For this reason, the shoe sole of Patent Document 1 is unsuitable for sports shoes used for sports such as golf, tennis, soccer, rugby, etc., which can be performed even on rainy weather on a road with a lawn.
[0006]
Moreover, in the technique described in Patent Document 2, how to effectively use an anti-slip design having an anti-slip structure such as a groove shape, a block shape, a dot shape, and the like, the direction of the maximum friction direction, the direction of the shear direction, and the foot pressure are greatly affected. The anti-slip design itself is just securing the road surface grip by the frictional force caused by the contact between the anti-slip design and the road surface, as in the previous Patent Document 1. Absent. Therefore, the shoe sole of Patent Document 2 is also unsuitable for sports shoes used for sports such as golf, tennis, soccer, rugby, etc., which can be performed even on rainy weather on a lawn road.
[0007]
Further, in Patent Document 1, for example, foot pressure distribution data in various motion states such as walking, running, turning, jumping, and lateral movement is measured by a foot pressure distribution history measuring device, and foot pressure distribution data is obtained. The contact line / peeling line data is determined from the contact line / peeling line data, and the bending line data is determined from the contact line / peeling line data. Also in Patent Document 2, the essential friction coefficient distribution data is determined from the foot pressure distribution data and the load vector data measured by the foot pressure distribution history measuring device in each motion form, and further, the essential friction coefficient distribution data and the foot anatomy database are determined. The anti-slip area is determined based on the anti-slip area, and the anti-slip design is determined in the anti-slip area. It was such a thing.
