S1:P steel or plastic cap and closed heel section,
S1:P antistatic (depends on model), energy absorption capacity in heel area
S1P: steel or plastic cap and midsole against penetration, not watertight
S2:P like S1, but only for sectors with wet influences
S3:P like S2, additional midsole against penetration and more profiled outsole
ESD (Electro Static Discharge)
Protection shoes are described as ESD shoes if the peak is between 105 and 107 ohm. These shoes are recommended if it is necessary to reduce the electronic loading by deduction of the electrostatic loading.
Pollution, moisture and bending can significantly influence the electrical resistance.
The EN standards EN 344, 345, 346 and 347 regulate the basic requirements for safety-, protective- and working shoes for commercial use.
EN 344: Requirements and test procedures for for safety-, protective- and working shoes for
EN 344: commercial use
EN 345: Working shoes with steel cap (resilient up to 200J)
EN 345: (see S1 – S3 – categories)
EN 346: Working shoes with steel cap (resilient up to 100J)
EN 347: Working shoes without toe cap
