Tested and certified

Safety shoes are tested and certified according to EN 20345:2011. EN 20345:2011 defines the requirements for safety footwear and divides them into basic requirements and additional requirements.

We are currently in the process of changing from the old to the new standard. Here you can find the overview of the changes.
