The outsole is formed from a viscoelastic body containing a rubber component. This viscoelastic body has a loss coefficient of 0.17 or more in dynamic viscoelasticity measurement under conditions of 23 ° C., frequency 10 Hz, static strain 10%, dynamic strain 7%, and dynamic viscoelasticity measurement under the same conditions. And the ratio of the tensile stress at 300% elongation to the tensile stress at 100% elongation is 4.4 or more. Such an outsole is excellent in wet grip properties and durability. |
