1. Sole material

There are common rubber, vulcanized rubber, or polyvinyl chloride.

The function of the sole is mainly abrasion resistance, chemical resistance, heat insulation and oil resistance, but due to the different characteristics of various materials, the function is also different.

The steel plate is installed on the safety shoe's midsole to prevent the sole from being punctured by nails or hard objects.

In addition, soles made of certain materials can reduce the generation of static electricity or relieve the speed of electrostatic discharge. This controls the potential for static electricity to cause an explosion or fire.

2. Sole design

In addition to using a non-slip rubber sole, the design of the sole is also important for anti-slip functions.

3. Body material

Commonly there are leather, artificial leather, polyvinyl chloride and synthetic fibers. Each of these substances has advantages such as:

The leather body is more durable and more comfortable to wear, but its anti-corrosive liquid damage function is not good.

Artificial leather can be applied in the case of waterproof, corrosive chemicals or other contaminants, but if the surface is depleted, the function will be affected.

PVC is most suitable for use in wet conditions and is also easy to clean but can be decomposed by some chemicals.

Synthetic fiber shoes are easier to clean and resist chemical decomposition.

4. Body design

With reference to European standards, there are the following five styles.

A shoes;

B ankle boots;

C half knee boots;

D knee boots;

E leg boots.

5. Toe selection

The main function of the safety shoes is to protect the toes from being bruised or bruised. If employees are required to perform heavy work, such as construction workers or employees handling heavy goods, the materials used to manufacture safety shoes and steel caps must have corrosion resistance and impact resistance of 200 joules (J).
