Sneaker thieves in New York City are finding more ways to successfully steal goods without alarming security. Thieves are frequently stealing a left shoe from one store and a right shoe from another store.

“They go to Foot Locker, which has all right-sided shoes. Then they come here because we display left-sided shoes,” Salissou Mohamam, manager of SoHo sneaker store Michael K, told the New York Post.

Mohamam estimated that he loses about 50 display shoes a year to thieves, amounting to over $17,500 each year.

“They know before they steal which stores are selling which styles and sizes, left and right. They calculate before they come in,” said Jennifer Lee, 52, owner of the Sneaker Box in the Bronx.

Some store managers are trying to attach the shoes to the wall to prevent thefts.

Abbas Diallo, owner of Diallo Cap in Harlem, said he first experienced a heist in January when he caught a man in his forties trying to steal the right side of a $350 pair of Penny Hardaway Nike Foamposite.

I wasn’t paying attention. At first, I asked myself why would someone steal one shoe. Now I know.

Diallo now keeps the 15 top-selling shoes in a display case.
