Abstract:
1. A shoe having a lace fitting structure, comprising: a sole for absorbing an impact of landing, an upper for wrapping around an instep, and shoelace means for fitting the upper to the instep, wherein the upper defines a first opening through which a leg comes out in an upward direction during wearing, and a second opening provided on a front of the first opening, the two openings being continuous with each other in a front-rear direction, the upper comprising: a main upper covering a medial side surface, a lateral side surface, a toe and a back surface of a foot; a plurality of first eyelets provided along a side edge of the second opening, wherein the shoelace means passes through and engages with the first eyelets, and the first eyelets include at least one of the first eyelets placed near the toe around the second opening and at least one of the first eyelets placed near an ankle around the second opening; a plurality of second eyelets provided along the side edge of the second opening, wherein the shoelace means passes through and engages with the second eyelets, and the second eyelets are placed between the at least one first eyelet near the toe around the second opening and the at least one first eyelet near the ankle around the second opening; a first side panel extending in an upward or diagonally upward direction along the medial side surface in a space inside the main upper so as to wrap around the medial side surface of the foot; a second side panel extending in the upward or diagonally upward direction along the lateral side surface in the space inside the main upper so as to wrap around the lateral side surface of the foot; and a third eyelet provided at a tip of each of the first and second side panels, wherein the shoelace means passes through and engages with the third eyelet, wherein: at least an upper portion of each of the side panels including an area thereof where the third eyelet is provided is unattached to the main upper; and a frictional force between the shoelace means and the second eyelets is smaller than a frictional force between the shoelace means and the first eyelets, the shoelace means including: a first portion passing through the first and second eyelets so as to repeatedly reciprocate between the medial side surface and the lateral side surface without passing through the third eyelets, thereby narrowing the second opening in a foot breadth direction and fitting the main upper to the foot; and a second portion passes through from the at least one first eyelet near the toe around the second opening to the third eyelet of each of the side panels without passing through the second eyelets and further through the at least one first eyelet near the ankle around the second opening, thereby fitting the first and second side panels to the medial and lateral side surfaces of the foot.
