Nike has teamed with Dope Factory to make shoes that will fit in your pocket. The Nike SB Dunk Keychain is an exact replica keychain of some of the favorite Nike shoes.
There are 8 shoe keychains featured in the SB Dunk collection, and are available for a limited time. They're selling for $15 for running shoe lovers.
Implications - Keychains are items that almost everyone has. Brands like Nike have used this notion to advertise its running shoes. Not only will people be advertising the brand, but they may also want to buy the specific product on the keychain. Miniature advertising is a subtle and effective way to get a brand noticed.
