NEW YORK (CNNMoney) — Nike sent a pair of self-lacing sneakers to Michael J. Fox Wednesday to mark the day that Marty McFly and Doc Brown arrived in the future — October 21, 2015 — in "Back to the Future II."
The shoe company said it was making additional pairs to be sold in support of the Michael J. Fox Foundation. The foundation does research into Parkinson’s disease, which Fox was diagnosed with in 1991.
Sneakerheads and "Back to the Future" fans had been hopefully anticipating that Nike would produce the shoe for commercial sale.
Word of the shoe got out when Fox tweeted today, "The letter I received from Tinker today. Thanks @Nike."
Tinker appears to be Tinker Hatfield, a Nike shoe designer.
In his note, "Tinker" writes, "As the first most celebrated wearer of the Nike Air Mag, we wanted you to be first to receive a ‘living pair.’"
The note, which includes a drawing of Fox holding the new sneaker, went on to say, "In addition to your personal pair we’re creating more pairs for support in aid of the Michael J. Fox Foundation." The note says those shoes will be available in 2016.
An auction of "Back to the Future" shoes in 2011 raised $9.4 million.
The speculation about the shoe went into high gear Tuesday night with a cryptic tweet from the shoe company to Fox that said, "See you tomorrow."
The "tomorrow" that the company was talking about is Wednesday, October 21, 2015, or the day that Fox’s Marty McFly travels to the future in 1989’s "Back to the Future Part II."
"The first pair of self-lacing Nike Mag shoes is in New York City," Nike told CNN.
The company wouldn’t go into details about the location of the shoes or even if the shoes were going on sale.
In the film, McFly tries on a pair of grey Nike high-tops, known as "Nike MAGs," that to McFly’s surprise self-lace.
"Power laces! Alright!" McFly says in the film.
Nike’s tweet had fans exclaiming "great Scott!" on social media over the possibility that the shoes are on the way.
Since the film’s 1989 release, the shoes have become a longed-for item for the movie’s fans and sneaker enthusiasts.
The company patented an "automatic lacing system" in 2008.
