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. |
