    Abstract: Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component; and (b) a matrix structure extending at least partially across the open space at least at the forefoot support area to define an open cellular construction with plural open cells in the open space at least at the forefoot support area. A plurality of these open cells of the open cellular construction have openings with curved perimeters and no distinct corners. Additional aspects of this invention relate to ground-engaging components that are very lightweight yet very stiff, particularly in the forefoot support area. Two or more sizes of the ground-engaging components may be provided with substantially constant forefoot stiffness (optionally substantially constant over a size run).

    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).
