An elastic shoelace includes a first end and a second end, an elongate elastic core, a sheath, and an elongate friction member. The elongate elastic core extends between the first and second ends of the elastic shoelace, and the sheath includes an outer surface and surrounds the elongate elastic core. The elongate friction member is disposed in the sheath, and at least a portion of the elongate friction member protrudes past the outer surface of the sheath.
