All Crocs™ shoes are uniquely crafted from our patented Croslite™ closed-cell resin compound. This technology makes each shoe as supple, comfortable, colorfast and lightweight as Crocs™ connoisseurs have come to expect and love. Please do not expose your Crocs™ to extreme heat or intense sunlight. High temperatures can damage the Crocs™ PCCR material due to its special properties. Crocs should only be hand washed. Products with fur inserts can be washed in the washing machine at 30 degrees, although hand washing is also preferable here. The fur should be placed in a washing net or a gentler wash cycle must be selected. However, washing the fur in the washing machine is at your own risk.
