About a decade ago, sightings of odd-looking clogs suddenly began popping up everywhere. Brightly colored and clunky, the clogs didn't look or feel quite like other footwear. Some people were puzzled by them - were they plastic or rubber? What were those holes for? And where should you wear them, anyway? Others were charmed and intrigued. Crocs, made by the company of the same name, proved to be a new category of footwear. Constructed from a proprietary closed-cell resin material called Croslite (which is neither plastic nor rubber), they are soft, lightweight and odor-resistant, and their soles conform to the shape of a wearer's foot. They were originally designed as boating shoes, but purchasers - many of whom swore Crocs were the most comfortable shoes they'd ever worn - took them out into the streets, to the beach and to many other casual occasions.
