A method of making a foamed article, for example a foamed component for an article or footwear, comprises forming a structure of interconnected, unfoamed, thermoplastic polymeric members spaced to define openings between the thermoplastic polymeric members. The structure may be made by printing a thermoplastic polymeric material with a three-dimensional printer. The thermoplastic polymeric members are heated to a first temperature to soften the thermoplastic polymeric members and the softened thermoplastic polymeric members are infused with at least one inert gas at a first pressure greater than atmospheric pressure. The first pressure is sufficient to cause the at least one inert gas to permeate into the softened thermoplastic polymeric members. After being infused with the inert gas, the pressure is reduced to at least partially foam the thermoplastic polymeric members.

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.

Designs and compositions of insoles for footwear are described herein. The insoles may be customized for a given foot. In some examples, the insole (100) includes a base comprising a variable thickness component (205), a directional stiffness component, a stability component, and a reinforcement component. The base may be a single composition that is manufactured using additive manufacturing techniques.

Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.

The present invention provides a method for designing of a piece of apparel in particular an upper of a shoe, comprising the steps of providing at least one first panel including a plurality of feature points in an essentially two-dimensional configuration, arranging the at least one first panel on a first reference body in a three-dimensional configuration representing the piece of apparel to be designed, generating a first mapping between the two-dimensional configuration of the at least one first panel and the three-dimensional configuration of the at least one first panel using the plurality of feature points and designing the piece of apparel using the first mapping.

An article of footwear has a tubular structure that may conform to various anatomical features of a foot. The tubular structure has a tunnel, and a tensile strand runs through the tunnel. Applying tension along the tensile strand may cause the tubular structure to conform more closely to one or more anatomical features. The geometry, or path, of the tubular structure on the article may be customized.

Described are methods for the manufacture of a shoe, an apparatus to perform such method, as well as a shoe manufactured by such method. According to certain examples, the method for the manufacture of a shoe includes providing a three-dimensionally pre-shaped first shoe component and processing the three-dimensionally pre-shaped first shoe component, wherein the processing includes an individually controllable succession of processing steps.

The present disclosure relates to systems and methods for generating orthotic device models using simulated patient anatomy. In one implementation, a method comprises receiving images of a body part of a patient; deriving physical measurements from the images; generating anatomy model data of the body part using the physical measurements; and generating orthotic model data based on the anatomy model data, the orthotic model data being representative of an orthotic device.

Systems and methods of determining spinal column and or leg length abnormalities includes taking digital photographs of multiple data points along the length of the person's spine and legs, and sending the photographs to a computer with a processor programmed with software that analyzes the photographs to determine leg length and spinal column length and spinal column curvature. The data regarding the leg length and curvature is sent to a medical professional for diagnosis and treatment of the patient.

An upper for an article of footwear, the upper including a base layer defining a least a portion of the upper and polymer threads stitched to the base layer. The polymer threads may include a core composed of a first material and a coating composed of a second material, where the melting point of the first material is higher than the melting point of the second material. The polymer threads may be bonded to the base layer by the coating of the polymer threads. The polymer threads may include one or more polymer thread sets stitched in pattern(s) on area(s) of an outer surface of the base layer to provide targeted characteristics to area(s) on the upper. In some embodiments, the polymer threads may be bonded to the base layer with heat and/or pressure.
