heres a sample pic that have been floating around the interwebz as of late.http://www.nicekicks.com/2011/06/air-jordan-4-whitecement-2012-sample/
i wouldnt get to comfortable with them looking like that, thats why its a sample. just experimentation and what not. they will hopefully be released in their original state minus the 'nike air' branding. same thing with the blk/cement 3s with the nubuck upper sample pic.
although i just hope that they stay true and dont go the Flu Game route.
