    摘要: Disclosed is a method for molding a foamed article, such as a midsole or outsole for footwear, in which a desired amount of thermoplastic polyurethane foam beads are placed in a compression mold in the shape of the article and the mold is brought to a peak temperature of from about 130° C. to about 180° C. over a period of from about 300 to about 1500 seconds, then cooled to from about 5° C. to about 80° C. over a period of from about 300 to about 1500 seconds within about 30 seconds after the peak temperature is reached. The foamed article made by the method has a density of from about 0.1 to about 0.45 g/cm3.

    摘要: An article of footwear includes an upper and a sole assembly secured to the upper. The sole assembly includes a lower ground engaging surface portion and an upper surface portion. The upper surface of the first portion is in contact with the upper. At least part of the lower ground engaging surface portion is a polymer material formed from a blend of polybutadiene polymer and a carboxylated butadiene-acrylonitrile or partially hydrogenated carboxylated butadiene acrylonitrile; wherein the polymer material has a density of 1.00-1.25 g/cm3 and a hardness of at least 55 Asker C.

    摘要: A method of making an article of footwear may include providing a last shaped to resemble a human foot. The method may also include forming at least one footwear component at least in part from a susceptor material that is thermally reactive to an electromagnetic field. The method may further include covering at least a portion of the last with two or more footwear components, wherein the two or more footwear components includes the at least one footwear component formed at least in part from a susceptor material. In addition, the method may include applying an electromagnetic field to the susceptor material, causing induction heating of the susceptor material and joining the two or more footwear components by melding the two or more components with the induction heating.
