  • Patent number: 8028440
    Abstract: Articles of footwear include a textile upper member with an exterior constructed from knitted textile material, the exterior including a region with stability ribs and a second unribbed region. The region(s) having stability ribs may be located, for example: along a lateral midfoot side of the upper member; along a forefoot portion of the upper member; and/or along a medial midfoot side of the upper member. Other articles of footwear include an upper member having exterior and interior textile elements joined together in a stitchless manner at the foot-receiving opening of the upper member. The exterior surface of this upper member also may include one or more regions with stability structures. The stitchless textile engagement techniques can provide a smooth, non-bulky, and breathable joint that does not require thick layers of textile material in contact with or adjacent the wearer's foot.

  • Patent number: 6670029
    Abstract: A method of manufacturing a multi-layer, composite footwear upper having a three-dimensional geometry includes the steps of forming a substantially planar composite sheet from two or more layers, heating the composite sheet, and compression molding the composite sheet into the three-dimensional geometry of the footwear upper. The composite sheet is formed by laminating a first layer of thermoplastic foam to a second layer of thermoplastic urethane (TPU), preferably in the form of a TPU film. A third layer of mesh fabric can be interposed between the first and second layers. The composite sheet is compressed after heating in a mold cavity to achieve the desired three-dimensional geometry. The composite sheet can be compression molded into separate sections which are assembled after molding to form the footwear upper. Alternatively, the composite sheet can be compression molded into a seamless, unitary footwear upper that requires minimal, if any, assembly for completion.

  • Patent number: 4019265
    Abstract: This invention provides a unitary blank which is rectangular-like in shape with the sides and the ends of the rectangle being modified so that when the one end and part of the sides are sewn together with an elastic thread in accordance with this invention it is readily formed into a shoe cover which fits snugly a large variety of sizes of shoes. The blank has, in effect, three parts which are the top section, the bottom section and the two side sections. The top section comprises two angularly flared portions each portion extending from a point near the center of the top and going toward its respective side section at a desired angle as is explained hereinafter. The bottom section comprises two rounded sections each extending toward the side section adjacent to it, and the two side sections are portions each of which is in effect a reversing curve joining the rounded bottom section with its related top section.
