Collection: Sir Safety Systems | Maximum Series Safety Shoes

High performance in harsh environments

Designed for harsh environments in the presence of hydrocarbons and chemicals, uneven terrain and particularly rough terrain. Suitable for heavy-duty applications where durability, grip, and impact protection are essential.

The New Maximum proves to be particularly robust and wear-resistant. The two-component sole made of polyurethane and rubber provides excellent shock absorption and long-term comfort.

The nitrile rubber outsole, resistant to contact heat, ensures strong grip on wet and slippery surfaces. The central sole area is abrasion-resistant and equipped with cleats to increase grip on ladders, complying with LG (Ladder Grip) certification.

The full-grain leather upper, combined with the High Durability Cap System – TPU toe cap system – ensures high product strength and extended service life.

The latex foam footbed delivers a “Memory” effect with superior cushioning and shock resistance. A thick TPU rear reinforcement provides maximum heel stability and enhanced protection for the back of the foot.
