Disposable shoe covers are thin, slip-on protective coverings made from materials like polyethylene, polypropylene, or non-woven fabric that fit over shoes to prevent dirt, water, and contaminants from being tracked inside. They’re commonly used in hospitals, cleanrooms, construction sites, and homes during renovations or viewings where keeping floors clean matters. Most are elasticized at the ankle for a snug fit and are designed for single use before being tossed, making cleanup fast and hygienic.
