It’s the iconic clog that started a comfort revolution around the worldThe irreverent go-to comfort shoe that you're sure to fall deeper in love with day after day. Crocs Classic Clogs offer lightweight Iconic Crocs Comfort. All Crocs™ shoes are uniquely designed and manufactured using our proprietary closed-cell resin, Croslite™, a technology that gives each pair of shoes the soft, comfortable, lightweight and non-marking qualities that Crocs™ wearers know and love. Heat: do not expose your Crocs™ shoes to extreme heat or intense sunlight for an extended period of time. Due to the unique nature of the Crocs™ PCCR material, high temperatures may cause them to warp. Crocs shoes should solely be hand washed. If the model features a lining, it is recommended to put the lining in a mesh fabric or use a delicate cycle (of up to 30 °) if you machine wash. Cleaning your Crocs using the washing machine is at your own risk
