The Rock Fall Monzonite Pro Metatarsal High-Leg Safety Boot RF540 is engineered for professionals working in high-impact, high-risk industrial environments, where advanced foot protection, ankle support and certified safety performance are essential.

Certified to EN ISO 20345 S3 SRC M, this specialist safety boot provides metatarsal (M) protection, helping protect the upper foot from crushing injuries caused by falling objects, heavy materials and equipment. This makes the RF540 particularly suitable for quarrying, construction, civil engineering, utilities, rail, manufacturing, foundries and heavy industrial operations.

The high-leg boot design delivers increased ankle coverage and stability, helping reduce injury risk on uneven ground and demanding sites. A SRC-rated slip-resistant outsole offers dependable grip on ceramic and steel surfaces contaminated with water, oils or industrial residues, reducing slip and fall hazards in challenging conditions.

A protective safety toe cap and penetration-resistant midsole deliver certified impact and underfoot protection against sharp debris and heavy materials. The durable S3-rated upper and reinforced sole construction are designed to withstand abrasion, compression and daily heavy-duty use.

Finished in a professional black colourway, the Rock Fall Monzonite Pro RF540 combines advanced metatarsal protection, stability and certified S3 performance in a trusted, high-performance safety boot for PPE-critical industrial workplaces.
