Common running shoes no longer provide sufficient cushioning after a few hundred kilometers. Such a shoe is not only unhealthy for the joints, but also makes running exhausting. So even though the shoe is still in top shape, thousands of pairs are thrown away every year. The running shoe promises better performance, fewer injuries and reduces waste to a minimum. The individual parts can be freely assembled and replaced at the end of life. It’s time to revolutionize the footwear industry.
