Steel Toe Caps

Safety footwear has a protective toe cap for a very good reason – to provide adequate protection against injury. Steel provides maximum protection against impact, greater cut resistance, greater penetration resistance (from a nail gun, for example) and optimum protection against rolling forces (like a forklift running over your foot). We reckon steel is the safest toe cap material available which is why all John Bull safety footwear uses only steel toe caps. We use a broad fitting 200 Joule impact resistant (a bit like dropping 20kgs from one metre) Type 1 Steel cap in all our safety styles.

Electrical Shock Hazard Resistance

When it comes to categorising safety footwear from an electrical conductivity perspective, there are three general classifications – insulating (also known as electrical hazard, non-conductive or electrical shock resistant), anti-static footwear and conductive footwear.

Electricity can be a serious workplace hazard.   Most people are aware of this and treat it with due respect.    But it’s the invisible hazard that is not typically obvious, such as on a construction site where temporary electrical cables can be severed or exposed that can be a real danger.    To help protect workers against such threats, many safety work boots are expressly designed to insulate the wearer from exposed electricity.  These types of footwear are standard attire for electrical tradespeople, but workers in other trades and occupations are becoming increasingly conscious of the need for this protection.

As the name suggests, electrical hazard footwear provides the greatest protection against electrical hazards.    We test for Electrical Shock Resistance (ESR) against ASTM F2413-11.    Products are tested at 18,000 volts at 60 Hz for one minute, with no current flow or leakage current in excess of 1.0mA under dry conditions.

It's important to know that electrical hazard protection is severely deteriorated when there's excessive wear on the outsole and heel and/or exposure to wet and humid environments.

Anti-static footwear provides a level of protection against electrical hazard situations (wall sockets not high voltage) but not as great as electrical hazard footwear.

Conductive footwear provides no protection against electrical shock.

Non-Metallic Penetration Resistant Insole

The new generation L-Protection® - composite textile insoles capable of resisting perforation by nails and other objects, even of small diameter.
Safer than steel – Protective footwear made with a PS4 insole has a level of penetration resistance exceeding 1200N (approx. 120kg). Current ISO EN 20345 specifications require resistance to 1100N.

Resists penetration even by small diameter nails and other objects – The new nail-proof fabric L-Protection® PS4 has been created using multiple layers of fabrics containing high-tenacity yarns. After plasma treatment, rendering the fibres more porous and hydrophilic, the various layers undergo ceramic treatment. Plasma treatment improves attachment and compactness of the ceramic particles, which provides a higher degree of hardness and mechanical, physical and chemical resistance whilst still retaining all the flexibility of textile.

Greater protected surface area of the foot – the ceramic fabric is sewn directly onto the upper, extending protection to 100% of the surface of the sole (as compared to 85% average protection from steel plate resistant midsoles).

Maximum Flexibility and Comfort – the use of textiles to create the protective insole allows the wearer unprecedented flexibility and comfort due to its lightweight construction, ergonomic fit and softness underfoot. The flexibility allows increased contact with ground surfaces, reducing the risk of slipping.
