Don't think it'll catch on here, fortunately

The New York Daily News has an article about politics in India:

Months after an Iraqi journalist became an international sensation after hurling both his shoes at President Bush, the shoe-throw has taken on a life of its own in India, the Washington Post reports. No fewer than four incidents have taken place in the past month, as the country undergoes its current round of elections.
In the latest incident, a 21-year-old student flung his footwear at Prime Minister Manmohan Singh at a rally in the city of Ahmedabad. The same night, at a different political gathering in Ahmedabad, a wooden sandal was tossed at prime ministerial candidate L.K. Advani. Advani was also the target of another shoe-throw earlier in the election season.
"Shoe-throwing is a real expression of the frustration of the people," Anil Bairwal of National Election Watch, a watchdog group, told the Washington Post. "But you have to consider that citizens are at a loss for what to do. For too long, they have hoped that the parties would improve themselves, be progressive, put the right people in the seats, and work for the betterment of the people. But none of that has happened."
Mundatar al-Zaidi, the Iraqi journalist who threw both his shoes at President Bush in December, is the apparent source of the craze. New Delhi journalist Jarnail Singh kicked off the trend in India, and was flooded with gifts, cash, and even marriage proposals.
While al-Zaidi is serving a year in prison following his brush with footwear fame (down from three years at his initial sentencing), no one in India has yet been jailed. Like Bush, the former US president, the Indian leaders have all managed to dodge the footwear missiles. Throwing a shoe at someone or showing the sole of a shoe is considered a sign of disrespect throughout the Middle East and South Asia.
