And when the mine and the coal mine are operated, the falling objects are always generated, and the feet are easy to be injured by crashing. The traditional protective boots only pay attention to the injury protection of toes by crashing, however, the operation environment is often complicated and complicated, the accidents such as waste rock fall, iron material dump, mine car gliding, pickaxe dig foot, messy stone crowd foot and the like are inevitable, therefore, heels and ankles are also the key points of the protection of human joints, especially some objects that roll on the horizontal plane, also hurt heels and ankles very easily, therefore, need carry out the omnidirectional protection to human feet. The existing protective boots have relatively poor impact resistance, and when the impact resistance is met, the requirements of softness and comfort cannot be met. For example, the toe cap is an irregular member, the last itself is an irregular geometric body, and the manufacturing of the mold is troublesome and difficult. After the steel toe cap is added to the boot toe, the extension of the rubber surface is limited by the toe part, so that the toe part can not change along with the movement of the foot like the common rubber boot; the steel toe cap is too long, comfortable to wear and not easy to bend, and can cause damage to rubber materials at the edge of the toe cap, the size of the steel toe cap is short, and the steel toe cap cannot play a due protection role.
