Lightweight foam safety shoes

Abstract

The present invention provides safety shoes with a built-in toe cap, wherein a foam shoe in which the outsole and the upper are integrated by foaming a synthetic resin is formed, and a toe cap is inserted into a toe cap groove before the foam shoe is cooled by forming the toe cap groove at the outsole and the upper at the front inner part of the foam shoe. In the toe cap, a support border, comprising a metal material, making contact with the bottom, is formed at the lower end of a cover portion making contact with the upper, and a reinforcing piece crossing the bottom is formed at the support border by welding; or a ground plate, comprising an engineering plastic, which is in contact with the bottom, is formed at the lower end of a cover portion making contact with the upper.

What is claimed is: 
     
         1 . In the forming of a safety shoe incorporating a toe cap for covering a toe portion so as to safely protect the toe portion from external impact, a lightweight foam safety shoe characterized in that the safety shoe is formed as a foam shoe by foaming a synthetic resin material such that the foam shoe includes an outsole and an upper, which are integrated with each other, wherein toe cap insertion grooves, are formed in the outsole and the upper in the front portion of the foam shoe such that the toe cap is fitted into the toe cap insertion grooves, so as to be fixed therein before the foam shoe, which is formed by foaming, is cooled. 
     
     
         2 . The lightweight foam safety shoe according to  claim 1 , wherein the toe cap includes a support border formed of a metal material at the lower end of a cover portion, which comes into contact with the upper, so as to come into contact with the outsole, and a reinforcing piece welded to the support border by crossing the outsole. 
     
     
         3 . The lightweight foam safety shoe according to  claim 1 , wherein the toe cap includes a ground plate formed of an engineering plastic material at the lower end of the cover portion, which comes into contact with the upper, so as to be integrated with the lower end of the cover portion and comes into contact with the outsole.
