Let's start with the sole
The sole is the foundation of every safety shoe. When choosing footwear according to the sole, always consider the work you will use the shoes for. There are 5 basic types according to the type of sole and midsole (the comfort layer that does not come into contact with the ground).
Polyurethane sole of uniform density.
High-density polyurethane sole with lower-density polyurethane padding.
High-density polyurethane sole with lower-density thermoplastic polyurethane padding.
Midsole made of low-density polyurethane, rubber sole.
Midsole made of low-density polyurethane, sole made of a nitrile and rubber mixture.
But do not forget a comfortable insole (the inside of the sole that comes in contact with the foot) and a durable upper (tongue, throat, quarter), which should be made of quality leather or another durable material.
Special professions require special protection
Your profession may present a specific danger to your feet. In this case, ordinary protection is not enough and you need specialized footwear. What cases are these?
If you work with heavy objects that can fall on your feet, you need protection for your so-called metatarsal bones in your instep. This protection is provided, for example, by the STEELER METATARSAL S3 HRO M SRA ankle shoe.
The upper of chainsaw-resistant footwear is made of a special fabric that tangles in the chainsaw chain during contact and causes it to stop. An example of such a model is the GRIZZLY 3SIC S3 WR HI CI SRC high ankle boot.
Not only does the STEELER FOUNDER S3 HRO SRA shoe resist temperatures of up to 300 °C, but in case of direct contact with a hot object, the special shoes can be quickly shaken off without untying them.
Static electricity protection
Apart from the worker, shoes designed for ESD environments (combined with other elements, such as floor surface treatment, ESD gloves and protective clothing) also protect the product itself (e.g. computer components). Examples include the TOPOLINO ESD S1P SRC sandal.
