Title:
SHOE SOLE, SHOE AND ANTISLIP MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/126192
Kind Code:
A1
Abstract:
The present invention provides a shoe sole that, not only immediately after bracing force starts to act but also after that, enables the bracing force to continue to act, and can exhibit excellent slip resistance even in walking on a walking surface under a bad condition such as walking on an ice surface. A shoe sole is designed to have a larger dynamic friction coefficient for an ice surface than a maximum static friction coefficient for the ice surface. It is desirable that the dynamic friction coefficient for the ice surface be 0.25 or more. These conditions can be achieved, for example, by a shoe sole wherein a plurality of antislip protrusions the lower end surfaces of which are each a ground contact plane are formed in a downward direction, a recessed portion recessed in a cone shape is formed in the lower end surface of each of the antislip protrusions, and steps are annularly formed on the inner peripheral surface of each of the recessed portions.
