Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.

An automated system for painting a shoe sole portion of a shoe is provided. The automated painting system is adapted to use a variety of stations and components to automatically paint a side surface of the shoe sole portion while it is secured in a jig, transition the jig to an open position, and remove the painted shoe sole portion from the jig.

Laser siping forms sipes in an article. The laser operates in a scan laser configuration for some sipe patterns and the laser operates in a fixed laser concept for other siping patterns. The article on which the sipes are formed is secured by a part holder. Movement of the part holder may be computer controlled. Movement of the laser may also be computer controlled. A movement of a reflective surface of the laser may be computer controlled. Together, the movement of the part holder, the laser, and the reflective surface is coordinated to achieve the scan laser configuration and the fixed laser configuration when forming sipes.

A conditionally visible bite line may be demarcated on a shoe upper using at least one of a fluorescent or an Infrared (IR)-responsive material. Such a conditionally visible bite line may be observable only under particular conditions, such as when illuminated by an ultraviolet light source or an IR light source, as appropriate. A light may be projected to intersect the conditionally visible bite line under conditions rendering the conditionally visible bite line detectable. The intersection(s) of the projected light and the conditionally visible bite line may be used to create a virtual bite line for use in generating a tool path to process the surface of a shoe upper bounded by the conditionally visible bite line.

A manufacturing process involving a series of discrete operations can be modified by adding, removing, or reordering operations, without design changes to the equipment. The manufacturing process uses a frame comprising one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the pliable material on the frame from the interaction of the alignment elements on the frame and the manufacturing station. The operations at any particular manufacturing station can therefore be positioned independent of what operations, if any, have come before, or in what order.

A multi-colored effect for a sole structure for an article of footwear is disclosed. The sole structure comprises a sole member having a first color and an exterior layer having a second color that is different from the sole member. A plurality of slots are formed in the sole structure and the second color is visible on an outer surface of the sole structure through the plurality of slots.
