A retired FDNY hero who toiled at Ground Zero in...

It was a shoo-in for disaster.

A marketing stunt by Adidas and AriZona Iced Tea that promised dirt-cheap limited-edition shoes descended into chaos Thursday morning — with one person carted away in an ambulance and two arrests — when sneakerheads started rioting after learning they might not get their kicks fix.

Adidas and AriZona were selling a limited-edition crossover shoe bearing the drink company’s branding for just 99 cents, which attracted hundreds of rabid collectors to descend on a two-day pop-up market at Bowery and Rivington.

But the first shoes hadn’t even been doled out when disorder erupted a little before 9 a.m., after some of the people on line learned they might not get a pair of the 1,000 limited-run sneaks.

“It was insane. Nobody got anything,” witness Lucas Crespo, 24, told The Post. “People got robbed, mobbed and pushed.”

At one point, someone lobbed a glass bottle, striking a girl in the face.

“She was covered with blood,” Crespo said. “She was there since 1 a.m. and she had to leave in an ambulance.”

The FDNY said it picked her up at 9:47 a.m. with non-critical injuries.

Two people were arrested and the NYPD eventually ordered everyone to leave.

One witness slammed the shoe and drink companies for over-hyping the event.

“They like to create hype. They promote for days and weeks to create attention — knowing that New York is barbaric, people are going to step on each other,” fumed Ty Campbell, 31.

Adidas cancelled the pop-up planned for Friday.

“Right now, we’re working the NYPD to make sure everyone is safe,” spokesman Andres Paz told The Post, without giving details of what safety measures they are taking.

AriZona reps did not respond to requests for comment, but the company tweeted an apology following the mayhem.

“Thanks to our loyal fans that came out to support our partnership with Adidas. Due to overwhelming demand and safety concerns, the NYPD shutdown our pop-up. We sincerely apologize to all our fans that waited in line. We are actively working to remedy the situation,” the company wrote.
