Introducing the Classic Platform, featuring a heightened, contoured outsole that supports the upper you know and love with a slimmer, sleeker look — but there’s more. The customizable backstrap also holds Jibbitz charms, so you can personalize your look even more. When you’re in the mood for a little extra boost, style it up with the Classic Platform. 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.
