The original MAG.
The original Nike MAGs worn by Marty McFly in Back to the Future II in 1989 will be up for auction at Comic-Con. The futuristic power-laced sneakers saw a special release last year to raise money for the Michael J. Fox Foundation which saw pairs being auctioned up to the price of $200, 000 USD.
Although the original are not as pristine as the 2016 versions, this is a one-off piece of history and is expected to be bought for a very high amount.
