Abstract

An article of footwear and a method of manufacturing the footwear are disclosed. The footwear has an upper and a sole structure. The upper is secured to sole structure and the upper is formed from three layers: a first layer, a second layer, and a third layer. The second layer is formed from a polymer material and molded to the first layer, but the second layer may alternately be molded to the third layer. The third layer is joined with at least one of the first layer and the second layer such that the second layer is positioned between the first layer and the third layer.
