ABSTRACT:
An electrostatically dissipating shoe protects against building up of electrostatic charges by dissipating of such charges through controlled ohmic path leakage between foot and ground. The shoe outsole is formed of synthetic material of substantial resistivity, providing overall resistance across it of about 10.sup.6 -10.sup.8 ohms. A flexible dissipating strip of synthetic material treated to be slightly conductive (about 10.sup.5 ohm-cm) overlies the outsole and extends along a major portion of the shoe length beneath an insole, being secured to the insole by electrically conductive adhesive. At least a heel portion of the insole is apertured over the strip. A cushion layer and/or sock liner overlies the insole, being also of substantial resistivity (e.g., about 10.sup.5 ohm-cm), and secured by conductive adhesive, which also fills the apertures for providing a conductive path through them to the strip. The construction creates an ohmic path continuous between foot and ground having resistance of 10.sup.6 -10.sup.8 ohms. Various alternative shoe constructions utilizing these principles and features are disclosed.
