ABSTRACT:
The object of the invention is to provide a shoe sole which prevents the build up of static electricity to the degree that a shock occurs when a shoe is worn while walking across a floor covering such as a carpet. Electrically conductive elements in the shoe sole are unnecessary. Alteration of the carpet is unnecessary. A build up of static electric charge between the shoe sole and the floor covering is prevented when the sole has a bottom portion made from substantially the same material as the surface of the floor covering.
Shoe (1) having sole (2) is used for walking across floor covering (4). The bottom portion (3) of sole (2) is made from substantially the same material as floor covering surface (5). The bottom portion (3) may be a coating which may be brushed or sprayed on. Bottom portion (3) may also be a film material which adheres to the remainder of sole (2) by means of a pressure sensitive adhesive. A piece of floor covering (4) may be fixed to the sole (2) by means of an adhesive on the base (6) of the floor covering (4). In this way, the floor covering surface (5a) of the piece serves and the bottom portion (3) of the sole (2).
For use on a nylon floor covering, a shoe sole may be coated with a nylon film obtained by using a nylon latex dispersion.
