Abstract
An article of footwear may include an outer member comprising a first ground engaging member extending substantially downward from the outer surface of an outer member. Ground engaging members may be auxetic structures that can increase their dimensions in a direction that is orthogonal to the direction of applied force or tension. The outer member may have a substantially uniform thickness. Ground engaging member shapes may include various polygonal features. The first ground engaging member may have a substantially three-pointed star-shaped pyramidal structure. The first ground engaging member may have three arm portions, a central region, a central tip, and an apex. The outer member may have an inner surface with apertures that correspond with the ground engaging members of the outer surface.
