S3 is a safety footwear classification used under the EN ISO 20345 standard. It generally indicates that the footwear provides several forms of protection for people working in environments where there may be risks of impact, compression, moisture, or sharp objects.
In simple terms, S3 safety shoes typically include:
- Toe protection: A protective toe cap designed to protect against impact and compression.
- Anti-static properties: Helps reduce the buildup of static electricity.
- Energy absorption: The heel area provides energy absorption to improve comfort and reduce impact while walking.
- Closed heel area: Provides additional protection around the foot.
- Water resistance: S3 footwear has water-resistant properties for the upper material.
- Penetration resistance: The sole provides protection against sharp objects penetrating from underneath.
However, S3 does not mean that every S3 shoe has exactly the same design or features. Additional markings may indicate other properties, such as slip resistance or specific protection against heat, fuel oil, or other workplace hazards.
When choosing S3 safety shoes, it is better to look at the working environment first. A construction worker, warehouse worker, electrician, or outdoor worker may have different footwear requirements.
