Thanks to the high-grade materials used (real leather, for example), the S3 safety boot is water-, oil- and dirt-repellent. Its excellent fit owes a great deal to its natural orthopaedic leather lining and the interchangeable footbed insoles. The sole provides excellent protection, thanks to its acid resistance, antistatic charge, penetration resistance and contact-heat resistance up to 300 °C. The S3 safety boot is available in sizes 39 – 47.
