Abstract: 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.

Abstract: 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.

Abstract: Ventilated footwear formed of an upper of impermeable material having its lower margin spaced from the upper surface of the sole, whether inner or tread sole, and socklining, to provide a space for ventilation, and the upper is secured to the sole by means including a rim of permeable material.

Abstract: Improvements in the safety and comfort of footwear having the appearance of having very thick soles and improvements in the method of their manufacture.
