A lace with two permanently attached protuberances or ferrules to control the distance the lace may move through a shoe's lacing system. The protuberances keep the lace symmetrically positioned between the left and right sides of the shoe's lacing flaps. This keeps the loose ends of the lace, also known as tying ends, which extend beyond the top of the shoe's lacing system, equal in length. The lace may be used on any laceable item in addition to shoes. |
