Abstract
An article of footwear includes a sole assembly defining a base support plane. The sole assembly also includes a cushioning assembly with a first end and a second end. The cushioning assembly includes a first cushioning member and a second cushioning member. The first cushioning member includes a first overlapping surface, and the second cushioning member includes a second overlapping surface. The first and second overlapping surfaces overlap each other over the base support plane and each slope at a positive acute angle relative to the base support plane. The first cushioning member is thicker than the second cushioning member adjacent the first end of the cushioning assembly, and the second cushioning member is thicker than the first cushioning member adjacent the second end of the cushioning assembly. The first cushioning member has a resistance to resilient deformation less than that of the second cushioning member.
