In addition to the Neon Yellow and Purple colorways of the Nike Air Tech Challenge that we have seen previously, Nike is working on a third colorway scheduled to release in August of 2007 as well. Although the pictured is a bit unclear and info is sparse at the moment, these ATCs look to be a White/Red/Black colorway. When we receive more info, it will be posted.
