Abstract: Fluid systems, foot support systems (including sole structures), and/or articles of footwear include: (a) a foot support bladder; (b) a fluid reservoir; (c) a pump (e.g., a foot-activated pump) including an inlet and an outlet, the outlet supplying fluid to one of the fluid reservoir or the foot support bladder; (d) a first fluid line placing the foot support bladder or the fluid reservoir in fluid communication with the inlet of the pump; and (e) a second fluid line placing the foot support bladder in fluid communication with the fluid reservoir. Such fluid systems, foot support systems, and/or articles of footwear further may include one or more of: (i) a fluid line support member (e.g., for supporting one or both of the fluid lines); and/or (ii) a switch (e.g., for changing at least one of the fluid lines between an open configuration and a closed configuration).

Abstract: A sole structure for an article of footwear, the sole structure including a forefoot region and a heel region. The sole structure further includes a chassis plate, an outsole plate extending from the forefoot region to the heel region, the outsole plate including a recess disposed in a top surface, wherein the outsole plate is disposed below the chassis plate, and a cushioning element disposed within the recess.

Abstract: Footwear with integrally knit uppers having features for increasing containment around a wearer's foot, improving strength and durability, and incorporating touch feedback through increased coefficient of friction while removing weight due to traditional additional components. The knitted component may be radially knitted so that courses converge towards a common area, like the throat region of the upper. Additionally, a fusible yarn may be knit on at least the exterior-facing surface of a containment area of the knitted component to create additional lock-down along lines of containment. Further, tensile elements may be incorporated within the containment area to provide strength and lock-down along desired lines of containment. Additionally, the fusible yarn may be a grip yarn that creates areas with greater coefficients of friction.
