Description & Specifications

Product Description

Classic protective waterproof S4 boots from the Portwest Work Shoes collection, made seamlessly from genuine PVC and nitrile. The design ensures complete waterproofing and resistance to fuels, oils, greases, and fatty substances. The boots feature steel toe protection with 200 J impact resistance and soles with anti-slip and anti-static properties. Additional features include energy absorption in the heel area and reinforced ankle and heel protection, facilitating easy wearing and removal.

Main Features

  • Steel toe protection resistant to 200 J impact
  • Waterproof, seamless construction — 100% protection from water
  • Anti-slip and anti-static sole resistant to fuels and oils
  • Energy absorber in the heel area to reduce fatigue
  • Reinforced ankle protection
  • Plastic heel support for easier removal
  • Dual density combining PVC and nitrile

Materials and Construction

The upper and sole are made from PVC/Nitrile using dual-density technology, combining flexibility and durability with chemical resistance. The seamless design eliminates leak points, and the materials used increase resistance to fuels, oils, greases, and fatty substances.

Standards and Certifications

Standards: EN ISO 20345:2022 (class S4), EN 13832-3:2018.

Testing and Certification: Intertek Italia Laboratory (Notified Body No: NB:2575), certificate ITASLNB23024645.
