  • Publication number: 20130008059
    Abstract: The Present invention is directed to an anti-slip, wear-resistant sports shoe sole principally composed of a sole pad and a bottom cushion layer bonded to the bottom of said sole pad. The bottom cushion layer is composed of two parts, namely a soft under-cushion running inward from the front of the sole, and a hard under-cushion positioned at the heel and front of foot areas. The triangular area in the specially inclined underside design of the sports shoe sole, made of a low-density (soft) rubber material, includes a number of point-shaped protrusions clustered together to facilitate turns and twisting motions, while helping to prevent slipping, aid precision and increase comfort. Other than the triangular area, the whole of the underside of the heel and front of foot areas are made using a solid (hard) rubber material which is effective in terms of its anti-slip, wear-resistant properties.
