Natural Rubber slip over shoe and boot protective cover. Designed for environmental cleanup projects, chemical protection and many other applications. These are the original version of what is now typically called the hazmat or nuke boot. With the I.S.A herring bone sole tread design, you won’t have the rubber and sawdust waste issues that other brands have. Great for many applications including environmental cleanup projects, chemical protection, food processing plant workers, general industrial and manufacturing workers, manufacturing plant visitors and inspectors, home maintenance or service repair workers like electricians, plumbers and air conditioning and heating technicians or when washing cars, mowing the lawn.
