Kat crushing with flats then barefoot. 0-13 Kat crushes empty plastic bottles with her red ballet flats. Slowly crushing them with the toes of the shoe, then with the sole. You can see the muscles in her feet pulsate as she slowly crushes, lots of noises of the plastic cracking underneath her ballet shoes. 13-17 Slipping off her flats, she crushes barefoot, with black toe nail polish. Crushing facing forward, to the side, and showing off her soles, you can see her toes turning pink from crushing.
