Ground-engaging structures for articles of footwear

An article of footwear, comprising:

• an upper;
• and
• a sole structure engaged with the upper, the sole structure including a ground-engaging component that includes:
• 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 wherein a rearmost extent of the outer perimeter boundary rim is located within one of:
• an arch support area or a forward heel support area of the ground-engaging component;
• and
• a support structure extending from the outer perimeter boundary rim and at least partially across the open space;
• wherein the support structure includes 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 within the open space at least at the forefoot support area;
• wherein the matrix structure further defines a first set of open cells, wherein geographical centers of openings of at least three cells of the first set of open cells are substantially aligned along a line that extends from a rear lateral direction toward a forward medial direction of the ground-engaging component, and wherein the matrix structure further defines a second set of open cells located forward of the first set of open cells, wherein geographical centers of openings of at least three cells of the second set of open cells are substantially aligned along a line that extends from the rear lateral direction toward the forward medial direction of the ground-engaging component;
• wherein the matrix structure further defines a first curved set of cells aligned along a first curve extending in a forward-to-rear direction of the ground-engaging component wherein the first curve is oriented so that a concave surface faces the medial side of the ground-engaging component and a convex surface faces the lateral side of the ground-engaging component, wherein the first curved set of cells includes from 4-18 at least partially open cells
• wherein the outer perimeter boundary rim of the ground-engaging component forms an outer lateral edge and an outer medial edge of the sole structure in a forefoot support area of the sole structure, and
• wherein the sole structure further includes a midsole component between the ground-engaging component and a bottom of the upper, wherein the midsole component forms the outer lateral edge and the outer medial edge of the sole structure through at least some of an arch support area of the sole structure.
