This is typically superb dipping shoeplay action by the Dippingdanglerpro. We took a walk to the local store - not a bad day so she wore her classic red single-strap Birkenstock Madrids. At first we see her walking with the sandals slapping away at her heels. I then managed to capture her candidly in the supermarket as she browsed the shelves. As usual, she dips whenever the opportunity arises - sometimes at virtually every step! See her gorgeous feet doing what comes so naturally.
