More details

Discover the most fashionable safety shoe ever created! Inspired by urban looks, Nebula features a highly breathable microperforated mesh lining for continuous ventilation without compromising its water-repellent capabilities. Its line is enhanced by intertwined gel quarters, giving it an unmistakable streetwear look.

Nebula is built on a cloud-like, perforated, non-slip sole that helps the foot spread body weight evenly across the sole. This unique sole makes Nebula a must-have safety shoe. Available in grey and black, Nebula suits both men's and women's attire.

Like all our best protective footwear models, Nebula protects your feet from shocks thanks to its anti-crush shell, but also from electric shocks, punctures, and slips thanks to its anti-slip sole.

Uses

Thanks to its anti-slip, anti-electric, and anti-perforation sole, as well as its shockproof shell, Nebula is certified to ISO 20345, a European standard that guarantees that your safety shoes meet the requirements for use in environments where safety is a high priority.

Construction, hotel and restaurant, medical, mechanical, electrical, plumbing, painting, tiling, and building industries: Nebula is your best ally for protection at any time of the day.
