US Patent 7493707 Low-cost disposable protective foot covering

Low-cost, single-use, disposable foot coverings and a method of using them to facilitate the protection of the feet of individuals who remove their shoes and would otherwise have to walk barefoot are disclosed. Assemblages of a number of such foot coverings (e.g., in the form of a continuous serrated roll of them) and methods of making the assemblages are also disclosed. The foot coverings may be particularly useful at security stations (e.g., in airports) where individuals must remove their shoes for inspection and then walk barefoot until their shoes are returned to them.
