A lacing system having multiple anchor types, i.e., interior anchors, end anchors, and dynamically adjustable anchors, that, in combination with parallel lacing technology, provide instant and reliable fastening for shoes, boots, and other articles of manufacture. The lace is threaded and anchored so that, a single arcuate pull on the movable fastener(s) causes the multiple lace segments to move through the eyelets of the shoe, and align in unison, so that the entire shoe opening contracts (or opens wide) simultaneously. The fastener(s) can be hook and loop, ratchet buckles, adjustable buckles, or cord locks. The laces are replaceable. The adjustable opening is customizable for different width feet providing “gross” adjustment. The fastener provides “fine” adjustment. Methods and diagrams are disclosed for threading, anchoring, and customizing the lacing, as well as for indicating that the lacing is correct. |

1. A lacing system used in combination with an article of apparel, wherein said article of apparel comprises:
(a) an adjustable opening defined by a first side, a second side, a top, and a bottom; wherein said adjustable opening defines a width extending from said first side to said second side, and wherein said adjustable opening has a fastened position and an unfastened position; (b) a vertical axis defined by said top and said bottom; wherein the relative positions; below, upward, downward, and top most; relate to said vertical axis; (c) a plurality of eyelets on said first side and a plurality of eyelets on said second side; wherein said plurality of eyelets on said first side is greater than said plurality of eyelets on said second side; and wherein said plurality of eyelets on said first side comprise at least five eyelets, and said plurality of eyelets on said second side comprise at least three eyelets; and wherein fewer eyelets on said second side is adapted to provide room on said second side for a fixed fastener; (d) and wherein four of said plurality of eyelets on said first side are located at the top most eyelets on said first side, and are at the top of said first side; and said fixed fastener is fixedly attached to said top of said second side, and said at least three eyelets on said second side are disposed below said fixed fastener; said lacing system comprising; (e) at least one lace having a first end and a second end; wherein at least one of said first end and said second end is used for lacing through said plurality of eyelets on said first side and said second side; (f) four lace segments formed from said at least one lace, said four lace segments having four top segments, at least three middle segments, and at least two bottom segments; (g) a movable fastener movably attached to said four top segments, wherein said four top segments extend from said movable fastener to the top four eyelets on said first side; (h) and wherein said at least three middle segments extend n at least three of said top four eyelets on said first side, to said at least three eyelets on said second side; and wherein said at least three middle segments traverse diagonally downward from said first side to said second side; and wherein one of said at least three middle segments is the top most segment in said adjustable opening, in said unfastened position; (i) a gap at said top of said adjustable opening in said unfastened position; wherein said gap is formed by said top most middle segment, said second side, and said top; and whereby said gap increases the width of said adjustable opening at said top to facilitate the insertion and removal of a body part from said article of apparel; (j) and wherein in said fastened position, said four top segments extend from said top four eyelets of said first side, to said fixed fastener on said top of said second side, thereby traversing said adjustable opening; and wherein one of said four top segments is the top most segment in said adjustable opening in said fastened position, and wherein at least two of said four top segments cover said gap at said top of said adjustable opening, and wherein at least one of said four top segments traverses diagonally upward from said first side to said second side; (k) at least one eyelet of said at least five eyelets, is disposed below said four top eyelets on said first side; and wherein at least one of said at least two bottom segments extend from at least one of said at least three eyelets on said second side, to said at least one eyelet on said first side, thereby traversing said adjustable opening; (l) and wherein one of said at least two bottom segments contains said first end, and another one of said at least two bottom segments contains said second end, at least one retainer; wherein said at least one retainer is located at said bottom said adjustable opening; and wherein said first end is anchored to said at least one retainer and said second end is anchored to said at least one retainer, thereby fixing the maximum width of said adjustable opening in said fastened position; (m) and wherein at least one of said first anchored end and said second anchored end is adjustable, and wherein said adjustable anchored end is anchored by one of an adjustable stopper and a cord-lock; thereby changing said maximum width of said adjustable opening in said fastened position, to customize said article of apparel; (n) and whereby pulling said movable fastener towards said fixed fastener causes contraction of said adjustable opening; and (o) said fixed fastener is engagable with said movable fastener to maintain said contraction of said adjustable opening in said fastened position. |
