ABSTRACT:
A sole construction having a cushion insert that is installable in the sole at different orientations to vary the support/cushioning characteristics of the sole. The sole construction may include a midsole defining a receptacle configured to receive the cushion insert in a plurality of different orientations. The cushion insert and the receptacle may include a plurality of lobes that are interfitted when the cushion insert is installed in the receptacle. The size, shape and configuration of the lobes may be varied between different regions of the cushion insert so that different regions of the cushion insert provide different support/cushioning characteristics. The cushion insert and the receptacle may be generally disc-shaped so that the sole is adjusted simply by rotating the cushion insert with respect to the receptacle. The lobes may be configured so that rotation of the cushion insert adjusts the sole between supination, pronation, soft and firm settings.
