I picked up the phone and called Herbert Hainer, the CEO of Adidas, and said, 'Well, it's Peace Day coming up. I think it's about time after 60 years to end this feud. How about doing something together?'

We decided that sports, lifestyle and fashion were three elements that could be mixed together to a very unique formula.

Sustainability is no longer about doing less harm. It's about doing more good.
