An Instructable user / Back to the Future enthusiast took it upon themselves to great a very real version of Marty McFly’s Self-Tying Nikes from the iconic second film in the series.
As you step inside the shoe, the force sensor feels the additional pressure, adds tension to the lases, tightens the shoe and viola!
The shoes wear utilize an Arduino microcontroller and two servos in order to properly monitor your foots position in the shoe and then adjust the laces accordingly. The project is a little too expensive to hit the mainstream quite yet, but one day, perhaps by the film’s setting of 2015, this technology might actually be pretty practical.
