Designed so that they can be recycled at the end of their life and remade into new trainers, the UltraBOOST DNA LOOP forms part of Adidas' endeavours to conform to the principles of the circular economy.
The trainers will now be tested by 1,500 runners to determine how the company's Made to be Remade system of selling and returning will be launched commercially next year.
Readers aren't satisfied though, with one commenting: "Come up with a loop plan to recycle Covid-19 masks".
