Helps maintain a cleaner room and environment. Shoe covers prevent tracking of substances around the building or workspace, which could otherwise damage flooring, pose as a fall hazard, or impair the sterility and cleanliness of the rooms. Even the spread of ordinary dirt and grime can be prevented by contractors such as electricians and plumbers when walking in and out of a customer's home with the help of disposable shoe covers. http://www.hbmurs.com/disposable-shoe-cover/
