According to the estimated standard, the more important feature of industrial safety shoes is that the toe can withstand the impact of 20 kilograms of hard objects falling vertically from a height of 1 meter and absorb 200 joules of kinetic energy. Most contemporary safety shoes have also added other safety features and developed different categories of products. Including the rigid bottom plate design to prevent the soles of the feet from being pierced by nails and other sharp objects. Other relevant properties include slip resistance and grip. Other safety features of the sole include preset low anti-static properties, resistance to temperature changes, and resistance to specific fuels and chemicals.
Comfortable, hygienic and comfortable safety shoes can improve the work efficiency of workers and prevent chronic diseases of the feet or legs. The more important indicators of comfort performance include that the upper material must meet specific waterproof and breathable standards, the inner material should be easy to absorb sweat, and the smell is easy to dissipate after taking off the shoes. Other safety features include a well-fitting sole design, support for the foot and arch, softness and elasticity, foot pads and heel shock-proof design.

Durable industrial safety shoes must be made of cowhide or buffalo leather. The sole is usually directly cast into the upper, and the combination effect is quite perfect, which greatly reduces the phenomenon of peeling off, water seepage or sand and dust. The sole has the characteristics of durability, abrasion resistance and puncture resistance. Therefore, even in a difficult working environment, it can also play a role of safety protection in a fairly durable time. Fashion design is getting more and more attention from consumers, and more and more safety models are imitating the shape and color of sports shoes.
The toe guard steel head of safety shoes must have enough function to prevent heavy and sharp materials from impacting, and meet the national standards. Consumers should choose the type of toe-protecting safety shoes according to different workplaces. Among the five protection performance levels of An1, An2, An3, An4 and An5, which protect toe safety shoes, the An1 level is higher and the An5 level is lower. High-level toe protection safety shoes have high pressure and impact resistance at the front end of the product, and the protection of the toes is good, so the more the toes are susceptible to crushing or crushing, the more severe the injury It is necessary to choose high-level toe-protecting safety shoes, and for some toes that may be injured or crushed, and the degree of injury is unlikely to be serious, you can choose low-level toe-protecting safety shoes, because of the level High shoes are generally expensive, cumbersome to wear, and poor in comfort.
Therefore, the toe protection safety shoes should be selected appropriately according to the characteristics of the operation. Consumers can choose toe-protecting safety shoes with different prices, styles, and materials according to their needs. Generally, injection shoes are new and light, and the outsole is made of polyurethane material, which is wear-resistant and relatively expensive. Adhesive shoes are a traditional craft with a long production history, and the price varies according to their styles, materials, etc.; sewing The price of tire sole shoes is relatively cheap, and the price of tire soles varies depending on their style and materials.
In addition, injection shoes and adhesive shoes have poor air permeability, while sewn shoes have better air permeability and are more comfortable to wear. Consumers should first confirm whether the manufacturer of the product has an industrial product production license issued by the state (not required for imported goods) and a safety mark certification when purchasing. On this basis, check whether the product has the manufacturer’s name and address, production license number, safety mark certification number, production date, product standard number, whether it is accompanied by a product certificate and instruction manual, and pay special attention to whether the shoes are There are product name (or “toe protection” words), shoe size and protective performance level.
In addition, the distributor should be required to show the test report of the batch of products and check the validity period. Consumers should check the appearance quality when purchasing. You can check whether the upper surface is disabled, different colors, double stitches, skipped stitches, broken threads, uneven stitches; whether there is open glue or thread off the bottom of the upper; whether the sole has over-sulfur, under-sulfur, or sulphur spray ; Whether the inner toe cap is skewed, etc.
Usually the soles of safety shoes are made of PU materials or rubber materials. These materials change with time, the environment of use and the wearing habits of the wearer in physical and chemical characteristics, which make the safety shoes wear-resistant and adhesive fastness , Hardness, comfort and other functional aspects gradually weaken. Therefore, Xinnai safety shoes recommend to test the performance of safety shoes at intervals, and replace the unqualified ones.
