Opal S1PL high safety sneaker - Redbrick
The Redbrick Opal High is the eco-conscious choice for those who want to work safely while caring for the environment.

The breathable upper keeps your feet fresh, the composite toecap protects against impact, and the textile anti-perforation midsole (PL) guards against sharp metal objects up to ø 4.5 mm. Thanks to the slip-resistant outsole, you’ll always have solid footing, even on slippery floors. Please note: S1PL shoes are not water-repellent, making them ideal for dry, indoor workplaces.
