All safety shoes on the European market are certified according to the standard EN ISO 20345.

There are different safety categories under this standard: SB, S1, S1P, S2, S3, etc.

But what do these abbreviations actually stand for?

SB, S1, S1P, S2 of S3: what are the differences?

Category SB

A safety shoe which meets the basic requirements belongs to the category SB (Safety Base).

SB shoes are only equipped with a protective top cap up to 200 Joules, and therefore have no anti-perforation sole, no specific walking sole and do not need to be closed at the heel.

The shoes in this category tend to be clogs.

All other categories satisfy these basic needs, plus a number of other requirements.

Category S1

S1 safety shoes meet the basic needs and also satisfy the following requirements:

• A closed heel
• Anti-static properties
• Absorption of energy in the heel
• The sole offers resistance against hydrocarbons, such as fuel, lubricant or turpentine.

S1 work shoes are best suited to activities in dry places when there is no risk of sharp objects.

Category S1P

A S1P safety shoe has all the properties of the S1 model, but also features an anti-perforation sole. This sole provides protection from the penetration of sharp objects.

However, it is not waterproof, which means this category is often used for sandals or foot protection made of breathable materials.

S1P shoes are generally used for lighter activities and indoor work, e.g. in a warehouse.

Category S2

S2 safety shoes have all the characteristics of the S1 category, but also have an additional feature.

The upper material prevents water from being absorbed or prevents water from entering the shoe.

Are you at no risk of sharp objects, but do you work in a humid environment, then the best shoes for you are the S2 model.

Category S3

Finally, we have the category S3 safety shoes.

They have the same properties as S2 safety shoes, are water-repellent and also feature an anti-perforation sole.

These shoes suit almost any working environment, and are therefore the most popular in industry and the construction.
