Abstract: An article can include a layer disposed on the article, where the layer includes a plurality of materials each having a different hardness than an adjacent material. The plurality of materials is arranged on the article such that a stiffness of the article is gradated along a length of the article from a first portion to a second portion of the article. A stiffness of the second portion is greater than a stiffness of the first portion and the layer has a continuous and even gradation that extends along the entire length of the article. The article comprises a fabric on which the layer is disposed.

Abstract: Methods and systems are disclosed for apparel assembly using three-dimensional printing directly onto fabric apparel materials. Disclosed is a method and system for direct three-dimensional printing and assembly of an article of apparel, including designing a three-dimensional pattern for printing, positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using the designed pattern, curing the printed material, and removing the article from the three-dimensional printing system.

Abstract: A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.

Abstract: Footwear includes modifiable responsiveness and/or energy return properties. Such footwear may include: (a) a base foot support component that defines a passageway extending from the forefoot region to the heel region; (b) a forefoot securing system in the forefoot region; (c) a heel securing system in the heel region; and (d) a band (including at least one elastic or stretchable portion or region) extending through the passageway and connected with the forefoot and heel securing systems. The band may include features and/or may be attached with components that form portions of the forefoot and/or heel securing systems. Application of different tensile forces to the band modifies and controls the responsiveness and/or energy return properties of the footwear. The tensile forces may be changed, for example, by moving the heel end of the band from a first securing position to a second securing position.

The plurality of materials is arranged on the article of apparel such that a stiffness of the article of apparel is gradated along a length of the article of apparel from a first portion to a second portion of the article of apparel. A stiffness of the second portion is greater than a stiffness of the first portion and the layer has a continuous and even gradation that extends along the entire length of the article of apparel. The plurality of materials can also be arranged such that each one of segments of a printed material is disposed between a respective pair of segments of a different printed material.

Abstract: Methods and systems are disclosed for apparel assembly using three-dimensional printing directly onto fabric apparel materials. Disclosed is a method and system for direct three-dimensional printing and assembly of an article of apparel, including designing a three-dimensional pattern for printing, positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using the designed pattern, curing the printed material, and removing the article from the three-dimensional printing system.

Abstract: Articles of footwear in accordance with some aspects of this technology include a foot support component and/or heel counter structure that includes openings, voids, and/or grooves around the heel area. These openings, voids, or grooves may make the heel counter structure more conformable, lightweight, and/or flexible. The openings, voids, or grooves may allow the heel or heel counter structure to conform better to the heel/foot of a user, providing and an “adaptive” response, adapting differently to different heels. The openings, voids, or grooves may be customized within the heel counter component based on the shape of the foot and/or heel of the user. Additionally or alternatively, these openings, voids, or grooves may make the heel construction better to conform to the wearer's heel and better to contain and move with the wearer's heel, e.g., during use and to improve flexion, comfort, and fit.

Abstract: Articles of footwear in accordance with some aspects of this technology include a simple construction that includes three main parts, with each made from a single material and fit together in a releasable manner. The invention enhances the recyclability and sustainable nature of the article of footwear and shoe. At least some more specific aspects of this technology relate to footwear structure that may include three main parts: (a) an outer cage, which may include a single piece having features of: (i) a footwear upper and (ii) a sole structure having one or more cleat outer shells; (b) an inner upper component; and (c) a chassis and heel counter component with a bottom surface thereof that includes one or more cleat inserts and supports that fit inside the one or more cleat outer shells.

Abstract: Footwear lasts have size adjustment capabilities. As some more specific examples, footwear lasts may be adjustable in the longitudinal direction and/or in the girth dimension. In this manner, fewer physical lasts may be needed for making a full size run of footwear products. Additionally or alternatively, aspects of this adjustable last technology may be used for making customized footwear products, for making small runs of footwear products, and/or for adjusting sizes of existing footwear products.

Abstract: A sole structure for a footwear article includes a system of support structures that are arranged in a subunit. In some examples, the subunit can be at least partially enclosed by an exoskeleton. In some instances, the system of support structures can comprise at least a portion of a cartridge that can connect to another component in the sole structure. The cartridge can, in some examples, operate to attenuate a force.

Abstract: The present disclosure provides for making annealed additive manufacturing powder, where the powder can be used to make structures using additive manufacturing processes. The additive manufacturing powder can be annealed to improve the flowability of the powder. Once annealed, the powder can be used in the additive manufacturing process and structures can be formed by affixing the powder particles to one another (e.g., by reflowing and re-solidifying a material present in the powder particles). The annealed additive manufacturing powder can be formed in a layer-by-layer additive process to produce articles such as a component of an article of sporting equipment, apparel or footwear, including a sole structure for footwear.
