Cofra Thermic S5S Winter Safety Boot
Cofra Thermic D.Green is a metal-free polyurethane safety boot designed for work in cold conditions. Its S5S M CR AN CI HRO LG FO SR classification according to EN ISO 20345:2022 combines a 200 J fibreglass toe cap, a textile penetration-resistant midsole and additional metatarsal, ankle and upper protection.
According to the manufacturer, the COLD DEFENDER PU construction remains resistant at temperatures down to -25 °C. The cold-insulating, fleece-lined footbed and low-temperature-resistant nitrile rubber outsole support comfort in winter conditions. The boot is completely metal-free and therefore contains no metal components that could form a thermal bridge.

Safety markings explained
- EN ISO 20345:2022: Safety footwear standard requiring a toe cap tested to an impact energy of 200 joules.
- S5S: Safety classification for polymeric boots, including non-metallic S-level penetration resistance.
- M: Metatarsal protection with 100 J impact resistance.
- CR: Cut resistance of the upper.
- AN: Ankle protection.
- CI: Insulation of the sole complex against cold.
- HRO: Outsole resistance to contact heat.
- LG: Outsole construction intended to provide grip on ladders.
- FO: Outsole resistance to fuel oil.
- SR: Slip resistance meeting the additional requirement of the standard.
Limitations of use
The stated material resistance down to -25 °C does not by itself guarantee thermal comfort for the wearer at that temperature. Comfort depends on exposure time, activity level, moisture, socks and individual sensitivity to cold.
The HRO marking applies to brief outsole contact with a hot surface and does not make the product suitable as welding or flame-protective footwear. The boot must not be used for chainsaw work without EN ISO 17249 certification. Suitability for a specific chemical or special electrical protection requirement must be verified separately.
