In 1989, Nike Inc. designer Tinker Hatfield was asked to create a shoe for the second installment of the series, which was partly set in the then-futuristic year of 2015.

Over 15 years later, an online petition that asked for the return of the shoes caught the attention of Tinker Hatfield.

He and footwear innovator Tiffany Beers (designer of the Nike Kyrie sneaker line) worked on the redesign for approximately six years and had to restart about three times.

After thousands of hours of work, the shoes were a replica of the 1989 Nike MAG worn by Marty McFly.

The shoes feature an electroluminescent outsole, space-age materials, and a rechargeable internal battery good for 3,000 hours.
