Uncompromising Comfort. Ultra-Wide 6E Width Fitting. The RF200 Otus Safety Boot delivers exceptional protection without sacrificing comfort. Developed through collaboration with industry experts, it features a refined anatomical design with limited seams and a generous 6E width fitting, ensuring a superior, friction-free fit for those who need a little more room without compromising on protection or performance. The BOA® Fit System delivers a micro-adjustable precision fit engineered to perform in the toughest conditions, making it faster and easier to put on and take off — even when wearing gloves. The unique cooling lining at the collar works continuously to draw heat and moisture away from the ankle area, keeping you comfortable throughout even the most demanding shifts. Paired with a breathable, waterproof construction, your feet stay dry in the wettest conditions while airflow is maintained throughout the day. The lightweight aluminium toecap shields your toes from impact without adding unnecessary bulk, and the Activ-Step® penetration-resistant insert provides a reliable defence against sharp objects underfoot — so you can move with confidence across any worksite, with ESD compliance adding an extra layer of protection in electrostatic-sensitive environments. Underfoot, a cushioned midsole absorbs impact and reduces fatigue, while the rugged rubber outsole delivers superior traction across challenging terrain — whether you're navigating gravel, mud, or loose ground. Built to go the distance, the RF200 Otus is the boot that works as hard as you do.
