Converse makes some of the world's BEST athletic-style safety shoes, and the On Line cross trainer is no exception! This shoe is rated as electro-static dissipative (ESD), so it will allow static electricity to be dissipated from your body into the floor surface, preventing build-up that could otherwise harm sensitive electronics and computer equipment. Also includes leather and mesh uppers, sweat-wicking tailex lining, removable EVA cushion insert and midsole, and a dual-density slip-, oil-, heat-, abrasion-, metal chip-, and chemical-resistant rubber outsole. 100% non-metallic and airport security-friendly. Color: Grey with silver and purple trim.
