When sourcing white safety shoes, the most critical standard is EN ISO 20345:2011 (or the updated 2022 version), which specifies that the shoes must have a toe cap capable of resisting a 200-joule impact. For the U.S. market, ensure compliance with ASTM F2413-18. Since white safety shoes are often used in food processing or medical environments, look for S2 or S3 ratings, which guarantee water resistance and fuel oil resistance. Additionally, verify CE marking for European exports and UKCA for the UK market.
