How much do you know about the structure of safety shoes?
April 10,2023
The structure of safety shoes is simply composed of soles, uppers, uppers, and heels.
There will be certain differences in the structure of different safety shoes. For example, anti-smashing safety shoes must have steel toe caps on the head. In order to prevent the steel toe caps from grinding the feet, there are usually steel toe sheaths for isolation. The anti-puncture safety shoes place a steel plate on the sole to protect the feet.
But generally speaking, the structure of safety shoes can be divided into:
1. The first layer of sole
The first layer of sole is commonly known as the outsole. Usually, the sole of labor insurance shoes has a unique pattern and non-slip design, which is characterized by anti-skid, wear-resistant, and bending-resistant strength. If it is a high temperature resistant shoe, then the sole must be made of high temperature resistant material.
2. Second layer sole
Above the first layer of bottom is the second layer of bottom, also known as the midsole, which is used to reduce the pressure on the feet and is suitable for long-term wear and improves comfort. A dry midsole is designed on top of the second layer of bottom. If it is a puncture-resistant safety shoe, a steel midsole (steel plate) is placed between the midsole and the dry midsole.
3. Insole
Above the second layer of sole is the insole. Even for the small structure of the insole, different safety shoe manufacturers may design different solutions to achieve the functions of comfort, breathability, antibacterial, deodorization, and shock absorption.
4. Upper surface
The outer structure is the upper surface, and the price of safety shoes varies greatly when choosing different materials, such as cowhide, pigskin, and leather.
5. Heel
The heel part usually adopts soft foam or sponge roll mouth or has a comfortable pad to protect the Achilles tendon, mainly to prevent heel injuries.
The usual labor insurance shoes are lace-up, equipped with cotton shoelaces and quick shoe buckles. There are differences in shoe eyelets such as copper, aluminum, and iron. Some safety shoes may be equipped with humanized designs such as reflective strips that reflect at night.
