From Nike Sportswear Japan comes a Facebook app for sneaker enthusiasts. Nike Shoe Boxxxx allows you to play swapsies with virtual shoes, gaining points as you go, and build up your own customized sneaker collection.
Each player gets three virtual pairs of shoes to start with. As you learn more about the history and heritage of the sneakers, you can swap them with others to get points or acquire additional pairs, including "rare" specimens. You can customize your shoes, create your own shoe-box display and view the shoe boxes of others. The app is available in English as well as Japanese.
