Warm And Fuzzy Feelings Inside. Kids love 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. They're great as slippers, yet capable outdoors, too. Croslite foam construction keeps them light and easy to wear. The pivoting heel strap gives kids a secure fit, or push it forward for an easy-on option.
