Safety. ESD. Lightweight. The RF125 Alder safety trainer features a highly breathable upper incorporating TENCEL™ Lyocell fibres, designed to help keep feet cool and comfortable throughout the working day. TENCEL™ Lyocell fibres are derived from wood-based raw materials. ESD compliant, the built-in technology helps dissipate static electricity, supporting the protection of sensitive electronic components in the workplace. The lightweight design promotes ease of movement, while the anti-fatigue footbed delivers comfort, cushioning and energy return throughout the day. The sole construction incorporates selected bio-based material technologies. The midsole contains BLOOM® algae-derived foam as part of the material formulation, incorporating bio-based content within the midsole compound. This is combined with a rubber outsole incorporating Solum Verdura™ bio-based additive technology, supporting reduced reliance on conventional fossil-fuel derived materials.
