A method of manufacture of footwear and the footwear comprising the steps of providing a last with an upper thereon, providing a mold insert on the bottom of the last, providing a mold having a mold cavity for a tread sole, disposing the last and upper against the mold with the mold insert disposed within the mold cavity, forming a sole in the mold cavity having a depression therein in the shape of the mold insert, providing an insole with a first portion in the shape of the depression and a second portion substantially in the shape of the sole and securing the first portion of the insole in the depression. The tread sole and insole are formed of materials preferably having different physical properties. The tread sole can include one of tongues and grooves and the insole would then have the other of tongues and grooves, said tongues and grooves mating with each other. The step of providing an insole can include removing the mold insert from the mold cavity, disposing the last spaced from the tread sole and then forming the insole in the cavity formed by the removal of the weight relief and the spacing of the last from the tread sole.

Shoe with insole as part sole filler and method of making same

Boot sole

A method of manufacturing footwear and the footwear wherein the footwear is manufactured by providing a mold having a mold cavity, placing a sole member in the bottom of the mold cavity, placing a foamable material over the sole member within the mold cavity, providing a last having shoe upper means thereon, positioning the shoe upper means against the mold cavity to form an enclosed space therein formed by the shoe upper means and the sole member and foaming the foamable material within the enclosed space. The footwear comprises upper means and a sole member secured to the upper means, the sole member comprising a prevulcanized sole portion extending to and engaging the upper means to form a spew-proof cavity therebetween and a foamed material filling the cavity.

Method of footwear manufacture

Cold weather footwear includes at least three assemblies: an inner preformed sock comprised of inner and outer fabric layers and an intermediate open cell polyurethane foam layer enabling moisture transmission through the preformed sock; an insole assembly including a first layer formed of a moisture retaining or accumulating fabic, separable foam and intermediate sheet plastic non-moisture permeable plastic, and an underlying layer of closed cell thermally insulating foam for disposition between the inner sock and the sole of the boot; and a boot having a sole and a shell formed integrally with the boot, the shell being backcoated with a plastic material and coated with a water repellent. The footwear has adequate thermal insulation and moisture vapor transport characteristics, while affording good wind resistance and water repellency.

Cold weather footwear

Shoe sole

The disclosure relates to the manufacture of footwear with direct molded elastomeric soles wherein the last is built up in the center region to provide a sole which appears thick externally, yet is thin and relatively lightweight in its center region. The last includes grooves over the region of the stitches securing the upper to the welt to seal and waterproof the footwear in the region of the stitches by permitting the sole material, when molding takes place, to flow over the stitches.
