Abstract
A loop for a shoelace utilizing an asymmetric pulley, including: a plurality of shoelace loops mounted to each of eyelet tabs of a shoe using respective rivets, wherein each of the shoelace loops includes: an asymmetric pulley having a pulley groove for guiding a shoelace without allowing the shoelace to be removed therefrom by itself and opposite circular side surfaces provided on opposite sides of the pulley groove, in which a diameter of a first one of the opposite side surfaces is larger than a diameter of a second one; a pulley holder having a structure suitable for sitting the pulley therein; and a rotating pin rotatably mounting the pulley to the pulley holder.
