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.
