Warm And Fuzzy Feelings Inside. Everybody loves the comfort of the Crocs Classic Clog — and now there’s a toasty lined version to keep the feeling going all season. The soft, fuzzy liner adds to the cushion and comfort, indoors or out. Great as a slipper, yet capable to run errands, too. Croslite foam construction keeps them light and easy to wear. The pivoting heel strap gives you a secure fit, or push it forward to just step in and go.
