Ground-engaging structures for articles of footwear

Abstract:

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim at least partially defining an outer perimeter of the ground-engaging component and an open space at least at a forefoot support area, wherein the outer perimeter boundary rim defines an upper-facing surface and an opposite ground-facing surface; and (b) a forefoot edge support extending along and defining at least a portion of a first forefoot edge of the ground-engaging component. A bottom surface of the forefoot edge support (which may engage the ground) slants in an outward and downward direction from a location adjacent the open space toward the first forefoot edge. In some shoe pairs, the forefoot edge supports may be provided on a lateral forefoot side edge of one shoe, e.g., the right shoe, and on a medial forefoot side edge of the other shoe, e.g., the left shoe. The ground-engaging component(s) further may have "directional traction" features designed to support plant and rotation of the different feet when running a curve (e.g., on a curved or banked track).
