When purchasing professional safety shoes, it is essential to check for the presence of the CE marking, which indicates compliance with European standards, and the EN ISO 20345 certification, the main standard for safety footwear. Also look for specific symbols such as SB (basic protection), S1 to S5 (increasing levels of protection) and additional pictograms for specific properties: HRO (heat resistance), SRC (multi-surface non-slip), ESD (electrostatic dissipation) and CI/HI (thermal insulation). All professional footwear from RAG Tailors strictly complies with these certifications, ensuring not only legal compliance but above all effective user safety.
