Sydney Sweeney had a ball at the Knicks game.

The “Euphoria” actress snagged a ticket to Wednesday night’s NBA Finals Game 4 at Madison Square Garden — and her toes were ready for tipoff in a pair of vintage Manolo Blahnik orange sandals adorned with miniature basketball charms.

Sweeney, 28, showed off the shoes on her Instagram Stories, zooming in on her ballet-slipper-pink pedicure peeking out from beneath the tiny charms.

The heels are a reworked style created by Sororité — a designer vintage dealer with fans like Bella Hadid and Olivia Rodrigo. The shop has also made versions customized with tiny tennis balls and baseballs, and has a collection of basketball heels like Sweeney’s dropping online later this afternoon.

Sharp-eyed fans may recognize the shoes: they’re nearly identical to a pair Jordyn Woods had in her potential shoe lineup for Game 3, when the model weighed the reworked Manolos with Christian Louboutin mules before settling on a new offering from her own brand: orange faux ostrich stilettos meant to channel her now-famous lucky clutch.

Sweeney also shared a selfie with Braun on her Stories, writing “This was an emotional rollercoaster” — a fitting description for a game that saw the Knicks erase a 29-point deficit to stun the San Antonio Spurs 107-106 and take a commanding 3-1 series lead.

She paired the sandals with jeans, a white low-cut top and an oversized Knicks leather jacket.

The couple sat a few rows behind Taylor Swift, who was courtside in a “Stevie Knicks” T-shirt with friends Alana and Este Haim. They showed tons of PDA and the former music manager revealed in a comment on the Post’s Instagram that it was the “Euphoria” star who surprised him with tickets to the game.

The basketball-themed Blahniks are par for the course during a playoff run that’s spawned its own unspoken dress code. High-rolling fans have been showing up in custom Hermès bags and $27,000 diamond basketball bag charms, with courtside tickets going for half a million dollars.

Luxury travel consultant Erica Jackowitz told Page Six Style the MSG front rows have become “the most viewed runway in the world.”
