ABSTRACT:
A sole component for footwear combining the desirable response characteristics of a fluid filled chamber and an elastomeric material. The chamber can be formed as a single bladder chamber in contact with an elastomeric midsole, or a single chamber formed by a sealing a void in elastomeric material. The interface between the chamber and elastomeric material is sloped and gradual so that the shape of the chamber and its placement in a midsole determine the combination of response characteristics in the sole component. The chamber has a relatively simple shape with one axis of symmetry with a rounded portion and a narrow portion.
