That's a good question. We completed a study with The University of Strathclyde, in Glasgow, Biomedical Engineering department which revealed that not only did our kneepads rank number 1 for reducing pressure on your knee joints (compared with competitors kneepads at that time), but they were able to spread the pressure evenly across the knee which helps further protect your knees against pressure induced injuries such as osteoarthritis, bursitis and meniscal wear and tear.
