Nike released these sneakers, the Nike Mags, in 2016 after working on the self-lacing shoe concept for over a decade. By 2012, the shoe giant had gotten the motor technology small enough that it could actually fit within a sneaker, and just a few years later, Nike raffled off these futuristic shoes to raise over $6.5 million for Fox’s Michael J. Fox Foundation.
One of those pairs went up for sale at Heritage Auction House this week and went for a grand total of $52,500, becoming the most expensive shoe sale administered by the auction house in its history and beating the previous record by a whopping $20,000.
Other shoes have been up for auction at staggering price points in recent weeks. A pair of rare Apple sneakers from the 1990s is expected to fetch up to $30,000, and a pair of Converse sneakers Michael Jordan wore in the 1984 Olympics just sold for over $140,000.
But even with all of the other limited-edition sneakers available, McFly’s self-lacing shoes are pretty hard to beat.
