Wear your employees certified safety shoes? And does the employee work safely with those shoes? It may happen that your own employee places other inlays in the safety shoe, which can restrict the protective effect of the shoes. Since 2011, the EN-ISO 20345 has been changed. This eliminates the liability of the supplier, with all the risks for the employer and employee. This standard determines that the liability of the certified shoes expires when the inlay has been changed. Certified shoes covered by the standard, should at least meet the basic requirements. These requirements consists of a protective toecap, uppers of leather Kroet (or a settlement worthy of synthetic material) and an inner lining. Note that this also applies if the safety shoe itself is certified and the sole is provided by a certified podiatrist. The combination shoe and inlay should be jointly certificated.
