Counter Stiffeners Patents (Class 36/68)
  • Patent number: 4783909
    Abstract: A shoe is provided with a reversible heel counter so the shoe can be selectively used as either a slipper or a regular shoe. An inclined slit is placed in each of the quarters, running from the upper edge toward the lower corner of the quarters adjacent the edge that will be joined to the other quarter. The slit is restitched with a zigzag stitch to form a butt joint which acts like a hinge. The quarters are then joined. A generally parabolic shaped heel counter is fastened over the joint, at the upper edge of the quarters, with the tip of the heel counter depending towards the bottom of the quarters where the insole attaches. The hinge line in each of the quarters adjacent the heel allow the heel counter to be selectively positioned down against an insole of a shoe to be used as a heel seat to form a slipper. When the heel counter is positioned upright in a heel counter position, a regular shoe is provided.

  • Patent number: 4766679
    Abstract: A midsole for athletic shoes, especially for medium and long distance track events, of soft elastic material, which in the heel area has, on its underside, a recess into which is inserted a stabilizing element of a material that is harder than that of the midsole is improved so that harmful supination positions are avoided. This is achieved by the fact that the stabilizing element (9) consists of a U-shaped part (10), covering the entire heel edge area, and a part which closes the U-shaped part at the middle part of the foot in a manner creating a window (13) into which an island of the full thickness of the midsole engages. The stabilizing element (9) also has a strip which extends along the lateral side of the midsole up to at least, approximately, the little toe area of a shoe provided with such a midsole.

  • Patent number: 4706316
    Abstract: A method for the production of footwear is disclosed which comprises providing and attaching a midsole member with integrated toe and heel counters. The process provides for efficient use of labor and machinery by reducing the number of steps required in footwear production and by reducing the number of machines required. The method comprises placing the midsole over a liner, drawing a pre-formed upper over the midsole and attaching a sole to the upper. Attachment of the components is preferably by a heat-activated glue. The midsole component is adaptable to a number of applications by modifying such aspects as the size and shape of the toe and heel counters, the size, shape and/or presence of side walls, the contour and thickness of the bottom, and the attachment of shanks or other stiffening or resiliency modifying members.

  • Patent number: 4638576
    Abstract: In an athletic shoe, an external counter and cushion assembly includes a substantially rigid external counter extending medially to approximately the front flex line, and a rearfoot cushion member is mounted within the rigid counter. This assembly mounts externally to the heel and counter region of a lasted upper. The floor of the cushion member also extends forwardly toward the front-flex region of the shoe and is preferably wedge-shaped to serve as a heel-lift layer. The cushion walls are generally coextensive with the counter walls, insulating the upper from the rigid counter in this region. The external counter construction includes a base flange which mounts atop the midsole periphery on a plane substantially below the bottom surface of the foot.

  • Patent number: 4608769
    Abstract: An improved construction of a shoe which permits the wearer to more readily step into the shoe without the use of his hands and which does not result in damage to the shoe. The shoe's counter incorporates a rigid shoe horn member generally conforming to the shape of the wearer's heel. The lateral edges of the foot receiving opening in the upper of the shoe is rolled and padded so that it does not become crushed as the wearer's foot is slipped into the shoe. The tongue member is reinforced with a stiffner which, too, precludes the tongue from wrinkling and/or rolling up as the foot is inserted into the shoe. Finally, an adjustable elasticized securing mechanism is adapted to bridge the metatarsal arch is included to allow the foot to spread the shoe during entry but which restores the shoe to a tight fit once the foot is inside.

  • Patent number: 4580359
    Abstract: An improved golf shoe construction of the so-called "soft" variety. This golf shoe includes a sole comprised of an outsole layer and a midsole layer between which a plurality of spike retaining sockets are located. Attached to the midsole is a wedge shaped heel piece. According to one aspect of this invention, a cross shaped stabilizer shank is affixed between the midsole and heel piece. This shank design provides improved lateral arch aid support and enhances the torsional stiffness of the shoe. According to another aspect of this invention, the outsole and midsole are stitched and bonded together thus providing redundant attachment means thereby preventing delamination.

  • Patent number: 4566197
    Abstract: A shoe of the moccasin type is made crush- and deformation-resistant toe by use of a premolded box toe stiffener for stiffening the toe region of the shoe upper. The stiffener is of flexible, resiliently stable character, characteristically remaining in or reverting to its original configuration, including an upstanding flange of curved configuration for lying against and providing securement to the corresponding interior surface of the upper. Principal and side tabs extend rearwardly from the bottom edge of the flange for securement to the sole part of the upper, or to an insole. Exterior foot-opposed surfaces of the stiffener are coated with heat-activated adhesive for adhesive securement to said shoe interior surfaces. The flange has a rear, foot-side inner surface devoid of adhesive, being exposed within the shoe. The method of making the shoe involves thermally forming the stiffener by molding from a blank of heat-formable material.
