How it started

In the year 2000 sailmaker René van Rijn went to his doctor with chronic knee complaints. He was referred to Geert Kaal, physiotherapist and specialized in knee and back complaints. After ten treatments, René’s knee problems disappeared, but after 3 months he returned with exactly the same physical symptoms. But now so bad that he could no longer work on his knees. René had already bought and tested several knee protectors, but nothing helped him to prevent his knee and back problems. This was the moment he asked Geert: “Can you help me develop a knee protector that allows me to continue working?” After studying the “knee position” dozens of people were put into “form-foam” to find the right ergonomic shape. After this, several prototypes were made and tested by various ‘knee sitters’ such as carpet layers, parquet layers, tilers and construction workers.

The idea was born, we must develop a knee protector where the pressure is not concentrated on the knee – but is distributed across the lower leg. In addition, it must be lightweight, breathable, and water-resistant. Five years later, the first model was ready for the market. Geert & Rene rented the smallest stand at a construction trade fair and after two days they were sold out. The rest is history, with millions of users who enjoy FENTO in more than 25 countries all over the world.

We want professionals to enjoy wearing FENTO and to enjoy their lives after the day is done. Leading an active live at home, playing with the (grand) children, biking, running and walking. That’s what we do it for.
