The Rock Fall RF125 Alder S3S ESD Safety Trainer combines lightweight workplace protection, lasting comfort and carefully selected bio-based and recycled materials. Designed for modern industrial environments, this sporty black safety trainer is ideal for professionals who need dependable foot protection without the weight and bulk of a traditional safety boot.

Certified to EN ISO 20345:2022 S3S FO SR and BS EN 61340-4-3:2018 ESD, the RF125 Alder provides protection against impact, underfoot penetration, slips, fuel oil and electrostatic discharge. Its non-metallic construction, breathable upper and responsive cushioning make it particularly suitable for manufacturing, electronics, automotive, warehousing and logistics.

Breathable TENCELâ„¢ upper

The highly breathable knitted upper incorporates TENCELâ„¢ Lyocell fibres, which are derived from wood-based raw materials. These fibres help manage moisture and support a naturally dry, comfortable feeling around the foot.

A water-repellent treatment provides additional protection in changing working conditions, while the lightweight and flexible construction allows the trainer to move comfortably with the wearer. The internal lining contains recycled polyester, reducing reliance on newly produced synthetic material without compromising everyday durability.

Lightweight, non-metallic protection

Protection is provided by a strong yet lightweight fibreglass safety toe cap, helping guard the toes against workplace impacts and compression. An Activ-Step® penetration-resistant protective insert provides flexible underfoot protection against sharp objects.

The protective components are completely non-metallic, helping reduce the overall weight of the footwear and supporting greater flexibility. This makes the Alder a practical choice for employees who cover long distances or remain on their feet throughout a shift.

Certified ESD safety trainer

The Rock Fall Alder is certified for use in electrostatic discharge-sensitive environments. Its ESD technology helps dissipate static electricity in a controlled manner, reducing the risk of accidental damage to sensitive electronic components and equipment.

This makes the RF125 particularly suitable for electronics manufacturing, assembly areas, automotive production, laboratories and other controlled workplaces where electrostatic charge must be managed.

Cushioned BLOOM® foam midsole

The responsive midsole incorporates BLOOM® algae-derived foam as part of its formulation. This bio-based material helps reduce reliance on conventional fossil-fuel-derived components while delivering the cushioning required for demanding working days.

The shock-absorbing midsole helps soften repeated impacts when walking on hard industrial floors or uneven outdoor surfaces. Its responsive construction provides energy return and rebound, helping reduce foot fatigue during prolonged periods of movement or standing.

Activ-Step® anti-fatigue footbed

Inside the trainer, the removable Activ-Step® bio-based footbed delivers additional cushioning and support. It incorporates BLOOM® algae-derived material alongside a recycled polyester sock liner.

The anti-fatigue design helps absorb impact, support the foot and improve comfort throughout extended shifts. Moisture-managing materials also help create a fresher internal environment.

Durable, slip-resistant outsole

The EVA and rubber sole construction balances flexibility, rebound and long-term durability. Its rubber outsole incorporates Solum Verdura™ bio-based additive technology, supporting Rock Fall’s commitment to using carefully selected materials with a reduced dependence on conventional fossil-fuel-derived alternatives.

The outsole has achieved an SR slip-resistance rating, providing dependable traction across a variety of workplace surfaces. It is also resistant to fuel oil, making the trainer suitable for automotive, manufacturing and industrial applications.
