Claim:
1. A lace fitting structure in combination with a shoe having an upper, said upper having a medial side portion and a lateral side portion, said upper configured to wrap around an instep of a foot of a wearer, said combination comprising: said medial side portion configured to cover medial side surfaces of the instep and a big toe; said lateral side portion configured to cover lateral side surfaces of the instep and a little toe; a first shoelace configured to be placed to extend in a longitudinal direction of the shoe along edge portions of the medial side portion and the lateral side portion, and configured to be anterior to a top-line through which the foot is inserted into the upper, the first shoelace engaged with the medial side portion at a plurality of locations and engaged with the lateral side portion at a plurality of locations; a placement structure configured to place a first portion of the first shoelace on said medial side portion of the shoe anterior to the top-line so that the first portion is exposed in a plurality of medial exposed areas that are separated from one another in the longitudinal direction, the placement structure configured to place a second portion of the first shoelace on said lateral side portion of the foot anterior to the top-line so that the second portion is exposed in a plurality of lateral exposed areas that are separated from one another in the longitudinal direction; and a second shoelace configured to be engaged, in a transverse direction of the shoe, with the first shoelace in the plurality of medial and lateral exposed areas so as to bring the medial side portion and the lateral side portion closer to each other, wherein a length of each of the plurality of medial exposed areas and a length of each of the plurality of lateral exposed areas in the longitudinal direction are greater than a height of the second shoelace and a width of the second shoelace, the placement structure comprises: three or more insertion parts placed along each of the edge portions of the medial side portion and the lateral side portion, the three or more insertion parts being pierced therethrough in the longitudinal direction, and the first shoelace being inserted through the three or more insertion parts so as to be movable in the longitudinal direction, one exposed area of the plurality of medial exposed areas being defined between one pair of insertion parts of the three or more insertion parts, the one pair of insertion parts being placed along the edge portion of the medial side portion and adjacent to each other in the longitudinal direction, another exposed area of the plurality of medial exposed areas being defined between another pair of insertion parts of the three or more insertion parts, the other pair of insertion parts being placed along the edge portion of the medial side portion and adjacent to each other in the longitudinal direction, one exposed area of the plurality of lateral exposed areas being defined between one pair of insertion parts of the three or more insertion parts, the pair of insertion parts being placed along the edge portion of the lateral side portion and adjacent to each other in the longitudinal direction, another exposed area of the plurality of lateral exposed areas being defined between another pair of insertion parts of the three or more insertion parts, the other pair of insertion parts being placed along the edge portion of the lateral side portion and adjacent to each other in the longitudinal direction; secured portions for securing end portions of the first shoelace at least in the medial side portion and the lateral side portion; the medial side portion and the lateral side portion each include at least one through hole which is running through the medial side portion or the lateral side portion in a direction of the height and through which the second shoelace is inserted; the at least one through hole in each of the medial side portion and the lateral side portion is located posterior to a most posterior insertion part of the three or more insertion parts and posterior to the secured portion in each of the medial and lateral side portions; the second shoe lace is in contact with a part of an outer surface of the medial side portion and a part of an inner surface of the medial side portion, the at least one through hole is placed more medially than the part of the outer surface and the part of the inner surface of the medial side portion; the second shoe lace contacts a part of an outer surface of the lateral side portion and a part of an inner surface of the lateral side portion, the at least one through hole is placed more laterally than the part of the outer surface and the part of the inner surface of the lateral side portion; the second shoe lace is engaged with an edge of the at least one through hole in the medial side portion; and the second shoe lace is engaged with an edge of the at least one through hole in the lateral side portion, and wherein the upper comprises: a stretchable member that is configured to cover the medial side surface and the lateral side surface of the instep of the shoe in an area anterior to the most posterior insertion part, the stretchable member being stretchable in the longitudinal direction and the transverse direction; a non-stretchable member that is attached to a surface of the stretchable member, is less stretchable than the stretchable member, and forms a portion of the medial side portion and the lateral side portion; a plurality of protruding portions of the non-stretchable member configured to project toward a center of the instep of the shoe, the protruding portions being provided by a wave-shape formation of the edge portions of the non-stretchable member in the medial side portion and the lateral side portion; and a soft portion formed by the stretchable member between protruding portions adjacent to each other, which is not covered by the non-stretchable member and in which the stretchable member is exposed, wherein the insertion parts are provided at the edge portions of the protruding portions.
