As they head into their tenth year, TEDxPortland is celebrating their first decade by raffling off 20 pairs of their ultra-exclusive Nike Air Trainer 1s. The Oregon-based series of events is certainly no stranger to Nike collaborations, as they’ve worked with the Swoosh Brand ever since their second year, creating special shoes ranging from the Air Jordan 1 to the Air Max 1. However, this is truly unique milestone, as it’s the first time that any sneakers they created have been put up for sale. 20 pairs of the TEDxPortland Air Trainer 1 are available via eBay auction, and all proceeds will go straight to the organization’s 2020 scholarship fund, covering the cost of student tickets to next year’s event. With only 200 pairs of the Trainer 1 ever having been made and the money going to a more than worthy cause, the bids are sure to pile in, so head over to eBay now to try your hand at securing a pair.
