So I recently got some Manolo Blahnik Mary Janes in black patent leather. Was super excited as these are GORGEOUS...but after wearing them the first time, there developed this HUGE deep fold all across the right toe, but not the left. Is that normal? Why only one foot and not the other? The shoes are so ugly now that I really don't want to wear them. What gives? A Neiman's rep told me it sounds like they're defective and I should send them back, and their returns dept will make the decision as to whether they are or not. What have your experiences been w/patent leather?
