Compared with the protection steel plate used in the prior art, the weight of a single boot can be reduced by about 15-25g, fatigue feeling after one day of work can be reduced for miners, and adverse effects on the physical condition of the miners can be reduced after long-term use. In the conventional protective boots, a protective steel plate is usually only arranged at the toe part of the boot, a protective layer is not arranged at the instep part in consideration of wearing comfort, and even if the protective layer is arranged, a hard rubber strip or a glass fiber strip is generally used in consideration of cost, a whole piece of flexible protective material is not adopted, so that the protective boot cannot be well protected when the instep is subjected to single and punctiform heavy impact or penetration, the instep of a miner is injured, the protective boot in the embodiment is also provided with a foot-smashing prevention surface layer made of glass fiber cloth at the position corresponding to the instep of a human body, the glass fiber cloth has good tensile property, when the vamp at the instep part is subjected to heavy impact or spike penetration, the glass fiber cloth can play a role of buffering and preventing penetration, a good protective effect can be achieved on the instep of the miner, and the flexible glass fiber is arranged at the instep, so that wearing comfort can be ensured. The inner pad 31 in the insole 3 plays a role in increasing comfort of body feeling, the vibration reduction layer 32 plays a role in reducing vibration, and the puncture-preventing midsole 33 mainly plays a role in protecting soles from being punctured by sharp objects. The traditional protective boots generally adopt steel plate insoles for protection, and have good protective effect, but the boots can be particularly heavy in the wearing process, and the steel plate insoles can be very 'plate feet' in the walking process, so that the boots are very uncomfortable to wear. The puncture-proof midsole 33 in the embodiment is made of a kevlar material, which is a novel aramid fiber composite material, has low density, high strength, good toughness, high temperature resistance and easy processing and forming, has the strength which is 5 times that of steel with the same quality, but has the characteristic of being not in a tool, so that the kevlar material is widely applied to tanks, armored vehicles and bullet-proof jackets, even to nuclear-powered aircraft carriers and missile-driven vessels, and is gradually popularized and applied to the civil safety protection field due to the light and soft wearing experience of the kevlar material. The anti-puncture midsole 33 is made of the Kevlar material, so that the protective boot has the advantages of portability and comfort while playing a good role in preventing puncture.

The heavy protective boot for miners has the beneficial effects of portability, ventilation, softness, comfort, smash resistance and puncture resistance.
