Brand: CATERPILLAR | Model: Threshold Rebound | SKU: 40577 | Safety Standard: EN ISO 20345:2022 WP NM CT S7L HRO FO SR
The Caterpillar Threshold Rebound S7L Safety Boot with Composite Toe Cap represents the pinnacle of modern safety footwear engineering, combining Caterpillar's legendary durability with cutting-edge protective technology. Certified to the latest EN ISO 20345:2022 standard with an impressive S7L rating, this boot delivers comprehensive protection for workers facing the most demanding industrial environments across the United Kingdom. With HRO heat resistance and waterproof construction, the Threshold Rebound is engineered for professionals who refuse to compromise on safety or performance.
Designed for heavy industry, construction sites, utilities, and manufacturing environments, this safety boot features a composite toe cap providing lightweight protection without the cold transfer issues of steel. The advanced sole technology offers 300°C heat resistance (HRO), fuel oil resistance (FO), and superior slip resistance (SR), making it suitable for extreme working conditions including foundries, welding operations, hot works, and chemical handling. The waterproof membrane ensures feet stay dry during extended outdoor exposure, whilst the non-metallic construction makes it ideal for workers passing through metal detectors or working near electrical hazards.
The Caterpillar Threshold Rebound features an ergonomic design that balances robust protection with all-day wearability. The composite toe cap provides 200 Joules of impact protection whilst remaining 30% lighter than traditional steel, reducing fatigue during long shifts. Customer feedback from construction professionals and industrial workers confirms that this boot runs true to size and delivers exceptional comfort even during 12-hour workdays, making it a trusted choice for workers who demand both protection and performance from their safety footwear.

Frequently Asked Questions
What does the S7L safety rating mean?
The S7L safety rating is part of the latest EN ISO 20345:2022 standard and represents one of the highest levels of safety footwear protection available. The S7L classification includes: composite toe cap protection (200 Joules impact and 15,000 Newtons compression), penetration resistant midsole, waterproof construction, antistatic properties, energy absorbing heel, fuel oil resistant outsole, and heat resistant outsole (300°C contact). This comprehensive rating makes the Caterpillar Threshold Rebound suitable for the most demanding industrial environments where multiple hazards are present.
Is the Caterpillar Threshold Rebound completely waterproof?
Yes, the Threshold Rebound features a waterproof membrane construction (WP rated) that prevents water penetration whilst maintaining breathability. This makes it suitable for extended outdoor work, wet working conditions, and environments with regular water exposure. The waterproof rating means this boot will keep feet dry during prolonged exposure to rain, puddles, and wet surfaces, making it ideal for construction sites, utilities work, and outdoor industrial operations across the United Kingdom.
Does the composite toe cap provide the same protection as steel?
Yes, the composite toe cap in the Caterpillar Threshold Rebound provides exactly the same level of impact protection as steel—certified to 200 Joules impact resistance and 15,000 Newtons compression resistance. However, composite toe caps offer several advantages: they are approximately 30% lighter than steel, do not conduct cold in winter conditions, do not conduct heat in hot environments, are non-metallic (ideal for security checkpoints and electrical work), and do not set off metal detectors. This makes them the preferred choice for many modern industrial workers.
What does HRO heat resistance mean and why is it important?
HRO (Heat Resistant Outsole) means the boot's outsole can withstand contact with surfaces up to 300°C without degrading or melting. This is crucial for workers in foundries, welding operations, hot works environments, metal fabrication, and any industry where exposure to extremely hot surfaces is common. The HRO rating ensures the outsole maintains its integrity and protective properties even when exposed to intense heat, preventing sole separation and maintaining slip resistance in high-temperature working conditions.
Does the Caterpillar Threshold Rebound run true to size?
Yes, customer feedback from construction professionals and industrial workers confirms that the Caterpillar Threshold Rebound runs true to size. The boot features a standard fit with adequate room in the toe box for comfort during long shifts. We recommend ordering your normal UK shoe size for the best fit. The mid-height ankle design provides excellent support without being restrictive, and the composite toe cap allows for more natural toe splay compared to bulkier steel toe designs. For workers who require wide-fit footwear or have specific fitting concerns, we recommend trying the boots with your work socks to ensure optimal comfort.
