US Patent 9491985 Outsole tread pattern

A footwear sole includes an upper surface and a lower surface. The lower surface includes a plurality of tread members formed thereon. The tread members include a plurality of projections or lugs of various sizes and shapes which are grouped together into specific patterns. The material from which the projections are formed increases the shoe sole's ability to resist slipping on floor surfaces which are covered with oil, water, soap, snow, ice, etc. The shape and pattern of the projections or lugs enable them to channel fluids and penetrate hard slick surfaces to increase the footwear outsole's ability to resist slipping.
