Abstract: A sole structure includes a sole component, which has an inner surface and an outer surface opposite the inner surface. The sole component has a length and a thickness. The sole component includes a sole material, and the sole material has a density. At least one of the thickness or the density varies along the length of the sole component. The sole component defines a plurality of holes extending from at least one of the inner surface and the outer surface and arranged to form an auxetic structure. The auxetic structure is configured such that, when the sole component is tensioned in a first direction, the sole component expands in both the first direction and in a second direction orthogonal to the first direction. A property of the auxetic structure varies as a function of the density or the thickness of the sole component.

Abstract: An article of footwear includes a sole structure that has a front midsole component and a rear midsole component. A connecting member connects the front midsole component to the rear midsole component. The connecting member defines a groove at a lower side of the sole structure between the front midsole component and the rear midsole component. The front midsole component and the rear midsole component are pivotable relative to one another at the groove between a use position and an access position. Confronting surfaces of the connecting member at the groove are closer to one another in the access position than in the use position so that the groove is relatively open in the use position, and the groove is relatively closed in the access position.

Abstract: Sole structures, fluid transfer systems, foot support systems, articles of footwear, and/or other foot-receiving devices include one or more pumps (e.g., foot activated pumps) that facilitate movement of fluid within the sole structure/article of footwear, e.g., to change and/or control pressure (e.g., foot support pressure) in one or more fluid filled bladders included in the overall system.

Abstract: An article of footwear includes a textile component. The textile component of the upper includes a textile element and a tensile element. The tensile element defines a first segment disposed on a first side of the upper. The first segment of the tensile element is configured to attach the securement device to the textile element on the first side of the upper. The tensile element further includes a second segment that is disposed proximate the lower portion of the upper on the second side. The second segment is fixed relative to the lower portion of the upper on the second side. The tensile element further includes an intermediate segment that extends continuously from the first segment, across the heel region, to the second segment.

Abstract: A sole for article of footwear includes a midsole component having an inner surface and an outer surface opposite the inner surface. A plurality of blind holes each extends from the outer surface toward the inner surface. The plurality of blind holes are arranged in an auxetic configuration in the outer surface. Each hole in the plurality of holes extends towards the inner surface. The plurality of blind holes is arranged in a pattern that provides a tunable performance characteristic. The patterns of blind holes vary between different regions of the midsole component to provide different types of responses in the different regions.

Abstract: Foot support systems, e.g., for articles of footwear, include systems for changing the hardness or firmness of the foot support portion (e.g., of a sole structure) and/or systems for moving (e.g., selectively moving) fluid between various portions of the foot support system.

Abstract: A method of customizing the sole structure of an article of footwear includes providing a sole structure with a sole component having an inner surface and an opposite-facing outer surface. The sole component includes a plurality of inner recesses extending from the inner surface and a plurality of outer recesses extending from the outer surface, the plurality of inner recesses include a blind-hole inner recess, the plurality of outer recesses include a blind-hole outer recess, and the blind-hole inner recess is generally aligned with the blind hole outer recess along a vertical direction. The method further includes adjusting the flexibility of the sole component by selectively cutting or removing material from one or both of the blind-hole inner recess and the blind-hole outer recess.
