2. Description of Related Art
Workers working in vast variety of environments often require maximum protection for their feet from all kinds of accidents, i.e., pointed and piercing object from the ground, puncture from above and maybe even sideways. For example, miners working in a mine often require safety boots to protect their feet from the falling rocks. In order to do so, each of the safety boots is equipped with a steel plate mounted in the front portion thereof so that the miners' feet are protected.
Even with so many different safety or working boots available in the market, it seems that there is no design in the safety or working boots to protect the wearers' heel portions. Even though injury to the heel portion is not common in the highly hazardous working environment, workers still get hurt from time to time. As a result, it is necessary to provide a working boots with design in the heel portion to protect the wearer's heel portion from injury.

In a different embodiment, the slip-proof element includes multiple concaves. In still a different embodiment of the present invention, the sole 1 is made of a water-proof material.
With reference to
With the sole 10 of the present invention mounted inside the working boots, the user's heel portion is securely protected from injury caused by pointed object.
