摘要:
A vulc style and cupsole style footwear and a method for manufacturing the footwear are disclosed. The footwear includes a midsole that is directly attached to the upper. The midsole may be attached to the outsole by adhesive. In the method of manufacturing the footwear, the upper and an outsole are disposed a set distance apart. Polyurethane or other material for providing cushioning to the footwear is either injected between the upper and outsole or poured onto the outsole and the upper is traversed over the outsole so as to define the mold for defining the midsole. The polyurethane is directly attached to the upper and adhered to the outsole/cupsole.

The method of preparing a sole assembly intended to be attached to a shoe upper and/or midsole. A coat of primer is applied to a molded shoe sole and then conditioned. A film adhesive is pressed on to the primer coated surface of the sole under pressure. The primer may be dried before applying the adhesive film. The sole is conditioned at 40-90° C. for approximately 30-60 seconds and heat pressed at 40-90° C. at 40-70 psi for 5-30 seconds.
摘要:
An article of textile-soled footwear and method of making employ a simple fabrication process and apparatus that allows fabrication of the footwear outer shell via a single injection-molding step. The article of footwear has a textile layer at the ground-contacting surface of the outsole, the textile layer being moldably and integrally attached, in a common mold, to the molded outsole as it is being created during the injection process. Fasteners are set along the side of the sole plate of the injection mold to secure the textile layer across the sole plate and prevent it from being moved during injection of the moldable compound to form the outsole. The sole plate and the sidewalls of the injection mold are assembled in place for the injection process. The shoe upper is fitted onto the shoe last and set in place in the mold, the mold is closed, and the moldable compound is injected into the mold. Once injection is complete, the mold side walls are opened, the injected shoe is removed, and the excess textile layer is trimmed. In the preferred embodiment, the molded outsole layer is made of a thermoplastic resin and the ground-contacting textile layer is a combination of cotton, polyester, and Lycra®.

An article of footwear includes an air cushion sandwiched between an upper and an outsole. The air cushion confines an air chamber and has a bottom wall formed with a plurality of grooves that are respectively confined by groove-confining walls and that extend inwardly of the air chamber. The outsole includes a plurality of studs that respectively extend into the grooves and that are respectively bonded to the groove-confining walls.
摘要:
A footwear cushioning system including an insole and a midsole that define a chamber containing multiple, hollow, inverted, truncated cones. The insole includes a plate having a downwardly extending rib to define a recess. The midsole includes a midsole plate including an upwardly extending wall and multiple upwardly opening hollow, inverted frusto-conical cushion cells. The wall interfits within the rib, and the cushion cells abut against the insole plate. An outsole shell is direct-attached to the cushioning system with polyurethane. Preferably, the polyurethane pre-compresses the cushion cells and adds cushioning and energy return characteristics. To assemble the cushion system, an upper is stapled to the insole rib. The midsole is interfitted within the rib. The insole and midsole are heated to fuse the cushion cells to the insole. Polyurethane is poured into the outsole shell and the shell is direct attached to the upper/cushioning system.

摘要:
A shoe having a sole includes a molded, rubber outsole and a molded midsole disposed within the outsole. The midsole may be contoured or shaped to approximate the shape of the sole of a wearer's foot. An upper disposed around a last may have a base portion that will take the shape of the midsole. The upper is permanently secured to the outsole by a foxing that is cured by application of a vulcanization process to fuse to both the outsole and the upper.
