These are lightweight, flexible shoe covers designed for hygiene and protection—commonly used in medical, food service, or cleanroom environments. Made from smooth, matte-finish yellow plastic or polyethylene material, they feature a contoured U-shape to fit over footwear snugly, with perforated ventilation holes across the top surface for breathability and moisture management. The tapered heel and raised front edge ensure secure fit without slipping. Suitable for sizes 35–39 (EU), as indicated in the Chinese text overlay ('黄色小码 35-39码可用'). Ideal for temporary use in sterile settings, labs, kitchens, or during home renovations where floor protection is needed. Easy to slip on/off, disposable, and cost-effective. Not fashion footwear accessories but functional protective gear—distinct from decorative shoe charms or fashion overlays. Their minimalist design prioritizes utility over aesthetics, with no branding, logos, or embellishments visible.
