Long – term use of unsuitable safety shoes can indeed cause various foot injuries. Safety shoes are designed to protect the feet, with types including those for toe protection, puncture prevention, insulation, and acid – alkali resistance. However, if not properly selected and used, they can become a source of harm.

One common issue is the sole and lining of safety shoes. If they are too hard, and you stand in these shoes for long periods, it may lead to over – use injuries of the feet. The hard materials can put excessive pressure on the feet, causing discomfort and potential long – term damage.

Another factor is the shoe size. When the shoe size is too small and too tight, it restricts the normal movement of the feet. This can lead to problems such as poor blood circulation, blisters, and even more serious foot deformities over time.

The shank of safety shoes is also crucial. It is installed between the outsole and the midsole to provide support and shaping. If the shank quality is poor, after wearing, the arch area may bulge or cave in. This makes the sole of the foot extremely uncomfortable, causes pain when walking, and can eventually lead to foot injuries.

To avoid these problems, when selecting safety shoes, it is important to base the choice on the nature and degree of hazards in the working environment. Safety shoes should come with a product certificate and an instruction manual. Before use, read the manual according to the usage conditions and use them correctly. For special protective safety shoes, check and keep them clean after use, and store them in a pollution – free and dry place. By taking these precautions, we can ensure that safety shoes serve their intended function of protecting the feet rather than causing harm.
