Cloudneo is a completely new type of high-performance running shoe developed by the Swiss company On according to the principles of the circular economy and will launch in 2022. Unlike conventional sports shoes, which are always made from a mix of materials that are virtually impossible to break down, Cloudneo is a shoe made from only one material family. Both the sole and the upper - a knitted fabric - are largely made from a high-quality, bio-based plastic called Rilsan PA 11, which, thanks to its quality, can be recycled a virtually unlimited number of times. This means that after its use, Cloudneo returns completely to the material cycle. The material thus recovered is used to create a new shoe. This model can only work if the used shoes are actually recycled. Therefore, Cloudneo is not sold, but rented out on a subscription basis called Cyclon. While the shoes go back to the manufacturer at the end of their life cycle, customers receive a new pair by return of post.
