Portwest Steel Suede Ankle Boot S3L CI FO SR

Premium Protection in a Refined Ankle Boot

The Portwest FT72 Steel Suede Ankle Boot combines a sophisticated premium finish with serious, certified safety performance. Designed for professionals who demand reliable protection without sacrificing comfort or style, this ankle boot is built around a full cow suede leather upper that delivers both durability and a refined aesthetic suited to a wide range of working environments.

Fully certified to EN ISO 20345:2022 +A1:2024 and rated S3L CI FO SR, the FT72 meets one of the highest safety footwear standards available, offering multi-hazard protection for workers across construction, engineering, logistics, utilities, and beyond.

Serious Safety Credentials, Head to Toe

Protection begins at the top of the boot with a protective steel toecap rated to withstand 200 joules of impact and 15kN of compression — the full S3 standard for occupational safety footwear. Underfoot, a pierce-resistant composite midsole guards against sharp objects such as nails, screws, and metal shards that are common hazards on active worksites.

The S3L classification is a notable distinction: it confirms a laced ankle boot construction with a full-grain or equivalent upper, delivering a secure fit that keeps the foot well-supported throughout the working day. Combined with anti-static (A) properties and an energy-absorbing seat region (E), the FT72 addresses a broad range of occupational hazards within a single, well-engineered boot.

Cold Insulation for Year-Round Versatility

The CI (Cold Insulation) rating sets the FT72 apart from standard ankle safety boots. The sole is thermally insulated to protect against the cold conducting up through the ground, making this boot a strong choice for outdoor winter work, unheated warehouses, and cold storage environments where standard footwear would leave feet uncomfortable and fatigued.

Outsole Built for Demanding Surfaces

The mono density PU/rubber outsole is engineered to perform on challenging surfaces. Its SR (Slip Resistant) rating confirms reliable traction on both wet and oily surfaces, tested to EN ISO 20345 standards across ceramic tile and steel surface conditions. The FO (Fuel and Oil Resistant) compound resists degradation when exposed to petroleum-based substances, ensuring the sole maintains its structural integrity and grip properties over time in industrial and automotive environments.

All-Day Comfort Without Compromise

The FT72 is as thoughtfully designed for the wearer's comfort as it is for their protection. A superbly cushioned comfort footbed absorbs the stresses of prolonged standing and walking, significantly reducing foot fatigue over long shifts. The breathable mesh lining promotes airflow inside the boot, helping regulate temperature and moisture throughout the day.

A padded collar delivers a comfortable, cushioned fit around the ankle, preventing rubbing and irritation during extended wear, while the back pull-tab ensures the boot can be pulled on quickly and easily — a practical detail that matters at the start and end of every working day.

Key Certifications & Standards

The Portwest FT72 is CE certified and fully compliant with EN ISO 20345:2022 +A1:2024, carrying the following protective ratings:

Additional properties include anti-static (A) performance and an energy-absorbing seat region (E) for enhanced heel protection.

❓ FAQ Section

What does S3L mean on a safety boot? S3L is a safety footwear classification under EN ISO 20345:2022. The "S3" component indicates a full-grain or equivalent upper, a steel or composite toecap rated to 200 joules impact and 15kN compression, a pierce-resistant midsole, and water resistance. The "L" suffix specifies a laced ankle boot construction, distinguishing it from S3 boots with other fastening systems.

What is the difference between a composite midsole and a steel midsole? A composite midsole is made from non-metallic materials such as fibreglass or Kevlar, offering the same pierce resistance as steel but with reduced weight and no metal-detector interference. This makes composite midsoles particularly well-suited for workers who pass through security checkpoints or require lighter footwear for agility-intensive tasks.

Is the FT72 suitable for outdoor use in winter? Yes. The CI (Cold Insulation) rating confirms the sole is insulated against cold ground temperatures, making the FT72 a practical choice for outdoor winter work and cold indoor environments such as unheated warehouses or refrigerated facilities.

What type of leather is used in the FT72 upper? The FT72 upper is constructed from cow suede leather, chosen for its premium appearance, soft texture, and reliable durability in occupational settings. Suede leather provides a more refined finish than standard grain leather while still offering the robustness required under EN ISO 20345 standards.

Is the FT72 anti-static? Yes. The FT72 carries anti-static (A) certification, meaning it is designed to dissipate electrostatic charge safely, reducing the risk of electrostatic discharge (ESD) events in sensitive working environments.

How do I maintain cow suede safety boots? To extend the life of the FT72, brush the suede regularly with a soft suede brush to remove dirt and restore the nap. Apply a suede-specific waterproofing spray to protect against moisture ingress, and avoid prolonged exposure to standing water. Store in a cool, dry location away from direct heat sources.
