A drug mule tried to put the "sneak" in sneakers last week -- but got busted at JFK with $90,000 worth of heroin in 3 pairs of Nike Air Force 1s ... officials say.
U.S. Customs and Border Protection says the drug mover was on a flight from the Dominican Republic -- and when he got to the inspection, officials noticed his shoes were unusually heavy.
In the end, officials say they found 3 POUNDS of heroin hidden in the kicks ... with an estimated street value of $90,000!!!
The perp was arrested and handed over to Homeland Security -- and now faces federal drug smuggling charges.
