Many people use Crocs in ways they were not designed to be used!  Running and sports are not things that Crocs excel at.  Not many people realize the history and initial purpose in mind when Crocs were created. Crocs were created by a couple of Colorado natives who collaborated with a Canadian foam company on a shoe design.  They then created official "Crocs," which they intended to be used for boating, docks, and around the water. Active days and sporting are things best left to the sneaker department.  Lounging, boating, or running errands are better left to Crocs.
