PRODUCT FAQs

Yes, the sole carries heat resistant properties alongside its fuel and oil resistance and SRC slip resistance certification, according to STB's listed safety features.

Goodyear welted construction, where the outsole is stitched to a welt strip around the boot rather than bonded with adhesive alone, generally associated with greater durability.

Black and brown leather, both sharing the same S1 SRC certification and Chelsea boot silhouette.

Choosing the right safety footwear is about more than selecting a comfortable pair of boots or trainers. The safety rating tells you the level of protection the footwear has been independently tested to provide under EN ISO 20345, the principal European standard for occupational safety footwear.

What is EN ISO 20345?

EN ISO 20345 specifies the requirements for safety footwear fitted with a protective toe cap capable of resisting a 200-joule impact and a 15 kN compression force. Additional classifications identify further protection for different working environments.

Main Safety Ratings

Rating / Typical Protection

SB / Basic toe protection.

S1 / Toe protection, anti-static properties, heel energy absorption and fuel oil resistant outsole.

S1P / S1 plus penetration-resistant midsole.

S2 / S1 plus water-resistant upper.

S3 / S2 plus penetration resistance and cleated outsole.

S3S / Updated EN ISO 20345:2022 classification with toe protection, penetration resistance and cleated outsole.

S7 / High-performance waterproof safety footwear meeting additional water protection requirements.

Common Markings

Code / Meaning

ESD / Electrostatic discharge protection.

FO /Fuel oil resistant outsole.

SR / Slip resistance tested under EN ISO 20345:2022.

CI / Cold insulation.

HI / Heat insulation.

HRO / Heat-resistant outsole.

SC / Scuff cap abrasion resistance.

Choosing the Right Safety Rating

S1 and S1P are commonly chosen for indoor workplaces such as warehousing and manufacturing. S3 and S3S are popular for construction, engineering and outdoor work where greater protection and grip are required. If waterproof performance is important, choose footwear where this feature is specifically stated and the boot has a waterproof lining such as Gore-Tex, Cofra-Tex or Sympatex.

More Than a Safety Rating

The safety rating is only part of the decision. Consider comfort technologies, upper materials, weight, fastening systems, outsole design and whether features such as ESD protection or waterproof construction are required for your working environment.

Other Questions

Is S3 better than S1P?

Not always. S3 adds water-resistant upper requirements and a cleated outsole, making it better suited to many outdoor environments.

What does ESD mean?

ESD footwear helps control static electricity and is commonly used in electronics, manufacturing and other static-sensitive workplaces.

What is the difference between S3 and S3S?

S3S is the updated classification introduced with EN ISO 20345:2022. It reflects revised testing and terminology
while maintaining a high level of protection.
