Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.

This application is generally directed to articles including cage structures and related systems and methods. The cage structures have utility in footwear and apparel (e.g., articles of clothing, braces, accessories). In some cases, the article is a footwear article. In some cases, the article is an article of apparel. In some embodiments, the article includes a textile. In some embodiments, the article includes a cage structure (e.g., comprising a polymer) attached to a substrate (e.g., a textile). In some embodiments, the interface of attachment between the substrate and the cage structure is substantially free of an adhesive.

Methods for providing footwear configured to treat leg length discrepancy include manufacturing a plurality of footwear members. Each footwear member has a sole thickness, with sole thicknesses of the plurality of footwear members spanning a predetermined range of thicknesses. A corrective pair of footwear may be formed by selecting a left member having a first sole thickness and a right member having a second sole thickness, wherein the difference between the first and second sole thicknesses corresponds to an amount of leg length discrepancy to be corrected.

An apparatus for aligning materials in order to construct an article is provided. The apparatus may include an array of moveable pins and a solid plate having an array of holes, where the array of holes is aligned with the array of pins. Each pin may be extended and/or retracted by a programmable actuator array. When a pin is extended, at least a portion of the pin may extend through the hole with which it is aligned, such that at least a portion of the pin extends beyond the solid plate. A fraction of the total number of pins in the array of pins may be extended by the programmable actuator array. The particular pins that are to be extended may be based on a pattern for an article. A material that is to be used in constructing the article may be aligned using the extended pins.

A manufacturing frame comprises 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 flexible material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the flexible material on the frame from the interaction of the alignment elements on the frame and the manufacturing station.

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.

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.
