Slip Resistance (mandatory ceramic-Nals test)
According to EN ISO 20345:2022, slip resistance is a mandatory requirement and is tested on a ceramic surface contaminated with sodium lauryl sulfate (NaLS) solution. This test, stricter than previous versions, simulates real slipping conditions and ensures that all certified safety footwear provides a minimum level of grip. The SRA, SRB, and SRC classifications have been removed in the new regulation, making the NaLS ceramic test the standard.

High-resistance TEXTILE anti-perforation midsole. Protects the foot from penetration by dangerous and sharp objects. At the same time, it ensures maximum flexibility and lightness for the foot.
COMPOSITE toe cap resistant to impacts up to 200 Joules, lightweight and metal-free, ideal for safely protecting the toes without adding weight to the footwear.
Unlike other materials, composite offers several advantages: thermal insulation (does not transmit heat), non-magnetic (not detected by metal detectors), and memory (in case of compression, it returns to its original shape, leaving toes free).

Scratch-Resistant Leather

Zero Abrasion technology uses leather finished with multiple layers of polyurethane to protect the upper from scratches, cuts, and wear. This solution ensures that the footwear maintains flawless performance and appearance even after months of intense use, providing advanced resistance against abrasive surfaces and mechanical environments—all while preserving foot comfort and breathability.

Heel Stability Support

The Stability Support device is engineered to maximize heel support when walking. Unlike standard systems, it focuses support on specific areas, reducing foot stress and enhancing weight distribution. This leads to more natural movements, benefiting the back and joints, notably for those standing for long hours, and also reduces internal wear of the safety footwear.
