Who is the unisex safety boot Sentinel Blue (S4) for
The Sentinel Blue is designed for food processing workers, cold storage staff, fishmongers, and professionals who work in wet, cold, or hygienic environments requiring S4-rated protection. The 38 cm height keeps splashes and liquids out, while the insulated lining protects against low temperatures. The clog-resistant outsole prevents build-up of food waste underfoot, and the slip-resistant tread provides grip on wet and greasy floors. The blue colour supports colour-coding protocols common in food production facilities.
Frequently asked questions about the unisex safety boot Sentinel Blue (S4)
