Nike Escalates Feud with StockX, Says Site is Selling Fake Shoes

Nike Inc. escalated its legal battle with sneaker marketplace StockX, saying it purchased four pairs of counterfeit shoes on the platform despite the company's promises that it is only marketing authentic footwear.

The world's largest athletic-wear maker asked a federal judge to let it add claims of counterfeiting and false advertising to the current trademark-infringement lawsuit against StockX.

"Those four pairs of counterfeit shoes were all purchased within a short two-month period on StockX's platform,

All had affixed to them StockX's 'Verified Authentic' hangtag, and all came with a paper receipt from StockX in the shoe box stating that the condition of the shoes is '100% Authentic,'" Nike said in a court filing Tuesday.

Nike sued StockX in February in federal court in Manhattan, accusing the marketplace of "blatantly freeriding" on Nike's trademarks and goodwill with a service called Vault NFTs.

The case is Nike Inc. v StockX LLC, 22-cv-983, U.S. District Court, Southern District of New York.
