Federal customs officials have stopped more than 20,000 pairs of counterfeit luxury shoes from tip-toeing into the US from China.
US customs and border protection spokesman Jaime Ruiz said four shipments of fake Christian Louboutin shoes were seized on Tuesday, and another shipment was seized on July 27.
Ruiz said the shoes could have sold for a total of $18 million in the US and were very good counterfeits and will likely be destroyed.
The vaunted French designer's shoes come in an array of colours and styles, often commanding thousands of dollars per pair from well-heeled customers.
Celebrities and royalty have been known to wear Louboutins, which have red soles.
