I don't like plastic shoes, either, but I'm not sure what that has to do with Crocs.
all crocs brand shoes feature crocs' proprietary closed-cell resin, croslite, which represents a substantial innovation in footwear. the croslite material enables us to produce soft, comfortable, lightweight, superior-gripping, non-marking and odor resistant shoes. these unique elements make crocs footwear ideal for casual wear, as well as for professional and recreational uses.
Enjoy your keens.
