Shoes have been tested in accordance with the specifications of DIN EN 61340. They generally have a volume resistance of 7.5 x 10^5 to 3.5 x 10^7 ohms.
Safety class S3
Shoes with a protective toe cap made of aluminum, plastic or steel. They are slip-resistant, antistatic, waterproof and have energy absorption capacity in the heel area. They also have a puncture-resistant steel midsole, a profiled outsole and a closed heel area. A fuel-resistant sole is also possible.
Steel toe cap
Steel toe caps are somewhat heavier than other materials, but are very stable and resistant. As a rule, they can withstand a force of at least 200 joules.
Slip resistance SRC
The shoe is slip-resistant both on ceramic tiles with NaLS (sodium sulphate solution) and on steel floors with glycerine.
Penetration protection/midsole metal-free
The penetration protection protects the foot from nails and other sharp objects. Metal-free penetration protection made of textile fabric is lighter and more flexible and covers the entire surface of the foot. However, very sharp objects can penetrate it.
Exchangeable insole
The insole is not firmly integrated into the shoe, but only inserted loosely. It can therefore be easily replaced if necessary.
