Officers made the discovery last Friday at an express consignment facility while searching incoming freight from Bogota, Colombia, CBP said in a press release.
CBP said narcotics detector dog “Betty” alerted officers to a particular freight shipment. After x-raying the package, officers found women's boots with what appeared to be “unusually thick” arch supports, CBP said.
A closer examination revealed rectangular black packages hidden inside compartments beneath the arches. The black packages contained a white powder that tested positive for cocaine.
Investigators determined the shipment was destined to an individual in Haverstraw, a small town located in Rockland County, New York.
It was not clear if any arrests have been made in connection with the discovery.
