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.

Method of forming an article of footwear

A method is provided of making an upper for an article of footwear, the method including applying a liquid to select portions of a first substrate sheet of material, applying a powder to the first substrate sheet of material, applying suction to the first substrate sheet of material in order to remove the powder from portions of the first substrate sheet of material that are not coated with the liquid to form a selectively powdered sheet of material, applying additional liquid, additional powder, and additional suction to additional substrate sheets of material to form a stack of selectively powdered sheets of material, using compression and heat to join the stack of selectively powdered sheets of material into a partially cured structure, and removing uncured portions of sheet material from the partially cured structure leaving a cured structure. Different portions of the cured structure can have different properties.

Method of making footwear components

A last for forming an upper of an article of footwear includes a first portion including a lateral side and a medial side that opposes the lateral side, and a second portion connected with and extending upward and transversely outward in an angled manner away from the first portion such that a terminal end of the second portion is distanced from the first portion. An exterior surface of the last can include a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

Last for an article of footwear

A last for forming an upper of an article of footwear includes an exterior surface, where the exterior surface includes a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.
