anyone ever added a strap to a pair of shoes? I want to wear flats, but I find that the "barely covering the toes" style flats that are in style right now, don't stay on my feet very well. I was thinking about taking a basic pair of white flats and adding a "mary jane" strap (i.e. an inch or so above where the toe covers) I've got a pair of brown shoes in that style that I love. Obviously sewing would be the best way but I think that superglue would work too. Anyone ever done something like this? Do you think this would work?
