Special Protection and Thermal Resistance
- Metatarsal Protection (M): A special layer that protects the bones on the top of the foot (metatarsals). This is vital for environments with falling heavy objects, such as foundries, metalworking, and construction.
- Heat Resistant Outsole (HRO): The outsole resists contact heat up to **300°C** for 60 seconds. Increases safety in areas with a risk of short-term contact with hot surfaces.
- Cold Insulation (CI): The sole provides insulation against cold, helping to protect feet from extreme cold.
- Heat Insulation (HI): The inner part of the boot slows down heat transfer at high temperatures, preventing feet from overheating.
