Abstract
Methods for manufacturing at least a portion of an upper for an article of footwear that include thermo-forming a pattern on the upper. The methods may include disposing a skin for forming an upper over and inflatable bladder and disposing a mold insert between the skin and a surface of a mold cavity. The mold insert may include a mold pattern including surface features formed in the mold insert. The inflatable bladder may be inflated such that the skin is pressed against the mold insert within a heated mold cavity to form a pattern on an exterior surface of the skin and cause the skin to take on the shape of at least a portion of an upper. In some embodiments, the surface features may be disposed in a gradient pattern configured to provide varying degrees of one or more characteristics to different areas of an upper.
