To support the launch of its Boost line, Adidas partnered with Spotify to provide users with a personalized running playlist. Users were directed – via native ads in apps like RunKeeper – to the co-branded “Boost Your Run” website to enter their location, run duration and intensity and favorite running track. The Spotify engine modeled that track’s energy and pace to create a totally personalized playlist, plus provided popular running routes based on the user’s location. In just over four weeks, the site had 250,000 unique visitors, validating Adidas hit the mark with its passionate base of running consumers.
