【New, Unused】 This is a collaboration sneaker between Nike and the Dutch denim brand Denham. It's new and unused, as it has been stored in its box since purchase. I collected these as part of a collection, but I've decided to sell them. From the following website: The original color "INFRARED" of the AIR MAX 90 was chosen. Denim material is used for the upper, and the sole parts and tongue logo are colored with the characteristic "INFRARED". Model/Series...AIR MAX Model/Product Name...AIR MAX 90
