Transmitter Shoes


Shoes with a microphone, battery, and transmitter planted in one heel. They are typically given to the target as a present so that their conversations can be intercepted. The transmitter is activated by removing the white pin from the heel. This tool of espionage was actually used by the KGB in the 1960s.

The shoes Tatyana gave Granin as a present had a transmitter planted in one heel. This allowed her to monitor his every move.
