Nike teamed up with LA-based sneaker boutique Undefeated for this December 2019 renovation of Tinker Hatfield's Air Max 90. Circumventing the AM90's typical mixed-material makeup, this take on the classic sneaker uses only premium leather to craft its upper. Undefeated s tally logo is located on the heel, heightening brand awareness for this collaboration. Hits of Blue Fury break up the otherwise all-white look, finding space on the branding, perimeter, Max Air unit and outsole.
