Abstract
An electrostatic dissipative footwear comprises a conductive insole and a conductive outsole spaced by a non-conductive mid sole. An electronic device extends through the mid sole for connecting the insole and the outsole in electrically conductive relationship. The electronic device includes a resistor for precisely controlling current flow between the insole and the outsole, and an active electrical device, such as a fuse, for protecting the wearer against electrical shocks.
