A shoe including a solefor absorbing an impact of landing, an upperfor wrapping around an instep, and shoelace meansfor fitting the upperto the instep, the upperincluding: a main portionM covering a medial side surface, a lateral side surface, a toe, the instep and a back surface of a foot; a side edge portion having a plurality of first eyelets H; a first side panelcovering the medial side surface of the foot; and a second side panelcovering the lateral side surface of the foot, wherein each side panel includes: a tip portionhaving a second eyelet Hwhich is provided at a tip of the side panel and which the shoelace means passes through and engages with; a bottom portionattached to the main portion and/or the sole; and a middle portionarranged between the tip portion and the bottom portion so as to allow the tip portion to move in the front-back direction of the foot with respect to the bottom portion, wherein with at least one of the side panels, the middle portioncan stretch and shrink to increase a length from the tip portion to the bottom portion.

Shoe having lace fitting structure

A shoe having a sole, an upper including a first opening and a second opening, and shoelace means, the upper including: a first side edge portion having a plurality of first eyelets; a second side edge portion arranged between the plurality of first eyelets and having one or more second eyelets which the shoelace means engages with; a movable portion for allowing the second eyelet to move with respect to the first eyelets both in a transverse direction across the second opening and a diagonal front-back direction that is perpendicular to the transverse direction and is extending along the instep; and a main portion covering a medial side surface, a lateral side surface, a toe, the instep and a back surface of a foot, the main portion including the first side edge portion and excluding the second side edge portion and the movable portion; the second eyelet is relatively displaced via the movable portion with respect to the main portion both in the transverse direction and the diagonal front-back direction in response to a change in a direction of a resultant force between a first tensile force and a second tensile force acting upon the second side edge portion from a V-shaped portion of the shoelace means engaging with the second eyelet while transitioning from a flat-footed position to a heel-raised position.
