Lightweight comfortable and metal-free S3S mid-cut
The FLUX S3S MID is a durable, low-cut safety shoe engineered for comfort and protection in light industrial settings. The synthetic nubuck upper offers strong abrasion resistance and reliable water-resistant protection (WRA). A recycled mesh lining improves breathability and moisture control for extended wear. The nanocarbon toecap ensures lightweight impact resistance, and the metal-free puncture-resistant midsole enhances flexibility and underfoot safety. The PU outsole provides superior grip and traction on dry, wet, and extremely slippery surfaces. Designed for assembly, automotive, catering, food & beverage, and logistics applications, the FLUX S3S MID combines advanced materials, ergonomic design, and dependable performance.

Key features

Metal free
Metal free safety shoes are in general lighter than regular safety shoes. They are also very beneficial for professionals who have to pass through metal detectors several times a day.

Slip resistance (SR)
Replaces the previously used term of SRA+SRB=SRC. SR means the slip test has been executed on tiles contaminated with soap and with oil.

Electrostatic discharge (ESD)
ESD provides the controlled discharge of electrostatic energy that can damage electronic components and avoids risks of ignition resulting from electrostatic charges. Volume resistance between 100 KiloOhm and 100 MegaOhm.

Scuff cap (SC)
Separately tested material to cover the toe cap area to reduce abrasion of the upper material (e.g. during kneeling operations) and extend usability of the safety shoe.

Breathable upper
Increased moisture and temperature management for extended wearer comfort.

Nano carbon toecap
Ultralight high-tech material, metalfree with no thermal or electrical conductivity.
