Hm, I could see this as just an old pair of men's oxfords with the laces taken out. The bigger picture is, how does she feel comfortable wearing these used shoes with no socks! Maybe I am just a germaphobe, but your feet sweat a LOT and your shoes just absorb all the sweat. I certainly wouldn't want some old man's sweat mingling with mine...ugh.
Whining aside, I love her style! She is fantastic.
