Non-slip sole structure

Abstract

A non-slip sole structure of anti-slip shoes used for stream trekking and fishing is made of a material with a large coefficient of friction such as unwoven fabric and having regular or irregular hollow grooves formed at predetermined positions of the sole to match with corresponding bumps, formed at the bottom of a shoe body. When the sole is combined with the bottom of the shoe body, the bumps at the bottom of the shoe body bottom are passed through the hollow grooves of the sole respectively and slightly protruded and exposed to achieve a more secured embedded positioning effect and provide an appropriate bending and extending deformation margin to the sole to avoid a stripping problem effectively. The bumps at the bottom of the shoe body are slightly protruded from the sole surface to improve an anti-slip grip effect and avoid wearing out the sole too quickly.

1 . A non-slip sole structure, comprising:
 a sole, made of a material with a large coefficient of friction; and   a shoe body, having a bottom securely combined to the sole, such that when a user steps or walks with the shoe body on a ground, the sole and the ground obtain a better friction to provide an anti-slip function;   characterized in that the sole comprises a plurality of hollow grooves formed at predetermined positions of the sole respectively, and a plurality of corresponding bumps formed at corresponding positions at the bottom of the shoe body respectively, such that when the sole and the shoe body are combined, the bumps at the bottom of the shoe body are passed through the hollow grooves of the sole respectively and exposed to the outside, and the sole and the shoe body are embedded and fixed with one another.   
     
     
         2 . The non-slip sole structure of  claim 1 , wherein each of the bumps formed at the bottom of the shoe body bottom has a height slightly greater than the thickness of the sole, so that when the sole is combined to the bottom of the shoe body, the bumps are passed through the hollow grooves of the sole respectively and slightly protruded from a surface of the sole. 
     
     
         3 . The non-slip sole structure of claim I, wherein the sole further includes a predetermined number of nails installed at a top surface of the sole, and an end of each nail is slightly protruded from the sole. 
     
     
         4 . The non-slip sole structure of  claim 1 , wherein the sole and the shoe body are combined and adhered with each other by a glue, and the glue is extended to contact interfaces between the bumps and the hollow grooves, in addition to a contact surface between the sole and the bottom of the shoe body. 
     
     
         5 . The non-slip sole structure of claim I. wherein the sole is integrated with the bottom of the shoe body during an injection molding process of the shoe body, so that the material for forming the shoe body is distributed to the preformed hollow grooves of the sole to form the bumps.
