  • Molded foam article, foamed sole, and shoe
    Patent number: 10113045
    Abstract: There is provided a molded foam article including a foam obtained by foaming a formation material wherein the formation material contains a resin component, an Asker C hardness of the foam is 10 degrees or more, and a ratio E40/E0 of the foam is 0.5 or more, the ratio E40/E0 being a ratio of an elastic coefficient E40 at a strain of 40% in relation to an elastic coefficient E0 at a strain of 0% of the foam. The molded foam article has appropriate softness with a small change in hardness under compressive deformation.
    Type: Grant
    Filed: May 31, 2012
    Date of Patent: October 30, 2018
    Assignee: ASICS CORPORATION
    Inventors: Junichiro Tateishi, Kenichi Harano, Keisuke Yamada, Mitsuo Nasako

  • Shoe sole with shock absorber structure
    Patent number: 6438870
    Abstract: A shock absorbing section (10) of a shoe sole (1) is provided with a shearing transformation element (11). This shearing transformation element (11, 11A) is supported at an upper position dislocated forward (F) with respect to a grounding surface (20) so that it performs a shearing transformation independently due to a load (W) applied from above.
