Thermal and Environmental Resistance
- S7S Protection Class: In addition to all S3 features such as steel toe protection, closed heel, antistatic, energy absorption, fuel oil resistant sole (**FO**), and **puncture-resistant sole (P)**, the entire boot is **waterproof (WR)**.
- Heat Insulation (HI): The internal structure of the boot slows down heat transfer even in high-temperature environments, preventing feet from overheating.
- Cold Insulation (CI): The sole and inner lining create an excellent insulation layer against cold, maintaining the thermal comfort of the feet even in freezing temperatures.
- Heat Resistant Outsole (HRO): The outsole demonstrates resistance to contact heat of up to **300°C** for 60 seconds. It maximizes safety in hot environments such as welding, casting, and asphalt work.
- Fully Waterproof (WR): Completely prevents water from entering the boot even when working in rain, snow, puddles, and mud.
