Though there is no doubting that the beloved Infrared colorway of the Nike Air Max 90 is the most popular, this pair might be a close second due to the unique materials and colors used on the sneaker. This sample pair hosts a white mesh upper with black, grey, and neon accents. Overall, this AM90 yields a clean and fresh new colorway that will unfortunately not be making its way to retail shelves anytime soon. As previously mentioned, this “Neon” Nike Air Max 90 is only a sample, and was recently sold on eBay.
