TEST RUN 28. Try the adiStar or Supernova for 28 days wherever you want. If you don't like them you'll get your money back. During the campaign the dynamic ad tells a story. Just like reading someone's diary. The message is automatically updated each day. The imaginary storyteller belongs to the targetgroup, someone who tries the shoes and writes about his experiences. The TEST RUN 28 campaign is divided into two flights, the male’s view and the female’s view. On the 28th day of each flight both decide to keep the shoes.
