When do you need an S4 boot?
Once your feet are actually standing in water, no leather shoe keeps them dry. An S4 boot is moulded from a single piece of rubber or PVC and is therefore fully waterproof, with a protective toe cap against 200 joules. Typical work: rinsing and cleaning, agricultural work, fish processing and temporary work in flooded spaces.
Rubber, PVC and comfort
Rubber is more supple, warmer and more pleasant for long days; PVC is more affordable and resistant to many chemicals. Always wear moisture-wicking socks and let the boots dry at room temperature after use. If there's also shards or nails on your work site, choose an S5 boot with a penetration-resistant sole.
