Safety Shoes S1

For dry indoor work environments: production, assembly, warehouse and workshops with a flat floor. In addition to the protective toe cap, S1 has an anti-static construction, a closed heel area and an energy-absorbing heel, but no penetration-resistant sole and no water-repellent upper.

It means the shoe discharges static build-up to the floor in a controlled way, so no spark occurs. Note: anti-static is not the same as ESD. Stricter limits apply for ESD-sensitive workplaces in electronics, and you need a shoe certified as an ESD shoe there.

S1PS means the shoe has all the properties of S1 plus a non-metallic anti-perforation sole. According to EN ISO 20345, this is tested with a 3 mm thick nail. The S1PL variant is tested with a thicker 4.5 mm nail, while S1P stands for a steel midsole. All three protect against stepping on sharp objects.

Only if the manufacturer has had that insole tested together with the shoe. A safety shoe is certified with the original insole; a different insole can change the space in the toe, the shock absorption and, for ESD models, the conductivity. If you need orthotic insoles, choose a solution that is approved for your model.
