The Opposition Bharatiya Janata Party has condemned the incident, terming it as an unestablished means of protest in a democracy.
Reacting to the incident, Congress star campaigner Priyanka Gandhi has said that 'shoe throwing is not our tradition'.
"If there is a problem, there are two ways to express it -- wrong way and the right way. This is not the right way. This is not our tradition," Vadra told reporters at Dadaur village in her mother's parliamentary constituency.
In the recent past, there have been similar incidents. In one of such attacks, a shoe was hurled at Home Minister P Chidamabaram at a press conference by a journalist.
At a rally in Kurukshtra, Congress leader Naveen Jindal was the target of a shoe thrown by a schoolteacher. The shoe missed him.
BJP leader Lal Krishan Advani has also faced a shoe attack, which missed him.
Chief Minister Narendra Modi, known for his innovative ideas, recently at a rally, came up with a unique technique to avoid such attacks. He tied up a volley ball net infront of his dais to prevent any hurled shoe from reaching him. (With PTI inputs)
