| 11. A cushioning device for location in a portion of a sole of footwear for aiding in the prevention of an over-supination
effect, the device comprising:
multiple vertically directed columns for location in a sole for footwear,
at least one of the columns being spaced apart from another column and being formed so that at least some of them have a relatively
different volumetric, elastometric or compression property relative to other columns;
at least one the columns being for location on a medial side and another of the columns being for location on a lateral side
of the footwear, the columns being adjacent each other and being spaced apart from each other, wherein the relatively different
volumetric, elastomeric or compression property aids in prevention of over-supination;
wherein the device is located between an upper support plate and a lower support plate, the support plates having more rigid
characteristics than the cushioning device;
an outer sole located substantially below the bottom plate and a mid-sole located substantially over the upper plate; and
an upwardly directed lip extending at least partly about an outer periphery of the cushioning device and wherein the upper
plate includes an upwardly extending skirt extending at least partly about a periphery of the upper plate, and wherein the
skirt of the cushioning device mates with an outer surface of a skirt of the upper plate and wherein the skirt of the upper
plates mates with an outer periphery of the mid-sole.
