Publication number: 20180317607Abstract: A covering member is provided in a portion of an upper of a shoe. The covering member includes: a fabric material comprised of a stretchable mesh fabric; and an overlay material made of an olefin-based thermoplastic elastomer and integrally provided on a surface of the fabric material. A direction intersecting with a stretch direction of the fabric material is defined as a width direction. The covering member has such strain rate dependence that a tensile load per unit width with respect to a strain amount of the covering member is higher and the covering member is less stretchable when a strain rate of the upper in the stretch direction of the fabric material is in a high strain rate region than when the strain rate of the upper is in a low strain rate region.Type: ApplicationFiled: December 2, 2016Publication date: November 8, 2018Inventors: Chie Yamamoto, Kazunori Iuchi, Naoki Yoshikawa, Yuri Naka
