Lorenzo referenced a collaboration to come on his Instagram, where he wrote that he would be doing "no more Vans" and instead working with the Swoosh in 2018. It's unclear whether that comment means the project alluded to will be billed as Fear of God x Nike or Jerry Lorenzo x Nike, or whether sneakers are involved.
The Vans comment was in response to a question about whether his Fear of God x Vans sneakers would be restocking that was no doubt prompted by rumors of the product releasing again at PacSun soon. Lorenzo released sneakers with Vans in 2016 and 2017.
Early rumors have Lorenzo's Nike work releasing in April 2018. The designer had hinted about such a collaboration on his social media channels before, posting about traveling to Beaverton, where Nike's headquarters is located, and calling this picture of Virgil Abloh's Prestos "foreshadowing."
UPDATE 12/29: Lorenzo has since deleted the Instagram post where he originally left the comment screenshotted above. He also addressed reactions to the comment, suggesting on Twitter that a Fear of God x Nike collaboration is not yet confirmed.
instagram comments are not “confirmations” or “announcements”— Jerry Lorenzo Manuel (@JERRYlorenzo) December 29, 2017
Lorenzo's deleting his original statement aside, there is still plenty of evidence to suggest that he has something with Nike releasing soon. Rumors about such a collab have circulated for some time now, and the clues left on social media are ample.
