  • Device which fits over a shoe and method of use
    Patent number: 9775398
    Abstract: A device fits over a shoe to prevent contaminants from the shoe from soiling a support surface such as the carpet or floor of a home. The shoe has a toe and a heel. The device includes a front section which is shaped and dimensioned to receive the toe of the shoe, and a rear section which is shaped and dimensioned to receive the heel of the shoe. A center section is used to removably connect the front section to the rear section. The center section is fabricated from a resilient material so that it can be expanded to receive the shoe, and then will resiliently contract to grip the shoe.
