It would have been ideal for Nike Lab to release the Nike Bruin, worn by Marty McFly in Back to the Future, on October 21st (30 year celebration of BTTF). However, Nike decided to postpone the release date last minute.

Nike Lab confirmed via Twitter that the Nike Bruin will release on October 30th, 2015. Retail will be $110.

@vauseman4ever @EdwinFabian @E46Josh The NikeLab Bruin Leather is currently scheduled to release in the US on October 30 at 10am PT.
