While early images have yet to surface, leaks provided by zSneakerheadz suggest that the latest style will mirror the color blocking of the "Classic Green" Air Jordan 4 that released back in 2004. The color description indicates that the shoe will be executed in a white-based upper and paired with Pine Green and Metallic Silver accents. Note that the pair pictured above is the aforementioned "Classic Green" colorway from '04 courtesy of Flight Club.
As of now, official release information for the upcoming "Pine Green" Air Jordan 4 has yet to be announced by Jordan Brand.
