For use in fluid-intensive conditions, Cardinal Health™ Critical Zone® shoe covers are made of durable polypropylene fabric that meets ASTM F1670 and ASTM F1671. Patented separate elastic band at the ankle minimizes the chance of fluid strike-through by eliminating pinholes caused by stitched-in elastic. Bound elastic seams at the foot reinforce fluid protection and adjust for a customized fit. Foam strips provide anti-skid protection and assist in donning orientation. Cardinal Health™ Critical Zone® shoe covers offer protection in the shoe area.
