Product description

RF540 Monzonite– Classic High Cut Performance Boot

Built to Endure, Built to Protect: Don't let long hours on your feet slow you down. The Monzonite Safety Boot combines unrivalled protection with maximum comfort. Its fibreglass toe cap shields your toes from a minimum of 200 joules of impact, offering peace of mind on any worksite, while the Activ-Tex® waterproof membrane keeps your feet cool and dry in the most treacherous conditions. The exclusively crafted para-aramid anti-puncture protective midsole developed by Activ-Step® Footwear Components, adds an extra layer of defence against sharp objects you might encounter throughout your workday. Its ankle-supporting design ensures stability on ladders and uneven surfaces. Constructed with our Internal Metatarsal Protection Technology that became world first technology for the Rock Fall brand, ensuring not only your toes and underfoot remain protected but your metatarsal bones also benefit from next level protection. The aggressive FORCE10® outsole provides superior traction in challenging terrains, whether you're navigating gravel, mud, or ballast. Our FORCE10® Scuff cap provides ultimate protection and durability to the toe area, even in the most testing conditions. Our IMPACTSHIELD™ internal digging plate gives extra underfoot protection for heavy workloads, allowing you to tackle your toughest jobs. Conquer the toughest jobs with confidence and comfort thanks to the durable construction and supportive design. We’ve even added a strong side zip for quick release! We use leather from a tannery audited & certified by the Leather Working Group (LWG). The Leather Working Group helps tanneries improve their environmental and social performance through auditing and certification.

A serious boot, that is amongst our most widely used styles within the Rock Fall Portfolio, from Offshore Companies in the Gulf to one of Europe’s largest Infrastructure projects in the United Kingdom.

Durable Leather Upper: Water repellent, LWG GOLD rated full grain leather offers long-lasting performance that repels moisture and dirt.

Waterproof Construction: An Activ-Tex® waterproof membrane bootie, using 60% recycled post-consumer polyester, keeps your feet dry in wet conditions and at the same time, contributing to a reduced environmental footprint.

Advanced Protection: A fibreglass protective toecap ensures safety without added weight; FORCE10® Scuff cap provides ultimate protection and durability to the outside toe area. The exclusively crafted para-aramid anti-puncture protective midsole developed by Activ-Step® Footwear Components provides essential on-the-job safety and our IMPACTSHIELD™ digging plate offers increased protection from underfoot injury.

World First Internal Metatarsal Protection: Our world first non-metallic internal metatarsal protection ensures flexibility while protecting the delicate metatarsal bones from an impact of 20kg falling from a height of 50 cm, equivalent to 100 joules of force.

Tough Solid Nitrile Rubber outsole: Our FORCE10® outsole provides maximum protection in the toughest conditions, with a high level of durability and heat resistance.

Side Zip: Quick release for when time is critical.

We strive to use high-quality materials that prioritise durability and include recycled content where possible.
