Abstract: A footwear assembly having an upper that comprises a neoprene sock with a foot portion integrally connected to a leg portion. The foot portion has heel, vamp and under-foot portions. The leg portion has front shin, side wall, and rear calf-side portions. The upper has a unitary, outer, injection molded layer molded directly onto the foot and shin portions of the neoprene sock, while the sidewall and rear calf-side portions remain substantially uncovered by the injection molded layer. The injection molded layer encases the foot portion of the neoprene sock. The injection molded layer on the shin portion defines a shin guard portion having a necked down area integrally connected to the injection molded layer at the vamp portion, wherein the shin guard extends upwardly from the necked-down portion in an outwardly diverging shape away from the vamp.

Abstract: Footwear assembly comprising a foot bed in an interior area defined by an upper and positioned atop a sole assembly, wherein the foot bed has a plurality of air holes through the forefoot and/or arch portions, and has air channels connected to the air holes. A compressible convex pump in the foot bed's heel portion faces the sole assembly and is movable between expanded and compressed positions. In the expanded position, the pump supports a portion of the heel portion apart from the sole assembly to define an air chamber coupled to the air channels. Movement of the pump member from the expanded position to the compressed position causes the air chamber to collapse and forces air from the air chamber through the air channels and upwardly through the air holes into the interior area of the upper, wherein the pump member is biased toward the expanded position.
