Benefits of technology

[0018]As understood from the description given above, each of the aforementioned documents is not intended to improve frictional force on the assumption that a shoe is used on a dry road surface. However, there is some type of a shoe such as a shoe for marathon to be used mainly on a dry road surface in many cases. Increasing frictional force produced in a direction of running between an outsole and a road surface, etc. will facilitate the running of a runner. Further, performance may be improved during a play.
[0041]In terms of a relationship with a movement locus taken by a center of gravity, if the aforementioned angle exceeds 35°, the function of the longitudinally-long ridges will be reduced during running or walking.

Problems solved by technology

However, the aforementioned prior-art technique does not disclose anything about an instance where the width of a ridge is greater than the depth of a groove.

Abstract

An outsole of a shoe includes: a plurality of ridges having a tread surface to be in contact with a road surface; and at least one longitudinal groove defined between the plurality of ridges. At least in a partial area of each of a forefoot portion and a rear foot portion on a medial side of a foot, the plurality of ridges and the longitudinal groove extend in a longitudinal direction or a diagonal longitudinal direction and are set so that an angle of the ridges and that of the longitudinal groove with respect to a long axis of the outsole are in a range of 0° to 35°. A ratio of a length of the tread surface of the ridges with respect to a width of the tread surface is set to be 1.8 to 200. The width of the tread surface of the ridges is set to be greater than a width of the longitudinal groove by a factor of 2 to 100.

Description

TECHNICAL FIELD[0001]The present invention relates to a technique relating to an outsole capable of contributing to improvement of frictional force produced between an outsole of a shoe and a road surface or a floor surface.BACKGROUND ART[0002]A surface of an outsole is generally designed in consideration of an antislip function on a road surface or a floor surface wet with water or oil. Specifically, many protrusions or ridges are formed at the surface of the outsole.CITATION LISTPatent Literature[0003]First patent document: JP 08-280406A (front page)[0004]Second patent document: JP 2001-17203A (front page)[0005]Third patent document: WO 07 / 043651A (front page)[0006]Fourth patent document: JP 10-510744W (front page)[0007]Fifth patent document: JP 2011-255030A (front page)[0008]Sixth patent document: JP 49-76822Y (front page)DISCLOSURE OF INVENTION[0009]Each of the aforementioned patent documents describes little about antislip performance on a dry (dried off) road surface or floor ...
