Elastic tops stretch to accommodate feet and keep the blue McKesson shoe covers in place. The durable, spunbonded material resists fluids, keeping feet dry. Non-skid strips on the soles of these anti-slip shoe covers help prevent falls and slips. The covers allow airflow for cooling comfort. Skid-resistant shoe covers are single-use and disposable to prevent cross-contamination. They fit over most footwear and offer full coverage. CAUTION: FLOORS MAY BE SLIPPERY. PERSONNEL WHO WEAR SHOE COVERS SHOULD BE AWARE THAT A RISK OF SLIPPAGE EXISTS, EVEN WITH NON-SKID STRIPS, AND SHOULD TAKE PRECAUTIONS TO AVOID MISUSE OF SHOE COVERS.
