A method is provided for making footwear utilizing a spray-on material. The method can include spraying a spray-on fabric onto surfaces of a three dimensional last. The last can be produced using additive manufacturing techniques, such as 3D printing, based on data corresponding to dimensions and contours of a consumer's foot, and/or preselected aesthetic footwear designs. The spray-on fabric is sprayed onto the surfaces of the last and allowed to cure to form a flexible, non-woven fabric upper. The upper can be removed from the last and turned inside out. With the upper turned inside out, a sole can be joined to the fabric upper to form the footwear.

Method of manufacturing spray-on footwear

A footwear construction including a support cage that wraps an upper to provide an adaptive fit to accommodate a variety of foot shapes and to adapt to changes in foot shape during a gait cycle, while providing exceptional stability and support. The footwear can include an upper, a support cage and a sole assembly. The upper can be joined with the sole assembly and can include an exterior. The sole assembly can define a recess extending across a width of the sole assembly from a medial side to a lateral side. The support cage can be constructed from a semi-rigid but flexible polymeric material, disposed over the exterior of the upper and free floating relative to the exterior of the upper. The support cage can include a sole bridge that extends transverse to a longitudinal axis of the footwear, through the recess defined by the sole assembly.
