Our SC1207 C disposable ESD shoe covers with skid resistant bottoms are made from two (2) pieces of heavy-weight 1.25oz (40 gm) polypropylene and that provides durability and long life. The disposable ESD shoe covers work well with most common shoes and boot but also work well when worn inside laundered cleanroom boot covers such as our TX4000 ESD Soft Sole Boots. The surged-seam inside shoe cover design features an elastic opening that fits most regular shoe styles with a secure fit. A full length non-woven conductive carbon grounding ribbon is added to the bottom of our ESD Shoe Covers to remove the static from personnel. The grounding ribbon provides adequate length for body contact when worn with most shoe styles. The conductive strip provides a ground path for the operator to remain static free when used with dissipative or conductive floors / mats.
