Thermal and Environmental Insulation
- S7S Protection Class: This is the highest standard, meeting the most comprehensive safety requirements, including **full waterproofing (WR)** and a **puncture-resistant sole (P)**.
- Heat Resistant Outsole (HRO): The boot's outsole is resistant to contact temperatures of up to **300°C** for 60 seconds. Essential for those working with molten materials and hot surfaces.
- Cold Insulation (CI): Thanks to the boot sole's cold insulation, the thermal balance of the feet is maintained even in freezing cold conditions (down to -17°C).
- Heat Insulation (HI): The interior of the boot reduces heat transfer in high-temperature environments, preventing the feet from overheating.
- Fully Waterproof (WR): Water cannot penetrate the boot. Provides all-day dry working conditions on wet, muddy, and watery surfaces.
