Understanding Safety Shoe Ratings — What S1, S2, S3, S4 & S5 Really Mean
Share
Did you know your safety shoes have specific safety ratings?
According to the EN ISO 20345 standard, safety footwear is classified into S1, S1P, S2, S3, S4, and S5, each providing different protection levels for different work environments.
Here’s a quick breakdown of what each rating means:
• S1 — Basic safety features: toe protection, anti-static sole, energy absorption at the heel, and fuel/oil resistance.
• S1P — Includes all S1 features plus pierce-resistant midsoles for sharp environments.
• S2 — All S1 features plus water resistance for wet conditions.
• S3 — Combines S2 and S1P features: water resistance + midsole protection — perfect for construction sites.
• S4 — Made from polymer or rubber, fully waterproof with all S1 features (ideal for rain or chemical areas).
• S5 — Offers the same waterproof protection as S4, but with added midsole protection for maximum safety.
Whether you’re working in construction, manufacturing, or logistics, understanding these ratings helps you choose the right footwear for the job.
