Waterproof shoe structure

Abstract

A waterproof shoe structure comprises an upper and a sole. The upper comprises an outer layer, a lining layer, and a waterproof foot-like member. The waterproof foot-like is integrally formed of latex. The lining layer has a foot-like configuration and is mounted inside the waterproof foot-like member. The outer layer covers the waterproof foot-like member. The outer layer, the lining layer, and the waterproof foot-like member are securely engaged together. The sole is then securely engaged with the outer layer of the upper.

What is claimed is:  
     
         1 . A waterproof shoe structure comprising: 
 an upper comprising an outer layer, a lining layer, and a waterproof foot-like member, the waterproof foot-like being integrally formed of latex, the lining layer having a foot-like configuration and being mounted inside the waterproof foot-like member, the outer layer covering the waterproof foot-like member, the outer layer, the lining layer, and the waterproof foot-like member being securely engaged together; and    a sole securely engaged with the outer layer of the upper.    
     
     
         2 . The waterproof shoe structure as claimed in  claim 1 , wherein the outer layer, the lining layer, and the waterproof foot-like member are sewn together along a sewing line not lower than an angle area of the upper.  
     
     
         3 . The waterproof shoe structure as claimed in  claim 1 , wherein the water foot-like member includes a bottom and a wall on the bottom.  
     
     
         4 . The waterproof shoe structure as claimed in  claim 3 , wherein the waterproof foot-like member is formed by immersing a foot-like mold into liquid latex and then heating the foot-like mold until formation of a foot-like member on an outer surface of the foot-like mold after thermosetting of the liquid latex.  
     
     
         5 . The waterproof shoe structure as claimed in  claim 3 , the waterproof foot-like member is formed by filling liquid latex into a foot-like interior space in a mold and then heating the mold until formation of a foot-like member on an inner periphery defining the foot-like interior space.  
     
     
         6 . A waterproof foot-like member for a waterproof shoe structure having an outer layer and a lining layer, the waterproof foot-like member being integrally formed of latex and attached between an outer layer and a lining layer of the waterproof shoe structure.  
     
     
         7 . The waterproof shoe structure as claimed in  claim 6 , wherein the waterproof foot-like member is formed by immersing a foot-like mold into liquid latex and then heating the foot-like mold until formation of a foot-like member on an outer surface of the foot-like mold after thermosetting of the liquid latex.  
     
     
         8 . The waterproof shoe structure as claimed in  claim 6 , the waterproof foot-like member is formed by filling liquid latex into a foot-like interior space in a mold and then heating the mold until formation of a foot-like member on an inner periphery defining the foot-like interior space.
