The present invention relates to a method for the production of plastic footwear (10; 100) of the “full plastic” type by means of moulding using a polyurethane mixture (M; P). The method comprises the steps of: —providing a mould (20) having a mould cavity (22) defined by at least two impressions (28, 30) and designed to receive a shoe last (24) so as to define, when the mould (20) is closed, an interspace (26) having the shape and dimensions of the plastic footwear (10; 100) to be produced; —spraying a polyurethane mixture (M, P) onto said at least two impressions (28, 30) of the mould cavity (22); —inserting the shoe last (24) inside said mould cavity (22); —closing the mould cavity (22) so that the sprayed polyurethane mixture (M, P) occupies said interspace (26); —opening the mould (20), once at least the demoulding time (td) for the sprayed polyurethane mixture (M, P) has lapsed, such that the sprayed polyurethane mixture (M, P) has solidified inside the interspace (26) forming said plastic footwear (10, 100); —extracting the shoe last (24) from the mould cavity (22); —removing the plastic footwear (10, 100) from the shoe last (24).

Polyurethane injected boot assembly and associated manufacturing method

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.
