Abstract
A cushioning device for a footwear sole has multiple vertically directed columns. One column is located on a medial side and another is located on a lateral side, and are adjacent and spaced apart from each other. The medial column has the relatively larger volumetric property relative to the volumetric property of the lateral column. In another sense at least one of the columns has different elastomeric and/or compression properties relative to other columns. The device is located between an upper support plate and a lower support plate, and the support plates have more rigid characteristics than the cushioning device. Each column includes an upper larger area and a lower smaller area, and downwardly directed walls taper inwardly towards a lower location. The lower portion is where the bases of the columns are spaced apart.
