Sports-apparel giant Adidas stepped out of bounds when it decided to ship production of NBA uniforms overseas, Sen. Chuck Schumer charged yesterday.

Adidas is breaking its contract with an upstate company to make the uniforms in Thailand, and Schumer (D-NY) insisted the league press the company to keep the jobs in the country.

“The game-day jerseys the NBA players wear should be made in the US,” Schumer said yesterday outside the NBA store on Fifth Avenue.

“It is imperative that we keep the NBA-jersey operation here . . . in order to protect these good-paying jobs and to continue to promote American manufacturing.”
