Patent number: 10709204Abstract: A shoe (34) of the present invention includes a sole (32) and an upper (33). The upper (33) is composed of a fabric having a knit structure, and contains fiber reinforcement portions (23, 24, and 25) in predetermined portions of the upper (33) integrally. The fiber reinforcement portions (23, 24, and 25) are formed of a float stitch with a plurality of float stitch yarns (19). The shoe of the present invention imparts a proper fit to a wearer's foot by forming the upper composed of the fabric having the knit structure that stretches properly. Also, in the case where the direction of foot force is suddenly changed while the sole contacts the ground, the shoe can hold the foot in desired predetermined positions by the fiber reinforcement portions situated in predetermined positions of the upper integrally. Thus, the present invention provides a shoe having proper holding properties while maintaining fitting properties.Type: GrantFiled: August 7, 2014Date of Patent: July 14, 2020Assignee: MIZUNO CORPORATIONInventors: Kazunori Iuchi, Tetsuo Yamamoto, Terumasa Kita
