The RF400 Dusk redefines everyday workwear by fusing a timeless, low-profile trainer look with the proven protection that makes Rock Fall trusted on site. Its classic cup-sole construction and leather upper, the streamlined toe shape give it a modern, street-ready edge while retaining the strength to handle the toughest tasks. Behind the clean design lies serious defence: a steel toe cap guards against impact and dropped equipment, while a flexible penetration resistant protective insert protects against unexpected underfoot hazards. For long shifts on unforgiving floors, a shock-absorbing comfort footbed helps reduce fatigue and maintain support hour after hour. Finally, a slip-resistant outsole ensures reliable grip across varied surfaces. This is infused with Solum Verdura™, a bio-based additive that replaces fossil-based chemistry and reduces reliance on finite resources. This not only ensures stability in challenging conditions but also increases our use of renewable feedstock and reduces our reliance of fossil-fuel based materials. Built to work hard and look good doing it, the RF400 combines Rock Fall’s hallmark durability with everyday style you can wear well beyond the job. We guide our materials choices with a clear "Better Materials Framework," supporting the use of materials with reduced environmental impact. This commitment to reducing our reliance on conventional materials is delivered using leathers sourced from a Leather Working Group certified tannery, textiles made from 100% recycled polyester and recycled TPU in the internal components that maintain the shape of the heel section. For this style, we have incorporated Solum’s bio-based pellets into the outsole. These contain plant-based feedstock, which partially replaces some fossil-fuel-based materials in the compound. This approach supports our efforts to increase the use of alternative material sources. Durable Leather Upper: Water repellent, Leather Working Group Gold rated full grain leather offers long-lasting performance that repels moisture and dirt. Recycled Post Consumer Polyester Lining Mesh: Our recycled polyester supply chain is certified to the Global Recycled Standard. Advanced Toe Protection: A steel protective toecap ensures safety without added weight. Advanced Penetration Resistant Performance: The penetration resistant protective insert provides essential on-the-job safety. Tough Rubber outsole: Flexible slip-resistant outsole produced using Solum’s Verdura™ bio-based pellets.
