Traction overshoes offer increased grip on slippery floors, turf, snow and ice. They help prevent slipping and tripping accidents and also protect shoes from rain, snow and salt damage. Traction overshoes come in two types. The first type fastens over shoes with hook-and-loop straps. The second type is a seamless, full-shoe design that is waterproof. The soles of both types have either deep PVC (polyvinyl chloride) cleats or metal studs that increase traction on slippery floors, snow and ice.
