Crocs Classic Lined Clog

While the outer shell is made entirely of Croslite foam, which is fully waterproof, the fuzzy inner lining is not. If the lining gets wet, it takes a long time to dry, so they are best worn as indoor slippers or casual outdoor shoes in dry weather.

The integrated lining is made from a plush, soft textile material designed specifically to trap heat. Some variations of these lined Crocs feature a synthetic fleece lining for enhanced warmth and comfort.

Unlike some other models that feature removable straps, the liner in the Classic Lined Clog is permanently attached inside the shoe. To clean them, you must gently hand-wash the liner with mild soap and cold water while it remains in the clog.

Because the lining takes up extra space inside the shoe, many people find that the Lined Classic Clogs fit slightly tighter than the unlined versions. If you are between sizes, Crocs often recommends sizing up to accommodate the inner fleece material.
