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 method for making a footwear upper assembly, including knitting a tube to form first and second sock portions integrally joined at an intermediate portion; defining a first sock void and a first opening in the first sock portion; turning the second sock portion inside out, folding relative to the intermediate portion, and moving the second sock portion into the first sock void; inserting a footbed through the first opening into a footbed void formed between first and second lower panels of respective first and second sock portions; and closing the first opening to trap the footbed between the first and second lower panels. Alternatively, the method includes placing the knit tube on a last, placing a footbed adjacent the first lower panel, turning the second sock portion right-side out and moving it around an exterior of the first sock portion, and trapping the footbed within the footbed void.

Provided are systems and methods for integrated control and safety systems (ICSSs) that employ intelligent personal protective equipment (PPE). In some embodiments, an industrial plant system includes an industrial safety system (ISS) for monitoring a safety status of an industrial plant and one or more intelligent PPE systems worn by personnel located in the industrial plant. Each of the intelligent PPE systems includes one or more intelligent PPE devices for sensing personal and environmental characteristics of a person wearing the intelligent PPE system, and transmits safety data corresponding to the personal and environmental characteristics sensed. The ISS collects the safety data, determines (based on the safety data) whether a safety incident has occurred and, in response to determining that a safety incident has occurred, executes a response to the safety incident.

A disposable waterproof bootsock is worn over foot and sock to protect from exposure to liquids, dirt and other contaminants in an environment that can penetrate footwear or reach above the ankle. The bootsock is secured about the wearer's calf and ankle using fasteners that accommodate a range of calf and ankle sizes and allow adjustment to the wearer's desired fit while maintaining the bootsock in position upright. One or more sealed compartments are provided to hold essential supplies.

A die-casting forming mold for vulcanized rubber boots, comprising: a combined shaft mold provided with an inner cavity corresponding to a shaft of a rubber boot; a last mold 21 provided with partition elements, comprising a body substantially corresponding to the shaft of the rubber boot in shape, and two or more partition elements disposed on the body, the last mold 21 being adapted to be mounted in the inner cavity of the shaft mold to form a die-casting forming cavity between the wall of the inner cavity of the shaft mold and the outer surface of the last mold 21, and the die-casting forming cavity being divided into two or more portions by the last mold 21 and the shaft mold, wherein the last mold 21 further comprises: a longitudinally extending rubber injection channel extending longitudinally downward from the upper surface of the last mold 21, and a transversely extending rubber injection channel extending transversely from the longitudinally extending rubber injection channel to a rubber outlet in the surface of the last mold 21; and a rubber injection plate 5 adapted to be mounted to the top of the shaft mold to guide the injection of an unvulcanized mixed rubber material, the rubber injection plate 5 being provided with: a rubber injection hole 11 adapted to be connected to an external injection head to inject the unvulcanized mixed rubber material, and a rubber injection channel for communicating the rubber injection hole 11 with the longitudinally extending rubber injection channel.

A heel protector (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section (101) and the foot engaging section (102) define a leg insertion aperture (104). The leg engaging section (101) defines at least one aperture (203) disposed in an ankle region (205) to permit a connection tube (1002) extending from an inflatable bladder (901) of a compression device (800) to pass therethrough. The heel protector (100) and compression device (800) work together as a rehabilitation system (1300).

A massaging boot assembly for massaging a foot includes a boot that may be worn on a foot. A massage unit is coupled to the boot and the massage unit selectively massages the foot when the boot is worn. The massage unit is selectively turned on and off. A heating unit is coupled to the boot such that the heating unit is in thermal communication with the boot. The heating unit is selectively turned on to selectively heat the foot thereby enhancing therapeutic relief of the foot.
