A footwear sole construction has a cavity. The footwear sole construction includes pods disposed on the medial and lateral sides of the heel region of the sole. The pods may be formed independent from the sole or integral with the sole. In addition, the pods may be disposed on the forefoot region of the sole, as well as, around the entire periphery. The placement of the cavities directly control the degree of shock absorption. The pods may be disposed such that at least one of the cavities may be disposed to have an open end on one of the medial and lateral sides of the sole and another open end on the lower surface of the sole. The cavities also may be formed directly in the sole material. In such case, a support piece can be disposed in the cavities or a reinforcement piece can be disposed on the bottom of the sole. The cavities also may be formed in a support element disposed in the sole.

Sole construction for footwear

The footwear sole construction has a sole element disposed in the heel region of the sole. The sole element includes a first pod disposed on the medial side of the sole and a second pod disposed on the lateral side of the sole. The first pod is connected to the second pod by a web. A lower side of the sole element defines a concavity such that a lower surface of the first and second pods are disposed for contacting a ground surface. The first and second pods each include cavities extending therethrough such that a first open end of a cavity is disposed on one of the medial and lateral sides of the pod and a second open end of that cavity is disposed on the lower surface of such pod. The placement of the cavities and the orientation of the pods allow for tailoring and control of shock absorption.
