The design story of Nike Sportswear for Fall/Winter 2011 is just about technical materials or newest manufacturing methodology. There are other aspects as well, like these Dunk AC Premium.  Part of the Tier-Zero product line, the Dunk AC Premium sports a lux leather upper in all-tan or all-black color schemes.  Both rest on a vulcanized all-white outsole for a clean, streamlined look, making them fashionably appropriate for all types of occasion later this year.  No information on exact release information as of this moment but stay tuned!.
