DEBRIEFING: KGB Issue Spy Shoe

Looking like a quirky prop from Get Smart, the 1960's KGB issue Spy Shoe with a radio transmitter concealed in the heel was used to monitor secret conversations. The shoe's transmitter, microphone, and batteries were imbedded in the heel of a target's shoe. A maid or valet with access to the individual's clothing would be given the job of planting the rigged shoes and activating the transmitter by pulling out a white pin from the heel. The target would then become a walking radio station, transmitting all conversations to a nearby monitoring post.
