Abstract
The present invention is directed towards a two-layer outsole for use with a shoe. The outsole includes an outer layer, an inner layer, and a longitudinally extending axis. The outer layer forms the bottom of the outsole and has a plurality of first holes at spaced locations therethrough. The inner layer includes a base adjacent one side of the outer layer and a plurality of projections that extend from the base through the first holes in the outer layer, and terminate in a pointed free end. The projections protrude from the bottom of the outsole, and provide traction when the outsole interacts with the ground. The free end also forms a ridge. The ridge of each projection is substantially parallel to the longitudinal axis. In one embodiment, each projection has an outline with a tear-drop shape. It has been found that when projections with this configuration are used with non-metal cleats, excellent traction is obtained.
