An initial investigation showed that the devices were used for massaging the feet, but the circuits could have other uses and authorities were continuing to examine them. Similar materials can be used in the construction of bombs.
The man, Faiz Mohammad (pictured), was arrested Sunday night at the Karachi airport, said Munir Ahmed, a spokesman for the airport security force. The materials were detected by a scanner.
Ahmed said each shoe contained a small circuit connected to two AAA batteries.
