i notice that this happens when you buy shoes that had one on display and one in the box... my fave shoes are like that - one orange and one peach because the sun light had bleached it and also if one shoe ends up in the wash and the other doesn't

but no, i hadn't noticed it

[EDIT] haha i hadn't looked at the picture again before i posted this - i thought it was just like one faded one normal XD . . . and here i was thinking i was smart...
