Safety shoes protect workers from hazards at job sites. Safety shoe standards, such as OSHA and ASTM F2413, set requirements for impact and compression resistance. OSHA enforces safety footwear regulations in the U.S. and only references ASTM F2413 since 2005. ASTM sets detailed safety standards and certifications for labeling and testing. ANSI standards once guided safety regulations, but now ASTM rules apply. Some safety shoes still show ANSI markings, even though ANSI is outdated. EN ISO 20345 remains the main safety standard in Europe.
