BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shoe soles such as athletic shoes to be worn for sports and mountain climbing, boots for fishing, and athletic shoes optimally used for footwear for construction.
It is intended to surely prevent sliding forward and backward and falling due to sliding.

[0002]

2. Description of the Related Art Conventionally, typical shapes of non-slip formed on the lower surface of the sole of sports shoes worn for sports, mountain climbing, etc. are, for example, straight lines, corrugations, lightning bolts, diamonds, and cylinders. There are shapes. For example, sliding is prevented by providing a large number in a direction substantially orthogonal to the axis of the shoe sole body.

[0003]

However, the above-mentioned conventional non-slip formed in, for example, a linear shape or a corrugated shape is provided in a direction substantially orthogonal to the axis of the shoe sole main body, and its shape is relatively monotonous, so that it is grounded. Since the direction of biting into the ground at this time is limited to one direction orthogonal to the axis of the shoe sole, when relatively light exercise such as normal walking is performed, the frictional force against the ground is sufficiently exerted to the front and Prevent backward sliding. However, it has been unsuitable for sufficiently preventing the forward and backward sliding or preventing the fall due to the sliding when performing intense exercise such as sports and mountain climbing.

Further, in the conventional non-slip formed in a lightning bolt shape, a rhombus shape, a cylindrical shape or the like, the whole shape as one anti-slip is formed by combining fine straight or curved element sides. Therefore, the bite area of each bare side portion with respect to the ground becomes small. Therefore, the anti-skid function is not fully utilized. Therefore, it has been insufficient to prevent the sliding against the intense exercise such as sports.

In addition, when the user, such as a sports person, vigorously moves during exercise and receives a force from all directions such as front-back direction and left-right direction, sliding is prevented,
In order to prevent falls, it is necessary to consider the shape of the non-slip.

Therefore, the present invention not only performs relatively light exercise such as walking, but also slides in the front-back direction and falls due to sliding when performing intense exercise with a sudden force such as when performing sports. The purpose is to reliably prevent.

SUMMARY OF THE INVENTION In view of the above problems, the present invention has a generally arcuate lordotic anti-skid projection that bulges toward the toe portion on the lower surface of a shoe sole body formed of an elastic material such as rubber. A means of providing a strip and a substantially arch-shaped kyphotic anti-skid convex bulging toward the heel portion so as to cross each other in a direction substantially orthogonal to the axis of the shoe sole body.

[0008]

[Operation] A generally arcuate lordotic anti-skid ridge that bulges toward the toe portion provided in a direction substantially orthogonal to the axis of the sole body made of an elastic material such as rubber slides backward by biting into the ground. To prevent it from falling or slipping forward to prevent it from falling. In addition, the substantially arch-shaped kyphosis anti-skid ridges that bulge toward the heel part bite into the ground to prevent forward sliding, and when sliding, they are prevented from falling backward to the back.
