A running shoe like a sock, made like a toy and yet capable of breaking records. The Swiss company On, in which Roger Federer also has a stake, has revolutionized the way sports shoes are made with Lightspray. The best thing about it: in contrast to the conventional method, 75 percent of emissions are saved.

It is one of the most famous stories in the history of the Olympic Games. In 1960, Ethiopian Abebe Bikila won the marathon in Rome running barefoot. Today, such a thing is completely unthinkable. The search for the right shoe is a scientific tinkering. When carbon soles appeared a few years ago, the top times in the endurance sector suddenly became even faster. Nike, Adidas and the like are trying to outdo each other.
