Crocs, Inc. is a shoe manufacturer founded by Scott Seamans, Lyndon "Duke" Hanson, and George Boedecker, Jr. — to produce and distribute a foam clog design acquired from a Quebec company called Foam Creations. The shoe was originally developed as a boating shoe. The first model produced by Crocs, the Beach, was unveiled in 2002 at the Ft. Lauderdale Boat Show in Florida, and sold out the 200 pairs produced at that time. Crocs was the title sponsor of the Association of Volleyball Professionals (AVP) Tour from 2006 through the 2009 season. In June 2004, Crocs purchased Foam Creations and their manufacturing operations to secure exclusive rights to the proprietary foam resin called Croslite. Croslite is a closed cell resin. The foam forms itself to a wearers feet and offers purported medical benefits, according to a number of podiatrists. Crocs holds one patent covering various utility aspects of its footwear, U.S. Patent No. 6993858 B2 issued February 7, 2006, and three design patents covering various ornamental aspects, U.S. Patent Nos. D517788, D517789, and D517790 issued on March 28, 2006.
