Uncompromising Comfort. Ultra-Wide 6E Width Fitting. The RF220 Helix Safety Trainer 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. Engineered for those who face demanding conditions every shift, the unique cooling nylon lining works continuously to minimise heat and moisture inside the shoe, maintaining a cool, comfortable environment for your feet even in the most demanding conditions. Paired with a breathable, water-repellent mesh upper, airflow is maximised throughout the day. Meanwhile, 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. The RF220 Helix keeps you protected from the ground up, shift after shift. Every material choice in the RF220 Helix is guided by Rock Fall's Better Materials Framework, incorporating recycled polyester textiles and recycled TPU components as part of Rock Fall's commitment to reducing reliance on conventional materials.
