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 upper-facing surface and a ground-facing surface opposite the upper-facing surface, 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 from the outer perimeter boundary rim (e.g., the ground-facing surface and/or the upper-facing surface) and across the open space at least at the forefoot support area to define an open cellular construction with plural open cells across the open space at least at the forefoot support area, wherein a plurality (e.g., at least a majority) of the open cells have curved perimeters with no distinct corners.
