- JP2000-102402A is provided with a truncated cone-shaped protrusion that supports a spike pin.
- protrusions significantly increase the weight of the sole and hinder weight reduction of the sole.
- Another object of the present invention is to reduce the weight of the sole while maintaining the strength of the sole in the spike sole reinforced with reinforcing fibers.
