During the Cactus Jack Block Party event from Jordan Brand and Travis Scott celebrating the release of the "Cactus Jack" Air Jordan 4, Scott previewed a new olive colorway of the silhouette, hinting at what we can expect from the partnership in the future. 

This version sports an olive nubuck upper, mismatched black and white midsole and an olive outsole. Just like other unreleased pairs worn by Scott and associates, Nike Air branding appears alongside a "Cactus Jack" logo on the heels, suggesting the pair is indeed a collab. 

Although release details have not been officially confirmed, Pinoe77 is reporting that the "Olive" Air Jordan 4 x Travis Scott will be releasing in the future. Also seen on Scott was an unreleased purple colorway. Stay tuned for updates on a potential release
