Releasing to select Nike accounts in the coming weeks are these two colorways in the Nike Dunk Hi AC TZ. Each features a monochromatic upper constructed from canvas, a vulcanized midsole and outsole, and an overall bland design. The first consists of a black colorway, while the second sports a grey design. The term “AC” refers to the autoclave process that was used to create the Nike Dunks midsole. Stay tuned for more information on their release as it arises.
