Physical tests
For the largest part, the material tests comprise physical tests, carried out in our own research department. Materials and components are thoroughly tested to ensure a smooth manufacturing process and the durability of our products. Here, static, dynamic, wear-and-tear and wear physiological tests are standard.
Each component and each material has different quality requirements. Here, for instance, outsoles must pass a fatigue bending test that simulates the bending load caused by rolling over while walking. In addition to various colour fastness tests, such as rubbing fastness or light fastness, leather needs to pass many other tests before we use it for making shoes. These, for instance, include tests for elasticity or tear resistance. Among other things, jewellery parts are tested for corrosion resistance.
In addition, wear samples are given to our employees to test the shoes in everyday life.
Chemical tests
We commission renowned and internationally-recognised testing institutes for chemical tests. They test materials, shoe parts and finished products to verify whether substances of concern are contained. The criteria for these tests are regulated in our Restricted Substances List (RSL), which we constantly develop further, as a member of the cads e.V. initiative. All results are documented and archived.
Our materials are tested for biocides, softeners or stabilisers in plastics, for dyes, solvents, and many other substances.
As a brand manufacturer, we are happy to comply with this high standard - because the environment and the health of customers and employees are our highest priority.
