  • Patent number: 9204681
    Abstract: Boots having an appearance indicative of a particular style or construction can be constructed with portions of the boot that have an appearance and characteristics directed toward functionality other than appearance or style. Portions of a boot that are not generally visible when worn, for example, with pants or coveralls, include the shaft or chimney of the upper portion of the boot. The shaft of such boots can be constructed of materials that are generally waterproof or fluid-resistant, making the boot easier to clean and mitigating against dirt, mud, or other soiling factors from adhering to such portions of the boot. In combination with a generally visible portion of the boot, such as the vamp and toe box, having an indicative appearance, such boots allow for a wearer to both present footwear having a particular style and fluid-resistant or waterproof characteristics.

    Abstract: The present invention is a transparent thermoplastic polyurethane (TPU) comprising structural units of: a.) a diisocyanate; b.1) a polyester diol and b.2) a specific polyether diol and c.) a chain extender. The TPU has good combinations of light transmission and clarity, tensile strength, low temperature flexibility, and high moisture vapor transition rates compared to other commercial or known TPUs. A preferred example composition is a TPU that is based on MDI as the diisocyanate monomer, polycaprolactone as a polyester diol, an EO capped EO/PO polyether diol containing less than 20% EO, and butanediol as chain extender. These composition have good combinations of clarity, tensile strength, hydrolytic stability and processability compared to TPUs prepared using either polyester or polyether diols alone or the combination with a higher EO polyether diol.

    Abstract: A novel shoe construction provides a unique fit and feel to the shoe wearer's foot. The shoe construction is a variation in what is typically called vulcanized shoe construction. Wherein the conventional vulcanized shoe construction bands of flexible material are permanently adhered or vulcanized to the shoe sole and to a portion of the upper adjacent the shoe sole, in the shoe construction of the invention upper sections of the bands are let loose by being unattached to the shoe upper. In addition, a toe cap of the shoe and a heel counter of the shoe are secured to the shoe sole, but are unattached to the shoe upper. This construction results in a shoe that not only has a unique appearance, but also has a unique feel to the shoe wearer's foot with the upper surrounding the foot being free floating along the sides of the foot as well as across the toes and heel of the foot.

  • Publication number: 20080201981
    Abstract: A reinforcing elastic polymer, such as a urethane/rubber material, is selectively spray-applied over upper, midsole or outsole components of articles of footwear. Such a material sprayed over the toe area of baseball shoes, for example, that is subjected to increased wear during use, serves to improve the durability of that area. A cleated midsole constructed of a lightweight foamed material such as EVA, has an elastic polymer outsole layer selectively spray-applied over the outer surface of the cleated midsole to form a combination midsole/outsole that provides improved durability and traction, as well as superior shock absorption characteristics.

  • Patent number: 6978557
    Abstract: A method for manufacturing shoes is provided. The method includes preparing an upper and an outsole, applying an adhesive agent to the outer surface of an upper seal portion and the inner surface of an outsole seal portion, stitching together the outer surface of the upper seal portion and inner surface of the outsole seal portion, activating the adhesive agent by applying heat to the stitched seal portions, and molding the upper and the outsole by using a molding machine. Therefore, since the amount of the upper can be reduced and a separate insole is not necessary, the total weight of the shoes can also be reduced. The flexibility of shoes can also be enhanced.
