Abstract
A shoe sole for supporting a wearer's foot. The sole has a main sole portion and at least one cushion associated with the main sole portion. The cushion includes first and second hollow tubular portions, preferably with resilient load-bearing first and second hollow walls that have a thickness, material, and shape providing sufficient strength for supporting and cushioning the sides of a corresponding foot region of a wearer's foot. The first wall is disposed on first side of a sole region of the sole, and the second wall is disposed on a second side of the sole region opposite from the first side. At least one of the first and second hollow walls extends along a third side of the sole region. A central portion of the cushion is disposed between and joined with the first and second tubular portions, and preferably has a thickness, material, and shape providing sufficient strength for supporting and cushioning a generally central part of the foot region between the first, second, and third sides.
