According to FreePatentsOnline, these protective accessories trace their origin to the disposable foot slipper patented by Olive G. France on Feb. 3, 1953. This invention led to related products including the sanitary shoe wrapper (August 1967), protective foot cover (March 1974), disposable protective shoe cover (April 1974) and slip resistant disposable shoe cover (July 1986).
