Abstract: An article of footwear and a method of manufacturing are provided. The article comprises an upper fixedly attached to a sole structure. The upper may comprise a wall wherein an inner layer is coupled to an outer layer, such that the inner layer and the outer layer define a closed pocket therebetween. A layer of scrap particulate matter is disposed in the closed pocket, and is at least partially visible through the outer layer, which is formed of a sufficiently transparent material. The sole structure is fabricated from a mixture of discrete pieces of scrap particulate matter and virgin polymer material, such that the discrete pieces of scrap particulate matter are at least partially visible on the outer surface of the sole structure. The sole structure is further substantially covered in a plurality of cavities and a plurality of protrusions, such that the outer sole surface has a crater-like texture.

Abstract: An article of footwear and a method of manufacturing the same are provided. The article comprises an upper fixedly attached to a sole structure. The upper may comprise a wall including an inner layer and an outer layer coupled to the inner layer, such that the inner layer and the outer layer define a closed pocket therebetween. A layer of scrap particulate matter is disposed in the closed pocket. The method comprises dividing scrap material into a plurality of discrete pieces of scrap particulate matter via a grinding or shredding process, inserting a layer of the discrete pieces of scrap particulate matter into the closed pocket formed between the inner layer and the outer layer of the wall of the upper. The outer layer may be formed of a sufficiently transparent material, such that the layer of scrap particulate matter is at least partially visible therethrough.
