Standards for occupational and safety footwear

What do standards mean?

Anyone who decides on a professional or safety shoe from SCHÜRR can be sure that important standards are met. In concrete terms, this means that safety shoes must meet certain requirements in order to be offered and sold as such. 

Thanks to over 250 years of tradition in the shoe trade and over 40 years of expertise in the field of occupational and safety shoes, we are constantly developing new innovations in order to always be one safe step ahead. 

In the following, we would like to briefly explain what certain standard abbreviations stand for and what you can expect in concrete terms. 


Professional shoes

Occupational footwear complies with the EN ISO 20347:2012 standard. Occupational footwear is usually footwear without toe caps or with untested protective caps. The basic requirement is an anti-slip sole.

  • anti-skid sole

  • anti-slip sole
  • closed heel area
  • antistatic
  • energy absorption capacity in the heel area
  • fuel resistance of the outsole

  • anti-slip sole
  • closed heel area
  • antistatic
  • energy absorption capacity in the heel area
  • fuel resistance of the outsole
  • increased safety with regard to water penetration and absorption


Safety shoes

According to EN ISO 20345:2011, safety footwear has protective toe caps that can withstand an impact energy of 200J and a compressive force of 15 kN. However, these shoes may have other properties, such as being antistatic or slip-resistant.

Safety shoes with anti-puncture sole

Our puncture-resistant safety shoes comply with the EN ISO 20345:2011 SB, S1 or S2 standards and also have a puncture-resistant textile insert. The resistance to penetration of this insert was determined in the laboratory using a blunt test nail of 4.5 mm diameter and a force of 1100 N. Higher forces or thinner nails can increase the risk of penetration.
