At least they didn’t ​promise they’d call her in the morning.

A Queens woman thought a new pair of stockings that promised an “orgasmic” experience would rock her world — but they left her as frustrated as a selfish lover.

So now Meng Wang is suing, claiming in a new Brooklyn federal class-action suit that she was duped into believing she’d get some good vibrations from the pair of black “shaping tights” she bought at an Elmhurst Duane Reade for $7.64 after seeing an ad for the Kushyfoot product.

The Web ad features a woman sashaying around in the Canadian company’s hose cooing “highly sexually charged phrases’’ such as, “That’s the spot!” and “Oooh, yes!’’ while background singers croon “I feel super satisfied, super satisfied!,’’ the suit says.

The softly moaning woman is “literally show-stopping, causing male and female passersby alike to stop in their tracks to look at her with their mouths agape,’’ the document says.

“Towards the end of the commercial, the woman opens her eyes to find herself surrounded by a group of excited women fascinated with knowing her secret to feeling orgasmic on city streets.

“She eagerly tells them, ‘Oh, it’s Kushyfoot’ and distributes their products from her shopping bags to each of the women,’’ who then appear to be in the throes of excitement themselves thanks to the product, the suit says.

The rub is that Wang got no personal satisfaction herself after she put on her own Kushyfoot tights, according to the suit.

The ad was “supposed to indicate that she’s getting a massage through her pantyhose,’’ her lawyer, C.K. Lee, told The Post.

Unfortunately, the hosiery turned out to be “just socks,’’ he lamented.

The company has said that “by stimulating certain pressure points on the soles of the feet, the special ridged pattern on the socks helps relieve stress and promote overall well-being.”

The lawyer compared Kushyfoot’s claims to a marketing campaign by Skechers, in which that firm once said its “Shape-up” model could help tone buttocks, legs and abdominal muscles just by standing in them.

Skechers eventually settled a related class-action lawsuit for $40 million in 2012.

There are more than 100 plaintiffs in the Kushyfoot case, and they claim they’ve spent more than $5 million on its products.

Kushyfoot’s parent company, Gildan Outerwear, did not return a request for comment.
