However, the boots made of such PVC and rubber materials are generally heavy, which leads to inconvenience of increasing work fatigue.

In order to solve this problem, ethylene vinyl acetate (EVA) injection foaming boots, which are integrally manufactured by injecting and foaming ethylene vinyl acetate (EVA), have been used. However, the slip prevention function may be deteriorated due to the characteristics of the material.

In addition, in order to improve the ethylene-vinyl acetate (EVA) injection foaming boots, a non-slip rubber pad is cut and cut by a press cutting process in a body so as to have a slip prevention function.

However, the ethylene vinyl acetate (EVA) injection foam jacket may have a problem that the adhesion portion between the boot body and the bottom window is continuously exposed to water and foreign matter, thereby reducing the adhesive strength and detaching the sole.

In addition, the ethylene vinyl acetate (EVA) injection foam boots are prone to scratching and tearing of the boot body due to the surrounding obstacles in the working environment due to the characteristics of the ethylene vinyl acetate (EVA) foam material having poor durability, Water, foreign matter, etc. may be introduced into the inside of the boots due to the torn portion, resulting in injury of the wearer.

In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an EVA injection molded foam boot body 101 which is made of a rigid rubber having a slip- To minimize the time for which the adhesive 105 of the boots 101 and the bottom window 103 are exposed to water or foreign matter and prevent the bottom window 103 from being detached and adhered to the body 101, And an outer covering 102 made of a fabric having excellent durability at the lower end of the ankle.

SUMMARY OF THE INVENTION The present invention has been conceived in order to achieve the above object. In the ethylene vinyl acetate (EVA) Shaped bottom wall 103 having a space 104 formed in the inside of the boot made of rubber and a shell 102 made of a fabric having excellent scratch resistance is adhered to the lower end of the boots body ankle Is achieved by providing an ethylene vinyl acetate (EVA) foam boom (1).

As described in detail above, the ethylene vinyl acetate (EVA) injection foaming boot 1 of the present invention provides the following effects through the above-mentioned solution.

First, a cupsole-shaped bottom window 103 made of hard rubber functions to support the body 101 of a soft ethylene vinyl acetate (EVA) injection foam boots, and an ankle twisting phenomenon caused by an abnormal walking of the wearer Thereby preventing injuries.

Secondly, the cup-shaped bottom window 103 made of a hard rubber can prevent a slip phenomenon in a work place where water or foreign substances are present while performing a slip prevention function, thereby preventing a safety accident.

Thirdly, it is possible to minimize the time for which the joint part 105 with the boom body is exposed to the water and foreign substances on the floor, and to remove the floor window 103 due to the decrease of the adhesion force, Can be prevented.

Fourthly, the outer skin 102 formed of a fabric having excellent scratch resistance is adhered to the lower end of the ankle of the boot, so that water and foreign matter generated by breakage of boots and breakage of boots caused by scratching and tearing of the boot body by external obstacles So that the wearer can be prevented from being injured.
