I absolutely love these shoes.  Unfortunately, the keys hanging from the back when I wore them.  I think it was a result of my foot on the pedal and my heel on the floor of the car.  It just couldn't withstand the action.  The patent leather also ripped on one of the shoes quite early, so I don't get to wear these.  They are definitely one of my favorite shoes, and it's sad that they are unwearable so soon after purchase.
