Provided is a shoe structure for earth ground and static electricity discharge, which includes a shoe and an inner sole provided inside the shoe, and the inner sole includes: a base plate; a foot contact plate which is adhered to the upper surface of the base plate, and is made of a copper plate; a conduction unit which extends from both sides or the rear of the foot contact plate, and is exposed above an ankle support unit in order to allow a ground unit to be connected; and a ground unit which is connected so as to be electrically connected to the conduction unit, and is adapted to be grounded on the ground, and a structure capable of charging earth energy through an earthing, and discharging static electricity generated inside and outside the human body rapidly and completely to the outside of the body.

A dustproof work shoe using recycled PET, includes: an outsole made of a conductive rubber portion; and an insole being laid on the top of the outsole and having electrical conductivity. The insole is made using a nickel-plated copper fabric in combination with a carbon-graphene yarn and provided in the bottom of the shoe that comes into contact with the foot. The insole is made of recycled PET.

This document discloses antistatic shoe insoles that include a flexible foam layer and antistatic filaments of textile material interspersed throughout the foam layer and extending passed or exposed at the surface of the shoe insole and methods of making such an antistatic shoe insole. The antistatic filaments are needle punched through the foam layer. The antistatic filaments may be any suitable antistatic material blended with any felt fiber such as wool fiber, cotton fiber, polyester fiber, or the like.

The article of footwear for grounding the human body to earth includes an upper portion; a sole having an outer sole face distal from a user and an inner sole face proximate to the user; one or more electrically conductive portions which extend through the sole from the outer sole face to the inner sole face; and an electrically conductive layer which extends over a portion of the inner sole face and being configured to make conductive contact with the foot of the human body. The sole includes a blade portion.
