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, wherein the outer perimeter boundary rim is shaped such that the outer perimeter of the ground-engaging component tapers or curves inward moving from a forefoot support area to an arch support area, and wherein a narrowest dimension from a lateral side edge to a medial side edge of the outer perimeter boundary rim (across the open space) is located in a heel support area of the ground-engaging component; and (b) a support structure extending into or at least partially across the open space. The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.
