It's not enough just to walk, run or dance in shoes these days. First Adidas created shoes that make music as you dance. Now Nike has created a way of making artworks based on runners' tracks.

As part of the launch of its Nike Free Run+2 QS City Pack series, it commissioned design collective YesYesNo to develop software that would create dynamic paintings based on runners' feet. During a two day workshop at Nike headquarters, participants recorded their runs using Nike+ GPS. The custom software was then used to create the artworks, basing the brushstrokes on the speed, consistency and unique style of each runner.

Participants got a high res print of their art to take home, plus a pair of custom-made 'City Pack' shoes featuring their run path.
