Aqua shoe having anti-slip structure

Abstract

A shoe with a superior wearing sensation is equipped with an anti-slip structure to forward comfort and safety in a watery place. The shoe includes an upper that covers an instep from above, an insole part that connects to the lower part of the upper and an outsole part which is integrated by adhesion with the insole part and the upper and which is supported by an outsole surface, wherein the outsole part is equipped with an anti-slip structure in which a plurality of suction parts are arranged while a suction part includes a cup that tightly contacts along the cup rim to the ground surface to provide, by being compressed, suction force and a protuberance that protrudes downward from the center of the cup.

         7 . The aqua shoe that is equipped with an anti-slip structure of  claim 4 , wherein the outsole part includes hexagonal outsole units, for which six connections that lie at an equal interval with a suction part as the center connect six suction parts to constitute an outsole unit. 
     
     
         8 . The aqua shoe that is equipped with an anti-slip structure of  claim 1 , wherein the upper and insole part aforementioned are integrated via the Bonis sewing method by which the upper and the insole part confront each other at their edge. 
     
     
         9 . The aqua shoe that is equipped with an anti-slip structure of  claim 1 , further comprising a web part that extends forward from the outsole part front and pushes against the stream in the water, wherein the web part is curve upward to forward water expulsion. 
     
     
         10 . The aqua shoe that is equipped with an anti-slip structure of  claim 1 , wherein the suction part further includes a protuberance that protrudes downward from the center of the cup. 
     
     
         11 . The aqua shoe that is equipped with an anti-slip structure of  claim 1 , wherein the outsole part includes one or more openings that vertically penetrate outside the suction part. 
     
     
         12 . The aqua shoe that is equipped with an anti-slip structure of  claim 1 , wherein the outsole part includes connections that link the tops of the suction part one another. 
     
     
         13 . The aqua shoe that is equipped with an anti-slip structure of a claim of  claim 5 , wherein the inlay is provided with one or more grooves, and sinks that shape as a ring and are depressed upward. 
     
     
         14 . The aqua shoe that is equipped with an anti-slip structure of a claim of  claim 5 , wherein the area in the inlay that corresponds to the heel, which initially contacts on the ground surface and to which the highest pressure is applied in walking, is provided with a friction area in which a plurality of protuberances. 
     
     
         15 . The aqua shoe that is equipped with an anti-slip structure of  claim 12 , wherein the outsole part includes hexagonal outsole units, for which six connections that lie at an equal interval with a suction part as the center connect six suction parts to constitute an outsole unit. 
     
     
         16 . The aqua shoe that is equipped with an anti-slip structure of  claim 9 , wherein the web part is provided with one or more reinforcement ribs to prevent the web part from deforming to a certain extent.
