Abstract

A conformable device (20) containing a conformable material (41) substantially comprising fluid matter which forms a resilient material substantially comprising solid matter after a working time is used in an article of footwear (44) in order to enhance conformance, comfort, fit, stability, cushioning and shock-absorption. The conformable material (41) is contained within a chamber (51) of suitable configurations. In addition, a foam material (66) of select shape generally conforming to a portion of the wearer'"'"'s anatomy can be used in cooperation with the conformable material (41), as well as a void (40) containing a gas. The invention permits accommodation to a wide range of anatomical features and characteristics found amongst a large percentage of the general public and application within numerous types of footwear (44).
