Nike Dunk High ACThe Nike Dunk High AC is a great twist on the very popular Nike Dunk. Along with fresh new colors and materials, the Nike Dunk High AC sports a vulcanized midsole, which is very similar to the Nike Blazer. Ever since photos of this new Dunk hit the Internet, they have received fantastic reviews. The overwhelming response has been that the modification was enough to provide the Nike Dunk, originally released in 1985, a new look without completely changing its legendary silhouette.
