I left my Crocs in my car for about a week and a half that I was off work and doing wedding stuff right before Anna's wedding, and moving, and etc. etc. When I finally got ready to go back to work, I went outside to get my Crocs and got quite a shock. One of them was in the floorboard, and one was on the ledge above the backseat, right in the window. Guess which one was where. I later went to the Crocs website and learned that extreme and prolonged heat will shrink your Crocs. Hmm. Good to know.
