Nike USA Inc. has filed a $126.6 million suit against Edison Chen, the founder and creative director of streetwear brand Clot, alleging breach of contract.

The lawsuit was filed on Monday in a federal district court in Los Angeles. The details of the suit are still unknown.

A search in the federal court docket system on Tuesday said proceedings for the case were “not available.” That’s not unusual in the dog days of summer when staff might be on vacation and the complaint hasn’t been uploaded to the database. Executives at Nike could not be reached for comment as the offices are closed this week for “wellness week.” A representative for Chen did not respond to a request for comment by press time.

The lawsuit was filed nearly two years after it was learned during Shanghai Fashion Week in October 2023 that Chen was partnering with Nike competitor Adidas. Adidas and Chen disclosed their new partnership at Clot’s spring 2024 show, noting that the inaugural collection for their line would be known as Adidas Originals by Edison Chen.

Clot’s partnership with Nike ran for 20 years. Their first collaborative sneaker launched in 2006. The two had been steady partners since then, until they weren’t. Little is known about why the two ended their partnership, although market rumblings at the time suggested that the deal had run its course and was set to expire anyway.

Clot, based in Hong Kong, became one of Nike’s most important partners in Asia. Their collaborations included narratives that served to educate the West on Chinese customers, such as tea ceremonies and reflexology.

Among the highs were an Air Max 1 “Kiss of Death,” which became of the most sought-after versions of the silhouette ever. It was released in 2006 for $100, and has a list price of $1,200 on the sneaker resale site StockX, although market data going back to 2017 indicates a range from a low of $230 to a high of $2,053 depending on condition and scarcity of size range.

Also popular has been a silk Air Force 1 with tear-away uppers. Clot and Nike also had a new Cortez collab — Clot x Nike “Clotez” — featuring a yellow-based upper offset by a black mudguard that was inspired by a jumpsuit worn by martial artist great Bruce Lee in his iconic 1979 film “Game of Death.” Clot also joined forces with Nike’s Jordan brand for several collaborations over the years.

And while the Nike partnership appears to be with Clot, the Adidas line — or so it was thought at the outset — seemed to have a distinct partnership just with Chen and not his streetwear brand.

Three collaborations this year now indicate otherwise, and that might be the source of some friction with Chen’s former partner.

The Clot x Adidas Gazelle line had its second drop in March, featuring a new crepe sole construction and one of two colorways making use of Clot’s signature silk pattern. An additional Clot x Adidas Gazelle dropped last year. In June, the collaboration introduced the Adidas Clot Stan Smith by Edison Chen, featuring beaded detail on the sneaker’s heel tab. And earlier this month, Chen took to Instagram to reveal the insole of the Clot x Adidas Anthony Edwards 1 sneaker. The launch date hasn’t been disclosed, but is expected shortly now that a Clot x Adidas Anthony Edwards 2 is in the works.

Chen — an actor, singer, rapper, and fashion designer — cofounded Clot Inc. with partners Kevin Poon and Billy Ip. Neither Clot nor Adidas were named as defendants in the Nike lawsuit. Representatives for Clot and Adidas did not respond to a request for comment by press time.
