Ground-engaging structures for articles of footwear

A ground-engaging component for an article of footwear, comprising:

• 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
• a matrix structure extending from the outer perimeter boundary rim and at least partially 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 the matrix structure defines:
• a first set of adjacent open cells extending completely through an entire thickness of the ground-engaging component and including at least three open cells that are substantially aligned in the forefoot support area along a first line extending in a forward medial-to-rear lateral direction, and wherein each of three open cells of the first set of adjacent open cells that are substantially aligned along the first line includes:
• (i) a sharp bottom ridge extending completely around that open cell, (ii) an upper opening having a curved perimeter with no distinct corners, and (iii) sloped sidewalls extending between the sharp bottom ridge and the upper opening, and
• a second set of adjacent open cells extending completely through the entire thickness of the ground-engaging component and including at least three open cells that are substantially aligned in the forefoot support area along a second line extending in a forward medial-to-rear lateral direction, wherein the second line is spaced forward from the first line.
