We can’t call them whiteout, since there are a few other colors used. For example either a grey or translucent tint is added to the outsole and speckle overlays and volt is added on one of the pairs. But both use predominate white, a classic look for the Summer.
As of now the White Nike Air Tech Challenge pack consisting of the 3 and 4 low is available at select stores overseas.
