Abstract
The present invention provides a shock absorbing device for a shoe sole in a rear foot part which can restrain the inclination of the foot toward the medial side while absorbing the shock of landing on the lateral side of the foot. A shock absorbing device for a shoe sole in a rear foot part according to the present invention, includes: a support element M; deformation elementsdisposed below the support element, the deformation elements deforming to be compressed vertically at landing; and outer sole elementscontacting a ground at landing, each outer sole element being joined to a bottom surface of the respective deformation element. Both the deformation elementsand the outer sole elementsare substantially separated in a medial-lateral direction in the rear foot part to be arranged at least three regions of the rear foot part. A quotient obtained by dividing an area of a bottom surface of the support element M by an area of bottom surfaces of the outer sole elementsis set at about 1.3 or more in the rear foot part. A vertical compressive stiffness of the deformation elementdisposed on the lateral side is smaller than that of the deformation elementdisposed on the medial side.
