Adults' Crocs Classic Clogs Embrace your comfort and casual style wearing the Crocs Classic Clogs! These lightweight clogs are constructed from durable Croslite material with an easy slip-on design and optional heel strap. Please note Crocs shoes may be one of three different fit types: Roomy, Relaxed, or Standard fit. This Classic Clog has a Roomy fit. Roomy provides generous room in both width and length. If you typically wear a half size, it is recommended to order down a half size (i.e. Size 8.5 should order a size 8 in this shoe).
