When sourcing industrial-grade footwear, prioritize ASTM F2413-18 or EN ISO 20345:2011 standards for safety toes (steel or composite). Ensure the factory uses Full-Grain Leather for durability and water resistance. Key technical components include Goodyear Welt construction for longevity and resoling capability, and T1220 or T1260 rubber outsoles for superior slip, oil, and abrasion resistance. Additionally, verify the integration of EASE comfort technology or high-rebound EVA midsoles to reduce worker fatigue.
