ABSTRACT:
An improved shoelace with an inner core of copper wire strands encased in a cover of clear polyvinylchloride, which is contained in an outer jacket or casing of polypropylene fiber. When the shoelace of the invention is threaded through a shoe and then tied into a bow, it retains its shape and does not become untied by itself. The bow may also twisted, turned, or otherwise shaped so as to further prevent the untying of the shoe by the fact of the retention of that shape by means of the inner core of twisted copper strands.
