A Manhattan saleswoman who pocketed $10,000 a month to peddle pumps for an up-and-coming shoe company turned out to be quite a heel, according to a $1 million lawsuit.

Alepel was launched by fashionista and former ­architect Adriana Levy in 2013, and the brand’s bold designs include a narrow strip that runs down the backs of the shoes and along the bottom of their distinctive chunky soles.

Angelique Thompson, a California resident who had an office in Midtown, told the Florida-based company she could sell 10,000 pairs of its shoes in a year and portrayed herself as “having the appropriate contacts in many of the major chain stores,” court papers said.

They agreed to pay Thompson $10,000 a month and shelled out another $9,710 just to get Thompson samples of their product, so she could sell the shoes in North America and Europe, Alepel says in its Manhattan Supreme Court lawsuit against Thompson.

But just three months into the 2014 deal, Thompson hadn’t reported any sales, let alone the 4,000 pairs of shoes she pledged to sell in the first six months, the company claims.

But Thompson “completely neglected her obligations” and sold a pitiful 94 pairs of Alepel shoes, all while pocketing $40,000 in pay, according to the legal claim.

The other shoe dropped on the company when it asked her to return the sample shoes, and she replied that she couldn’t because they’d been stolen out of her car in Las Vegas.

“Thompson has yet to explain why Alepel’s merchandise was in a vehicle in Las Vegas, Nevada,” the company quipped in court documents. It seeks $1 million in damages.

Thompson did not return a message seeking comment.
