a lace closure system may include a low friction guide that defines the turning radius and direction of a lace which , though tension , pulls two or more panels toward each other . the lace closure system may include a fixator that defines a slot into which the lace is led , containing multiple engagement surfaces that , when the lace is wrapped into the slot , serve to engage the lace preventing unwanted loosening . the lace closure system may include a ring onto which the lace is attached , to assist in applying manual tension to the lace . the ring may be shaped and sized to removably attach to an outer perimeter of the fixator after excess lace has been wrapped into the slot .
