Something is REALLY off with Aya's shoes in this picture Given where the raised tengu-geta sole is placed, it looks like the toe bent over position she is in in this photo is the ONLY one her shoes would allow her feet to be in, so she'd have to have her toes bent over like that PERPETUALLY.
And if she COULD straighten out her feet, the shoes would be so long they'd be suitable only for a clown or Sideshow Bob.
