A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

A method of forming an upper for an article of footwear includes depositing a fibrous material over a shoe last to form a fibrous material layer, where the fibrous material layer forms a portion of an upper of the article of footwear, flowing a polymer material within a mold so as to conform with a lower portion of the upper including the fibrous material layer, and drying the polymer material to form a sole structure for the article of footwear.
