Looking to give the Nike ACG Lupinek a modern look and feel for the Fall season, Nike decided to give it a Black Flyknit upper that completely changes the aesthetics of the shoe. The ACG model comes in an all-Black upper done in Flyknit fashion. Although it is considered a Flyknit model, the shoe still has hits of leather in areas such as the toe, mudguard, tongue and lining and heel, which is a good idea since it is an ACG model and you do need that extra protection and durability. Below you will find a natural motion sole unit with added grip. 3M hits on the heel round out that main features on the shoe.
