These Air Max 1's were inspired by the black/pink Air Yeezy 1. The direct comparisons are pretty obvious to the average collector. Black upper, bright pink liner, green outsole to represent the glowing effect, etc. I ultimately decided to use a grey midsole over a black one just because I thought it represented the light grey toe box of the Yeezy 1 more so than a black midsole...Plus, I just thought it looked better. After all, the iD program is for us customers to design whatever we want, right? Individual Design is key!
