Trimaco E-Z Floor Guards fit any shoe size and works by simply placing a sheet of adhesive plastic film on the bottom of your shoe or boot to avoid tracking dirt and debris into a home or jobsite. Simply step, pull and tear. Eliminates the need to bend over and struggle to apply like traditional shoe covers. Less waste than regular covers. The Starter Kit includes 1 pod & 1 roll of film – up to 250 pairs.
