The Undefeated x Nike Air Max 90 “Black/Optic Yellow” is one of eight colorways in total that were released in collaboration between the Los Angeles boutique and Nike in December 2019. One of four Air Max 90’s from the collection with a black upper, this “Black/Optic Yellow” design conjures memories of a certain infectious hip-hop song from 2010. The upper is finished off in aforementioned black tumbled leather. Yellow accenting along the top of the mudguard wraps the entire shoe. An Undefeated lace dubrae can be found on the throat of the black leather tongue. Additional Undefeated detailing appears on the heel, where its Five Strikes logo is finished off in yellow for a bold look. The Air Max 90’s visible Air window in the heel is surrounded by yellow molding. The Undefeated x Nike Air Max 90 “Black/Optic Yellow” was released on December 30, 2019.
