Understanding ISO Standards

ISO Number

ISO, or the International Organization for Standardization, sets globally recognized standards to ensure the quality and safety of products, including safety shoes. Each ISO number corresponds to specific criteria that safety shoes must meet to guarantee protection for the wearer.

ISO 20345:2011

ISO 20345:2011 is a fundamental standard for safety footwear. Safety shoes complying with this standard are designed to provide protection against impact and compression. This means they can withstand an impact energy of 200 Joules and a compression load of 15,000 Newtons, safeguarding the wearer’s toes from heavy objects falling or rolling over.

ISO 20346:2014

ISO 20346:2014 is another ISO standard that focuses on protective footwear. Safety shoes meeting this standard offer protection against water penetration and water absorption. They are ideal for working environments where exposure to water or damp conditions is common, ensuring the feet remain dry and comfortable.

ISO 20347:2012

ISO 20347:2012 outlines the requirements for occupational footwear. Unlike safety footwear, shoes under this standard are not designed to protect against impacts and compression. Instead, they focus on providing comfort, slip resistance, and other ergonomic features necessary for specific work environments. This standard caters to professionals like chefs, healthcare workers, and laboratory technicians.

Choosing the Right Safety Shoe

Selecting the appropriate safety shoe involves understanding the nature of your work and the specific hazards you might encounter. Assessing the ISO number on the shoe label is vital. For instance, if your job involves heavy machinery or falling objects, safety shoes adhering to ISO 20345:2011 are indispensable. On the other hand, if your work environment is wet or slippery, opting for shoes compliant with ISO 20346:2014 is essential.


In conclusion, being aware of the ISO numbers associated with safety shoes empowers workers to make informed decisions about their protective footwear. Whether you need protection against impacts, water, or simply desire comfortable work shoes, there’s an ISO standard tailored to your requirements. Prioritizing safety at the workplace begins with the right footwear choice, and understanding these ISO standards is the first step towards a safer work environment.
