UNIQUE S1PS HRO FO SR ESD – ultralight, breathable, 100% metal-free safety shoes

UNIQUE S1PS HRO FO SR ESD safety shoes combine a lightweight, sports-inspired design with a 100% metal-free construction suited to jobs involving frequent movement. The nylon net and mesh upper provides tensile and abrasion resistance while supporting airflow around the foot during extended wear.

The slim, ergonomic Nano fibreglass toe cap protects against impact and compression while contributing to thermal insulation. The PS-type NWT penetration-resistant insert weighs only 32 g—55% less than other comparable textile inserts. Its flexible construction protects the entire sole area without adding unnecessary weight to the footwear.

The ergonomic EVA Super Foam midsole provides cushioning and lasting comfort, while the rubber outsole delivers reliable grip on dry and wet surfaces, including areas where hydrocarbons may be present. HRO performance provides contact-heat resistance up to 300°C.

UNIQUE is part of the SIR 399 range, developed around exceptionally lightweight construction and a modern design inspired by sports footwear. The shoes are particularly suitable for warmer conditions, clean indoor environments, light industry, logistics and service-sector applications.
