Safety Boot Ratings Explained: How to Choose the Right Pair

The right safety boots can make a major difference to protection and comfort at work. Whether you work in farming, construction, warehousing or another demanding environment, your footwear should suit the risks you face and remain comfortable throughout the day.

This guide covers the main safety ratings found across the Xpert range and the features to consider when choosing your next pair.

Safety Footwear & Regulations

Safety footwear should be chosen according to the hazards of the job. These could include falling objects, sharp materials underfoot, slippery surfaces and prolonged exposure to wet conditions.

EN ISO 20345 is the recognised standard for safety footwear fitted with a protective toe cap. Xpert products are certified to different editions of this standard depending on the model.

Established Xpert S3 products are certified to EN ISO 20345:2011, while newer S3L, S5S and S7L products are certified to EN ISO 20345:2022. Always check the individual product certification to make sure the footwear is suitable for your work.

Safety boot ratings explained

S3

S3 footwear includes a protective toe cap, antistatic properties, heel energy absorption, resistance to water entering through the upper, a penetration-resistant midsole and a cleated outsole.

Products certified under the 2011 standard do not identify the midsole type within the S3 rating itself, so check the individual product specification.

Xpert example: Xpert Defiant S3 Safety Dealer Boot, featuring a steel toe cap and steel anti-penetration midsole.

S3L

S3L is a classification introduced under the 2022 standard. It includes a protective toe cap and a non-metallic PL penetration-resistant insert tested using a 4.5 mm nail.

Xpert example: Xpert Pro Zipster S3L Safety Zip-Side Boot.

S5S

S5S is commonly used for safety wellingtons and other all-polymeric footwear. It includes a protective toe cap and a non-metallic PS penetration-resistant insert tested using a 3 mm nail.

Xpert example: Swampmaster Ranger S5S Safety Wellington.

S7L

S7L combines S3L-level protection with whole-footwear water resistance. This makes it particularly useful for demanding outdoor work in wet conditions.

Xpert example: Xpert Pro Forge Waterproof S7L Safety Dealer Boot.

What should you look for when choosing safety boots?

Protective toe cap

A protective toe cap helps protect the foot from falling or rolling objects. Safety boots can use steel or composite toe caps, provided the finished footwear has been properly tested and certified.

Composite toe caps are metal-free and can help reduce weight, while steel remains a dependable and widely used option.

Penetration-resistant midsole

If you work around nails, scrap metal or other sharp materials, choose footwear with a penetration-resistant midsole.

The product specification will tell you whether the boot uses a steel or non-metallic insert.

Slip resistance

Good grip is important when working on wet, muddy or slippery surfaces.

Footwear certified under the 2011 standard may display an SRC slip-resistance marking, while newer footwear certified under the 2022 standard may carry the SR marking.

No footwear can prevent every slip, so working surfaces should still be kept as clear and safe as possible.

Water resistance

Water-resistant and waterproof footwear are not the same.

A water-resistant upper can provide protection against occasional rain and damp conditions. For prolonged outdoor use in wet weather, choose boots with a waterproof membrane or a whole-footwear water-resistance rating.

Comfort and fit

Safety boots are often worn for long hours, so they need to fit correctly and provide suitable support.

Look for cushioned footbeds, heel support and enough room to wear your usual work socks without your toes pressing against the protective toe cap.

Dealer safety boots

Dealer boots are a popular choice in farming, construction and other trades because their pull-on design makes them easy to put on and remove.

However, the dealer boot design itself does not make the footwear safety rated. A safety dealer boot must still carry the appropriate EN ISO 20345 certification and include the protective features required by its rating.

Xpert offers both safety and non-safety dealer boots, so always check the product name, specification and certification before purchasing.

By choosing safety footwear suited to your work, you can protect your feet without compromising on comfort, durability or practicality.
