Weight Room/Cardio - Why do I have to wear closed-toe athletic shoes?

Closed-toe shoes are required to protect the users’ feet from equipment that may be dropped (dumbbells, weight plates).  Boots and heels can damage the equipment and weight room flooring and are not designed for use during exercise.  Stretching/exercise without shoes is allowed in the fourth floor stretching area only, as this area is free of weights and other potential hazards.
