Key takeaways

1. On has successfully demonstrated how to design and deliver a closed loop shoe which consumers don't need to own;
2. Sustainable materials are out there. You just need to do the research to find them;
3. Supply and logistics need to be considered based on a local city by city demand levels in order to enable a circular, closed loop cycle which maximises the positive environmental, social, and economic impact where humans are most often.
