Systems and methods are involved with but are not limited to: placing one or more leather portions in a mold, the mold including a cavity with a cavity shape; placing rubber material in the mold; and applying heat to the one or more leather portions and the rubber material while the one or more leather portions and the rubber material are in the mold and subsequently cooling the one or more leather portions and the rubber material thereby fusing one or more portions of the rubber material to the one or more leather portions and thereby conforming one or more portions of the rubber material to one or more portions of the cavity shape. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure.

An article of footwear is disclosed. The article of footwear includes an insole made of polyurethane with a thickness of at least 8 mm at its thickest point, the insole comprising an arch support designed to distribute the pressure of a foot; an outsole made of leather with an edge-to-edge rubber that is inlaid into a forepart of the outsole, and a midsole sandwiched between the insole and the outsole.

Disclosed is a method for producing a shoe sole. The shoe sole includes: a shoe sole fabric having the form of a sole; a protective cover having the form corresponding to the form of the shoe sole fabric and bonded to a lower surface of the shoe sole fabric with a plurality of pillar through holes vertically penetrating the protective cover; and a plurality of pillar pieces passing through the plurality of pillar through holes, and bonded to the lower surface of the shoe sole fabric and arranged in a form of protruding downward from the protective cover.

The present invention concerns a sole structure (10, 110, 910) comprising a tread (11, 111, 911), which comprises at least one portion of breathable material (11, 111, 911), and a midsole (12, 112, 212, 312, 912) coupled to said tread (11, 111, 911), said midsole having:at least one first channel (13, 113, 213, 313, 413, 513, 613, 713, 813) having at least one ventilation port (14) for the fluidic communication with the outside environment, at least one first through opening (15, 115, 215, 315) in fluidic communication with said at least one first channel (13, 113, 213, 313, 413, 513, 613, 713, 813), said sole structure (10, 110, 910) comprises a waterproof and breathable functional element (16, 216, 316) which seals said at least one first opening (15, 115, 215, 315) in a waterproof manner. A shoe (20) with said sole structure (10, 110, 910) is further object of the invention.

A substructure for footwear can be produced. An inner half-shell of an intermediate layer forms a foot support and a lower, adhesion-promoting layer is produced by heating a mass, pressing the heated mass with the adhesion-promoting layer to form the inner half-shell which is then cooled. A sole area is foamed without demolding the half-shell in a mold part, wherein a press die is introduced into the mold part for pressing the mass with the adhesion-promoting layer. After removal of the press die a mold cavity is placed sealingly on the mold part, so that a cavity in the form of the sole region remains between the lower, adhesion-promoting layer and the mold cavity, into which a plastic is injected or foamed.
