Abstract:
1. An elastic shoelace for a shoe, comprising: a first end and a second end; an elongate elastic core extending between the first and second ends; a sheath surrounding the elongate elastic core, the sheath having an outer surface; and an elongate friction member disposed in the sheath, wherein at least a portion of the elongate friction member protrudes past the outer surface of the sheath, wherein the elongate friction member is fabricated from a material having a greater coefficient of friction than the material from which the sheath is fabricated, wherein the elongate friction member is disposed around the core in a helical manner, and wherein a helical groove is defined between adjacent segments of the elongate friction member such that when two portions of the shoelace are laced through the shoe and overlap, a segment of the groove of the first portion retains a segment of the elongate friction member of the second, overlapping portion of the friction member.
