Cool Hunting has a great article about the Nike iD Store on 255 Elizabeth Street in Manhattan, NY. Currently, the only way to get inside the store is by invitation only.
Colors and materials not on the site, however, are available solely at 255. The Air 180, Rift, Presto, Free and FC, have a 14-color palette to choose from and there are suede and Nubuck options on several of the models, all full-grain, high-end Inca leather. Currently, only one model is exclusive to the shop, the Waffle Trainer II.

These are the Nike Air Force 1 Harlems. Using laser technology that Nike loves, the map of Harlem is lasered onto the upper. They should be already released in the States. Pictures from Kix Files.
