Footwear outsole including star shapes

A footwear outsole includes a base portion defining a tread attachment surface, and a plurality of tread members. The tread members are coupled to the tread attachment surface and protrude away from the tread attachment surface to define a tread member height. Each tread member includes a plurality of pointed arm members that extend away from a center portion of the tread member in a direction substantially parallel to a plane of the attachment surface. The arm members include a pointed tip that defines a maximum height of each tread member. The tread members include a primary surface facing away from the tread attachment surface. The primary surface includes a recessed portion that is reduced in height from the height of the plurality of edges. The tread members may be arranged in a pattern across the tread attachment surface.
