Upper Structure for a Sports Shoe

摘要

An upper structure for a sports shoe is provided that can not only enhance holdability as an upper but also improve wearer's touch on a foot. In the upper structure for the sports shoe, the upper is formed of a knitted fabric having thermally fusible yarn and another knitted fabric having no thermally fusible yarn. In the knitted fabric having the thermally fusible yarn, the thermally fusible yarn is disposed on an outer surface side of the upper, and on an inner surface side of the upper, a front yarn and a back yarn are arranged in a parallel relationship. The thermally fusible yarn is fusion-bonded and cured in the knitted fabric by heat treatment and the outer surface side of the upper 1 is thus hardened than the inner surface side of the upper.
