Unfortunately, the best-selling shoe in the world goes out of production in 2019. The Air Max 90 will be limited available in limited number of shops.
Only the all-black and all-white Nike Air Max 90 will be available throughout the year. Nike will bring back the shoes in 2020 in honor of the 30 year existence of the Air Max 90, among others with the Nike Air Max 90 OG "Infrared".
The good news is that the Nike Air Max 90 will be available at us in 2019!
