Patent ID: 8544190

Claim:
A shock absorbing device for a shoe sole in a rear foot part comprising: a support element that supports at least whole of a rear foot part of a foot, the support element having a function of absorbing a shock of landing; deformation elements disposed below the support element in the rear foot part, the deformation elements deforming to be compressed vertically at landing; and outer sole elements contacting a ground at landing, each outer sole element being joined to a bottom surface of the respective deformation element, wherein both the deformation elements and the outer sole elements are substantially separated at least in a medial-lateral direction in the rear foot part to be arranged at least three regions of the rear foot part, a vertical compressive stiffness of the deformation element disposed on a lateral side of the rear foot part is smaller than that of the deformation element disposed on a medial side of the rear foot part.
