Frequently Asked Questions

What does S7 safety rating mean and how is it different from S3?

S7 is the highest level of safety footwear protection under EN ISO 20345:2011, providing significantly more comprehensive protection than S3. While S3 includes steel toe cap, penetration resistance, water resistance, antistatic properties, and slip resistance, S7 adds multiple advanced protections including electrical hazard safety (FO), heat resistance up to 300°C (HRO), ladder grip technology (LG), scuff cap reinforcement (SC), and full waterproof construction (WP). The Striver XL S7 also features a lightweight composite toe cap instead of steel. This makes S7 footwear suitable for the most extreme and hazardous working environments where multiple specialised protections are essential.

What is Ladder Grip (LG) technology and why is it important?

Ladder Grip (LG) technology is a specialised outsole design feature that provides secure footing and stability when climbing ladders. The Caterpillar Striver XL features strategically designed tread patterns and sole geometry that grip ladder rungs effectively, preventing slipping and enhancing safety during vertical work. This is essential for utility workers, electricians, construction workers, and anyone who regularly uses ladders as part of their job. The LG certification ensures the outsole has been tested and verified to provide reliable ladder traction, significantly reducing the risk of dangerous falls when working at height.

Is the Caterpillar Striver XL fully waterproof?

Yes, the Caterpillar Striver XL features WP (Waterproof) certification with a fully waterproof membrane construction that provides complete protection against water penetration. This advanced waterproofing system keeps feet completely dry even during prolonged exposure to wet conditions, heavy rain, standing water, and damp working environments. Unlike water resistant boots that only protect against light moisture, the WP rating ensures the Striver XL is suitable for outdoor construction work, utilities maintenance in all weather, and any environment where complete waterproof protection is essential throughout extended shifts.

What does FO mean and how does it protect against electrical hazards?

FO (Fuel and Oil resistant outsole) provides electrical hazard protection by creating a barrier between your feet and electrical conductivity. The Striver XL outsole is manufactured from specialised rubber compounds that resist fuel, oil, and electrical current, protecting workers from electrical shock hazards in utility work, electrical installations, and environments with live electrical equipment. This protection is essential for electricians, utility workers, and anyone working near electrical systems. The FO rating is tested and certified to provide reliable electrical hazard protection, making the Striver XL suitable for professional electrical and utility work across the United Kingdom.

Does the Caterpillar Striver XL S7 run true to size?

Yes, the Caterpillar Striver XL S7 fits true to size. We recommend ordering your regular UK shoe size. The boot provides a secure, supportive fit with the 6-inch ankle height delivering excellent stability and protection. The composite toe cap provides a more spacious toe box compared to steel toe boots, enhancing comfort without compromising protection. Customer feedback consistently reports the Striver XL is comfortable straight out of the box with minimal break-in period required. If you wear thick work socks or prefer extra room for all-day comfort in demanding conditions, you may consider ordering a size up.
