The present technology relates to novel conductive polymer rivets designed to allow a user to ground a shoe, including a sandal. They allow for easy installation into various types of shoes resulting in a comfortable, aesthetic and grounded shoe. The present technology also relates to kits incorporating such conductive polymer rivets with instructions for inserting such rivets into a shoe. The present technology further relates to methods of inserting such conductive polymer rivets into shoes. The present technology also relates to shoes with the present conductive polymer rivets inserted therein.

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.

The present invention provides a shoe structure for earth ground and static electricity discharge, which comprises a shoe and an inner sole provided inside the shoe, and the inner sole comprises: 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 (conductor); 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 conducted to the conduction unit, and is adapted to be grounded on the ground, and the present invention is a very useful invention for maintaining human health by providing 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. The ground unit (130) includes a copper plate (conductor) (111) and a coated plate (112) attached to one side of the copper plate (111), wherein the copper plate (111) of the ground unit (130) is coupled to the copper plate (111) of the ground connection unit (123) by a coupling means in a close contact manner. In this case, the coupling means is preferably the rivet 140, but a known fastening means such as a bolt and a nut may be used.

Electrically conductive vulcanised epoxidised natural rubber [ENR]-carbon black blends can be produced by using either internal mechanical mixing method or open milling method. These two methods are commercially friendly due to their practicability and high production rate. The addition of vulcanisation system, either sulfur or peroxide type does not affect the electrical properties of the vulcanised blends. All vulcanized blends prepared in this innovation show useful electrical properties with electrical volume resistances as low as the order of 10.sup.1 ohms. All these vulcanised blends also exhibit good mechanical properties with tensile strengths up to 26.0 MPa and Dunlop rebound resiliencies of 14.0% (i.e. high damping property). The black colour level of all these vulcanised blends is adjustable. As a result of good electrical and mechanical properties (especially high damping property), they have good potential to be used for antistatic footwear manufacturing and application.
