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.
