Abstract: Sole structures and articles of footwear include: (a) a foot support bladder chamber; (b) a fluid reservoir chamber; (c) a fluid line extending between the foot support bladder chamber and the fluid reservoir chamber and placing the foot support bladder chamber in fluid communication with the fluid reservoir chamber, wherein the fluid line extends outward from a heel area or a midfoot area of the foot support bladder chamber and/or the fluid reservoir chamber; and (d) a closure element for changing the fluid line between an open configuration and a closed configuration. The closure element may comprise a switch that is pivotally engaged with the footwear upper or sole structure. The fluid line may extend through a flap that projects outward from the heel or midfoot area of the foot support bladder chamber and/or the fluid reservoir chamber.

Abstract: Bladder systems include a fluid line formed between layers of thermoplastic elastomer. The fluid line may include: (i) a first fluid line region extending in a direction away from a main interior bladder chamber, (ii) a second fluid line region extending from the first fluid line region and in the direction away from the main interior bladder chamber, and (iii) a third fluid line region extending from the second fluid line region. The first and third fluid line regions have a larger transverse cross sectional area than that of the second fluid line region. The fluid line may connect a foot support bladder portion and a fluid reservoir portion in a sole structure/article of footwear. Also, the fluid line may be formed within a flap that extends outward from the main interior bladder chamber (e.g., one of the foot support bladder portion or the fluid reservoir portion).

Abstract: An adjustable modular shoe system includes interchangeable structural sole portions and an expandable expanding portion for enabling incremental resizing across both width and length vectors. Rigid sole portions in an array of sizes feature attachment points for securing locking mechanisms that couple to opposing plates arrayed along the bottom of an inherently stretchable expanding portion. Selectively positioning customized locking mechanisms having adjustable fixtures influences expansion forces applied to the coupled upper plates. This allows actively and continuously modulating expanding portion fit even after securing a given sole size. Different locking mechanism number, location, and bridging configurations transmit vectors parsed across zones needing more growth allowance compared to areas better retaining proportional shape. Incrementally tuning shoe sizing avoids one-size-fits-all industry increments dictated independent of anatomy.

Abstract: A sole structure for an article of footwear includes a first conical traction element disposed in a forefoot region of the sole structure. The sole structure also includes a first elongate traction element, a second elongate traction element, and a third elongate traction element arranged in a radial pattern around the first conical traction element within the forefoot region.
