From our friends at adidas:

adidas Originals are inviting everyone on Twitter to enter the chance to win a pair of Stan Smith shoes with their own personalized image on the tongue.

During the period of 13th -17th January, Twitter users will be able to enter an activation in which they can receive a personalized Stan Smith tongue graphic, and five of those entrants will receive a personalized model of the timeless shoe.

Tweet @adidasOriginals along with a photo of yourself and the hashtag #StanSmith, and you’ll enter the activation, and the chance to have you own face on the model that Stan Smith has endorsed for 40 years.
