Anyone know anything about these shoes?

The article you provided says that the shoes were "Native American inspired," not for sale only to Native Americans. It also says, "Nike has in recent weeks been slowly revealing and releasing its Native American inspired collection for Spring 2008." So these shoes were released a few years ago. However, it also says, "Unfortunately for most of the world, these kicks will be an Asia Exclusive release." So these shoes were only released in Asia. After searching, the other articles I found online had basically the same information as the one you provided.
