Abstract: The disclosure id directed to an article of footwear including an upper and the sole structure, to the sole structure, and to a method for manufacturing the sole structure and a method for manufacturing the article of footwear. The sole structure includes a fluid-filled chamber and an outsole that at least partially surrounds the chamber.

Abstract: A method of manufacturing a bladder element comprises forming at least one of a first, a second, and a third polymeric sheet to have a contoured surface profile. The first, the second, and the third polymeric sheets are stacked so that the second polymeric sheet is between the first polymeric sheet and the third polymeric sheet. The method comprises applying fluid pressure between the first polymeric sheet and second polymeric sheet, between the second polymeric sheet and the third polymeric sheet, or between both, forcing a first surface of the second polymeric sheet into contact with an inner surface of the first polymeric sheet, or a second surface of the second polymeric sheet into contact with an inner surface of the third polymeric sheet, or both. A bladder element is also disclosed.

Abstract: A sole structure for an article of footwear includes a bladder defining a peripheral chamber and a heel chamber fluidly isolated from the peripheral chamber. The peripheral chamber is configured as an elongated tube, and has a heel portion establishing a rear periphery of the bladder, a lateral arm portion extending from the heel portion and establishing a lateral periphery of the bladder, and a medial arm portion extending from the heel portion and establishing a medial periphery of the bladder. The bladder includes webbing connecting the heel chamber to the peripheral chamber, with the heel chamber disposed between the medial arm portion and the lateral arm portion and forward of the peripheral chamber in a heel region of the bladder. The bladder may include additional forefoot and midfoot chambers having specific shapes.

Abstract: A sole structure for an article of footwear comprises a midsole including a polymeric bladder element enclosing a fluid-filled interior cavity, a first outsole component secured to a bottom surface and to a side surface of the polymeric bladder element, and a second outsole component. The first outsole component includes a first base, and a wall integral with the first base. The second outsole component includes a second base secured to the first base, and a wall integral with the second base and secured to the outer surface of the wall of the first outsole component. A method of manufacturing the article of footwear includes thermoforming the bladder element and the first outsole component, and securing the second outsole component to the first outsole component.

Abstract: A footwear sole structure includes a midsole having a ground-facing surface with a forefoot region, a midfoot region, and a heel region. The midsole defines downwardly-extending protrusions at the ground-facing surface distributed over the midfoot region and the heel region, each of the downwardly-extending protrusions having a convex outer surface. A height of the midsole is greatest at the midfoot region. The sole structure may also include an outsole covering at least a portion of the ground-facing surface of the midsole, and a height of the sole structure may be greatest at the midfoot region.

Abstract: A sole structure for an article of footwear includes a chassis and a cushioning arrangement. The chassis includes a recess formed between a first surface and a second surface facing the first surface. The cushioning arrangement includes a first cushioning element protruding from the first surface and including a first plurality of lobes and a second cushioning element protruding from the second surface and including a second plurality of lobes contacting the first plurality of lobes. At least one of the first cushioning element and the second cushioning element may include a fluid-filled bladder. A first side of each cushioning element includes a substantially planar base and a second side of each cushioning element includes the lobes formed on an opposite side from the base. The base of each cushioning element is attached to a respective one of the surfaces of the recess.

Abstract: An article includes a base component defining a plurality of holes arranged in an auxetic configuration. The auxetic configuration is configured such that when the base component is compressed in a first direction, the base component contracts in both the first direction and in a second direction orthogonal to the first direction. A surface of the base component defines at least one of the plurality of holes is shaped as a one-sheeted hyperboloid.

Abstract: A sole structure for an article of footwear having an upper includes a heel region, a forefoot region, and a mid-foot region disposed between the heel region and the forefoot region. The sole structure also includes a fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a first segment extending between a medial side of the sole structure and a lateral side of the sole structure within the forefoot region, a second segment extending between the medial side of the sole structure and the lateral side of the sole structure within the forefoot region, and a web area disposed between and connecting the first segment and the second segment, the first barrier layer being attached to the second barrier layer within the web area.

The sole structure also includes a fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a first segment extending along a medial side of the sole structure within the heel region, a second segment extending from the medial side in the forefoot region to a lateral side in the heel region and along a lateral side of the sole structure within the heel region, and a web area disposed between and connecting the first segment and the second segment. The first barrier layer being attached to the second barrier layer within the web area.

Abstract: A bladder for an article of footwear extends from an anterior end to a posterior end and includes a first chamber disposed in an interior region of the bladder and a second chamber at least partially surrounding the first chamber. The first chamber includes a first interior void having a first pressure and the second chamber includes a second interior void having a second pressure. In some implementations, the second chamber includes a plurality of lobes arranged in series and each having a first end, a second end, and an intermediate portion disposed between the first end and the second end. Each lobe has a greater thickness at the intermediate portion than at the first end and the second end, such that each lobe tapers from the intermediate portion to the first end and the second end.
