What components and characteristics of a safety shoe can provide adequate protection against mechanical and thermal risks?
Anti-Perforation Midsole
The anti-perforation soles are made from stainless steel or textile components. Again, the requirements of the standard are the same regardless of the material used. According to the standard EN 20345, the anti-perforation soles must resist the penetration of a nail of 4.5 mm in diameter under a pressure of 1,100 Newton.
The stainless-steel anti-perforation soles are placed between the insole and the sole. The non-metallic anti-perforation soles replace the insole.
As stainless-steel anti-perforation soles of the safety shoes (รองเท้า safety which is the term in Thai) are manufactured in standard sizes and not for a specific model, they are not precisely the same size as the sole and therefore do not protect the entire surface of the foot. On the contrary, as the non-metallic anti-perforation soles replace the insoles, 100% of the surface of the foot is protected.
The other advantages of non-metallic anti-perforation soles are that they are lighter and more flexible than stainless steel soles and conduct less heat and cold. The fact that the anti-puncture soles are more flexible promotes better contact of the foot with the ground, thus allowing a positive impact on the grip to a certain extent.
The advantage of stainless-steel anti-perforation soles is that they resist even the thinnest nails. Anti-perforation soles are recommended in specific construction trades, for example, where the risk of small sharp objects strewn on the ground is relatively high.
Covered Toe
Although the cut shown above does not have a covered toe, it can play a vital role in designing safety footwear for specific applications.
The essential role of the covered end is to protect the rod at the level of the end piece from mechanical stresses. This considerably reduces the natural wear and tear of the shoe like the sport safety shoes for woman (รองเท้า safety ทรง สปอร์ต ผู้หญิง which is the term in Thai) and thus prolongs its lifespan.
