Calzado de seguridad SJ FLUX S3S MID 43

Mid-cut safety shoes engineered for professional environments where lightweight protection, all-day comfort, and ESD compliance are non-negotiable. The FLUX S3S MID 43 features a nano carbon toe cap and puncture-resistant textile midsole, delivering certified safety without the weight of traditional steel components.

Advantages

Metal-free construction reduces fatigue and eliminates conductivity risks, while the breathable mesh upper with water-resistant treatment keeps feet dry in variable conditions. The PU/PU outsole offers superior slip resistance (SR) and resistance to fuel and oil, ensuring reliable traction on industrial surfaces. ESD protection and antistatic properties safeguard sensitive electronics, and the SJ Foam footbed provides responsive cushioning for long shifts.
