A shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces. The shock absorbing portion includes at least one three-dimensional structure body obtained by changing a shape of a unit structure body thickened based on a unit structure of a Schwartz P structure. The shape of the three-dimensional structure body in an unloaded state is a shape obtained by changing the shape of the unit structure so as to follow the shape change of the unit structure body, which is the regular hexahedron shaped space occupied by the unit structure body, into the trapezoidal space.

An upper includes an upper main body that covers an instep of a foot. A first region and a second region adjacent to the first region are formed in the upper main body. The upper main body includes: a first linear body provided across the first region and the second region or provided only in the second region; and a second linear body provided in the first region while avoiding the second region and having an end located at a boundary portion between the first region and the second region. The first linear body and the second linear body have mutually different stretchability.

A shoe sole which has a landing surface composed of three regions of a middle-sole region, a fore-sole region and a rear-sole region, and has a plurality of groove portions in the landing surface. The groove portions include: a first groove portion located in the fore-sole region, on a first imaginary line extending along the MP joint; a second groove portion located in the fore-sole region, on a second imaginary line extending along a line which connects a medial outer edge of the fore-sole region and a lateral outer edge of the middle-sole region with each other, in an area which is closer to a toe than to the first groove portion; and a third groove portion located in the rear-sole region, on a third imaginary line extending along a line which connects a medial outer edge of the rear-sole region and a lateral outer edge of the middle-sole region with each other.
