What Features Should You Look for in Safety Footwear?

Toe protection

The EN ISO 20345 standard requires toe protection capable of withstanding a 200-joule impact. This is usually provided by steel, composite or aluminium toe caps.

Antistatic protection

Antistatic footwear prevents buildup of static electricity and reduces the risk of spark discharge in the workplace.

Midsole penetration protection

Midsole protection protects against nails or sharp objects and must resist penetration forces according to the standard.

Energy absorption

Provides comfort and reduces impact stress on the heel during walking or working.

Water resistance

Footwear may include water resistant uppers or full water resistance depending on the classification.

Heat resistance

Heat-resistant outsoles can withstand temperatures up to 300°C for short periods.

Comfort

Comfortable footwear increases worker compliance and safety during long working hours.
