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.

A waterproof shoe structure includes a sole, a vamp mounted on the sole, and a waterproof lining mounted on the vamp. The vamp is provided with a plurality of vent holes. The waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions. Each of the convex portions is higher than each of the concave portions. Each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp. The through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment.
