Explosive Zone Defense: Engineered for Rig & Refinery Survival. Purpose-built for drill crews, pipeline technicians, and refinery operators confronting hydrocarbons and volatile environments. Features 100% oil-tanned full-grain leather uppers that resist sour crude corrosion, paired with SR-rated nitrile rubber outsoles delivering uncompromised grip on oily derricks and chemical-slick surfaces. Every pair complies with EN ISO 20345 S3 standards + EN 61340-5-1 ESD certification (<100kΩ resistance) to prevent static discharge ignition. Antimicrobial BactiVoid™ linings neutralize odor-causing bacteria during 14-day hitches, while metatarsal guards shield against falling valves. Where every spark could be catastrophic.
