Talking at the Agenda Emerge event at the at the Agenda Trade Show in Long Beach, CA, Nike designer Tinker Hatfield announced that power laces would be making their debut in 2015. Nike produced a limited run of 1500 Air Mag sneakers to raise funds for the Michael J Fox Parkinson's Foundation, but that version did not feature power laces. According to Hatfield, the upcoming variant will not only feature lighting, but also functioning power laces.
A launch date was not announced, but considering that in Back to the Future Part II, Marty McFly heads to October 21, 2015, we're wishing Nike goes symbolic and decides to launch the shoes on that day.
