SHOE WITH IMPROVED HEEL FIT PERFORMANCE
First Claim
1. A shoe with an improved heel fit comprising:
- a main upper being continuous from a tip of a toe to side surfaces of a heel and covering the toe and a medial side and a lateral side of a foot;
a sub-upper formed by a separate member from the main upper, covering the heel in the main upper without covering a distal head of a metatarsal bone;
a shoelace for fitting the main upper and the sub-upper to the foot; and
a sole to which secured edge portions of the main upper and the sub-upper along lower edges thereof are secured, wherein;
the main upper includes a notch covered by a tongue, and first eyelet holes which are arranged in two rows along the notch and through which the shoelace passes;
the sub-upper includes portions covering a medial side surface and a lateral side surface of a talus bone, and a medial side surface, a lateral side surface and a back surface of a calcaneal bone, and is in contact with a surface of the foot on the side surfaces and the back surface;
the sub-upper includes a lower portion, and an upper portion above the lower portion, the lower portion being covered by the main upper;
a rear portion of the tongue and the upper portion of the sub-upper together form a mouth through which a leg extends in an upward direction when worn, and fit to the foot at the mouth;
the upper portion extends diagonally upward in a rearward direction from directly below medial and lateral malleoli so as to cover a lower portion of an Achilles tendon at a level above a lower end of the lateral malleolus;
the upper portion includes a front extension extending forward from directly below the medial and lateral malleoli past a front end of the calcaneal bone, wherein at least a portion of the front extension is covered by the main upper, and the upper portion including the front extension is unattached to the main upper;
the front extension includes an eyelet portion forming a second eyelet hole;
a through hole is formed on a medial side and on a lateral side of the main upper for allowing the eyelet portion to pass therethrough so that the second eyelet hole is exposed outside the main upper; and
in a state where the shoelace has been passed through the plurality of first and second eyelet holes and is exerting a fastening force, the eyelet portion is drawn toward a center of the foot by the fastening force from a portion of the shoelace near the second eyelet hole, and the eyelet portion bends as the eyelet portion engages with the main upper at the through hole, thereby changing a direction of the fastening force to pull the upper portion including the front extension toward a front side, while the main upper is drawn toward the center of the foot by the fastening force from a portion of the shoelace near one of the first eyelet holes that is posterior to the second eyelet hole, whereby a portion of the front extension that is covered by the main upper is pressed against an upper side surface of the foot, thereby fitting the upper portion of the sub-upper to the upper side surface of the foot.

Abstract
First eyelet holes are arranged in two rows along a notch and a shoelace 3 passes therethrough, and a sub-upper includes a front extension 2f. The front extension 2f includes an eyelet portion 24 forming a second eyelet hole. The eyelet portion 24 is drawn toward the center of the foot by the fastening force from a portion of the shoelace 3 near the second eyelet hole, and the eyelet portion 24 bends as it engages with a main upper 1 at a through hole, thereby changing the direction of the fastening force to pull the upper portion 2u including the front extension 2f toward a front side, while the main upper 1 is drawn toward the center of the foot by the fastening force from a portion of the shoelace 3 near one of the first eyelet holes that is posterior to the second eyelet hole, whereby a portion of the front extension 2f that is covered by the main upper 1 is pressed against the upper side surface of the foot, thereby fitting the upper portion of the sub-upper 2 to the upper side surface of the foot.
