  • Patent number: 7471497
    Abstract: The present invention provides a device that can be readily installed in any type of footwear, and that when installed enables a semi-continuous grounding path through the shoe of the wearer to an earthly source to dissipate static electricity. The present invention consists of a collection pad, an electrical path to a resistor, and continues that path to an earthly ground that prevents, or greatly reduces, electro static discharge (ESD) in personnel and their clothing when they are wearing shoes with insulative-soles. Alternatively a single resistor wire is employed to conduct static electricity to ground. This device is intended to increase the comfort level of the wearer of such shoes by eliminating, or greatly reducing the harmful and annoying effects of ESD without having any affect on the cosmetic appearance or the functionality of the shoe.
