Single eyelet laces with interlocking aglets and methods of lacing the same

A kit comprising a plurality of laces, including a first lace and a second lace, each of the first and second laces comprising (a) an elongate body;

• and (b) a toggle on at least one end of the elongate body that is rotatable from a first position in alignment with the elongate body to a second position that is transverse to the elongate body such that each of the first and second laces can be threaded through an eyelet of a shoe with the toggle in the first position and then rotated to the second position to maintain the lace threaded through the eyelet, wherein the respective toggles of the first and second laces comprise an end with a cut-away portion and an end with a tubular shape, wherein the end of each of the toggles with cut-away portion has an internal shape and curvature that is the same as an external shape and curvature of the end of each of the toggles with the tubular shape so as to facilitate interlocking between the end of the toggle with cut-away portion of the first lace and the end of the toggle with tubular shape of the second lace when the toggle of the first lace and the toggle of the second lace are threaded through adjacent eyelets of a shoe and in alignment with each other, the end of each of the toggles with cut-away portion being cut away along sufficient of its length to allow an interlocking between the toggles that prevents rotation of the toggles when interlocked.
