Safety Jogger lists the Bestrun with a breathable leather upper, a steel toe cap and steel midsole, an oil- and fuel-resistant outsole with SRC slip resistance, and anti-static protection, and suggests it for automotive, mining and oil and gas work. The metal-free Bestrun S3 gives the same rating without the steel. Each product page states its own markings.
