Easily adjustable, elastic D-ring assembly allows for flex during walking while minimizing particulation and sloughing. The D-ring features a tear-resistant, dual-layer, rubber cup with a black conductive outer layer and a light blue, non-marring, inner scrim that prevents carbon marks on shoes. A conductive, nylon polyester, grounding strap with a built-in 1MW resistor provides body-to-ground contact on both sides of the foot.
