Abstract: A shock absorber includes a three-dimensional structure composed of a unit structure repeatedly, regularly and continuously arranged in at least one direction, the unit structure being a three-dimensional shape formed by a wall having an external shape defined by a pair of parallel planes or curved surfaces. When the unit structure occupies a cuboidal space representing a unit space and defined by mutually orthogonal three sides having a first side extending in an axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load and second and third sides each extending from one end of the first side in a direction orthogonal to the axial direction, and the first side has a length L1 and a longer one of the second and third sides has a length L2, the shock absorber satisfies 1.1≤L1/L2≤4.0.

Abstract: A shoe sole includes a resilient member, and has a bottom surface as a ground contact surface and a top surface. The resilient member has a three-dimensional shape formed by a wall having an outer shape defined by a pair of parallel flat or curved surfaces, and may buckle when the resilient member receives a compressive stress applied in a normal direction to the bottom surface. In the shoe sole, when a load is applied to the shoe sole in a gradually increasing manner such that a compressive stress is applied to the resilient member in the normal direction, the resilient member starts to buckle when a stress applied to the resilient member is within a range of 0.05 MPa or more and 0.55 MPa or less and a strain of the resilient member in the normal direction is within a range of 10% or more and 60% or less.

Abstract: A shoe sole includes a shock absorber that buckles when the shock absorber receives compressive force applied in a normal direction to a ground contact surface. When a load is applied to the shoe sole, the shock absorber starts to buckle in a state in which a stress occurring in the shock absorber is within a range from 0.15 MPa to 0.80 MPa and a strain of the shock absorber is within a range from 10% to 60%. When a time point at which a strain energy density of the shock absorber reaches 0.157 J/cm3 is defined as a specific time point, a maximum value of the stress occurring in the shock absorber until the specific time point is 0.80 MPa or less, and a tangential elastic modulus of the shock absorber at the specific time point is 5.00 MPa or less.

Abstract: A shoe includes an upper portion surrounding an internal space configured to accommodate a foot. The upper portion includes an inner foot outer surface of an inner foot portion, and an air sucking out portion from which air is capable of being sucked out from the internal space to outside of the shoe when a leg of a wearer of the shoe swings is disposed on the inner foot outer surface of the inner foot portion of the upper portion. The air sucking out portion extends in a direction which is slanted by a predetermined first angle with respect to a vertical direction when the shoe is placed on a horizontal plane and is recessed relative to the inner foot outer surface.

Abstract: A shock absorber includes a three-dimensional structure composed of a unit structure repeatedly, regularly and continuously arranged in at least one direction, the unit structure being a three-dimensional shape formed by a wall having an external shape defined by a pair of parallel planes or curved surfaces. In the shock absorber, a differently shaped portion which does not correspond to the wall defining the unit structure is locally provided in a shock absorbing region which is a region in which the three-dimensional structure has the unit structure disposed.
