For the development of the FENTO knee protectors, dozens of people were given a plaster mould to find the correct ergonomic shape. Various prototypes were made, and tested by different types of ‘kneeling workers’. The best solution proved to be a knee protector that distributes the load across the knee as well as the lower leg. The knee protector also had to be light as a feather, breathable and hard-wearing. And that is how the FENTO knee protector was born.
