Safety shoes are designed to protect workers’ feet and are commonly used in workplaces where foot protection is required, such as construction sites and factory workshops. They are also known as labor protection shoes and are widely used in industries like industrial production, iron and steel metallurgy, machinery manufacturing, and automobile manufacturing.

There are many types of safety shoes. For example, there are those that protect toes, prevent punctures, are insulating, and resistant to acids and alkalis. Each type serves a specific function. The main function of anti – impact safety shoes is to prevent falling objects from injuring the feet, and their toe caps are made of impact – resistant materials.

When it comes to the selection of safety shoes, it should be based on the nature and degree of hazards in the working environment. After you’ve selected the style and color, there are several checks you need to perform. First, check whether the materials used for the upper of the safety shoes are genuine and meet the requirements. You need to distinguish between genuine leather and fake leather, and identify whether it is cowhide, pigskin, sheepskin or other types of leather. The lining material of safety shoes should be soft, with uniform thickness, and should not be easy to fall off or fade. Also, don’t forget to check the heels of safety shoes.

Regarding the usage guidelines, safety shoes should come with a product certificate and an instruction manual. Before use, you must read the manual according to the usage conditions and use them correctly. For special protective safety shoes, after use, you should check and keep them clean, and store them in a pollution – free and dry place. Sometimes, newly bought labor protection shoes may rub against the feet, but this doesn’t necessarily indicate a product quality issue.

**Grammar/Phrasing Issues & Suggestions:**
1. **”labor protection shoes”**: While technically correct, “safety shoes” or “protective footwear” is more common internationally. Use consistently.
2. **”anti – impact” / “impact – resistant”**: Hyphens should be connected: “anti-impact” and “impact-resistant”.
3. **”When it comes to the selection of safety shoes, it should be based on…”**: Awkward phrasing. Better: “The selection of safety shoes should be based on…”.
4. **”After you’ve selected the style and color, there are several checks you need to perform.”**: Shift from passive/formal to direct address (“you”). Better for consistency: “After selecting the style and color, several checks should be performed.” or “Once the style and color are selected, several checks should be performed.”
5. **”check whether the materials used for the upper of the safety shoes are genuine”**: Repetitive (“safety shoes”). Better: “check whether the upper materials are genuine”.
6. **”should not be easy to fall off or fade”**: Awkward. Better: “should not fall off or fade easily”.
7. **”don’t forget to check”**: Too informal (“don’t”). Better: “Also, remember to check…” or “It is also important to check…”.
8. **”read the manual according to the usage conditions”**: Slightly awkward. Better: “read the manual carefully, considering the specific usage conditions,”.
9. **”For special protective safety shoes, after use, you should check and keep them clean…”**: Awkward structure. Better: “After use, special protective safety shoes should be checked, kept clean,”.
10. **”pollution – free”**: Hyphen should be connected: “pollution-free”.
11. **”newly bought labor protection shoes”**: Inconsistent term (use “safety shoes”). Also “rub against the feet” is slightly unnatural; “rub or cause discomfort” or “may be uncomfortable initially” is smoother.
