Nike is bringing back an extremely limited colorway of the Flyknit Trainer. Featuring a two-tone Flyknit upper combining black and University Red, the shoe was originally given to the USA Track & Field team during the 2012 U.S. Olympic Trials for the London games. At the time, the production run was rumored to be limited to just 400 pairs. Plenty more will be available this time around, as the Flyknit Trainer in University Red is expected to launch in the coming weeks at nike.com and select stores. Check out detailed looks below.
