Don’t let your eyes deceive you: those aren’t two separate pairs of shoes. Rather, they are one very special collaboration between cyclist and Creative Director of Intersection Magazine, Yorgo Tloupas and Nike as part of the City Tempo/CTRS/Livestrong collection, in which 8 cyclists from 8 different cities choose a colorway for the Nike City Tiempo shoe. The shoes, which are all black under natural light, but when exposed to car headlight or the flash of a camera becomes white with a black swoosh. This design is not just interesting from a design perspective but is also very useful for those who tend to peddle at night, when they can be  easily missed by traffic.
