This may be an ancient gesture from the Middle East; Psalms 60:10, speaking of some of the traditional enemies of Judah, says that "Moab is my washpot; over Edom will I cast out my shoe...." (KJV)
The shoe represents the lowest part of the body (the foot) and displaying or throwing a shoe at someone or something in Arab cultures denotes that the person or thing is "beneath them." Showing the bottom of one's feet or shoes (for example, putting one's feet up on a table or desk) in Arab cultures is considered an extreme insult. Examples include Iraqi citizens smacking torn-down posters of Saddam Hussein with their shoes, and the depiction of President of the United States George H. W. Bush on a tile mosaic of the floor of the Al-Rashid Hotel's lobby, forcing all visitors entering the hotel to walk on Bush's face to enter the hotel.
Shoe flinging or "shoefiti" is the American and Canadian practice of throwing shoes whose shoelaces have been tied together so that they hang from overhead wires such as power lines or telephone cables. The shoes are tied together by their laces, and the pair is then thrown at the wires as a sort of bolas. This practice plays a widespread, though mysterious, role in adolescent folklore in the United States. Shoe flinging has also been reported in Australia, Sweden, France, The UK and Norway.
Shoe flinging occurs throughout the United States, in rural as well as in urban areas. Usually, the shoes flung at the wires are sneakers; elsewhere, especially in rural areas, many different varieties of shoes, including leather shoes and boots, also are thrown.
A number of sinister explanations have been proposed as to why this is done. Some say that shoes hanging from the wires advertise a local crack house where crack cocaine is used and sold (in which case the shoes are sometimes referred to as "Crack Tennies"). It can also relate to a place where Heroin is sold to symbolize the fact that once you take Heroin you can never 'leave': a reference to the addictive nature of the drug. Others claim that the shoes so thrown commemorate a gang-related murder, or the death of a gang member, or as a way of marking gang turf. A newsletter from the mayor of Los Angeles, California cites fears of many Los Angeles residents that "these shoes indicate sites at which drugs are sold or worse yet, gang turf," and that city and utility employees had launched a program to remove the shoes. These explanations have the ring of urban legend to them, especially since the practice also occurs along relatively remote stretches of rural highways that are unlikely scenes for gang murders or crack houses.
Other, less sinister, explanations have been ventured for the practice. Some claim that shoes are flung to commemorate the end of a school year, or a forthcoming marriage as part of a rite of passage. In Scotland, it has been said that when a young man has lost his virginity he tosses his shoes over telephone wires to announce this to his peers. It has been suggested that the custom may have originated with members of the military, who are said to have thrown military boots, often painted orange or some other conspicuous color, at overhead wires as a part of a rite of passage upon completing basic training or on leaving the service. Others claim that the shoes are stolen from other people and tossed over the wires as a sort of bullying tactic, or as a practical joke played on drunkards. Others simply say that shoe flinging is a way to get rid of shoes that are no longer wanted, are uncomfortable, or do not fit. It may also be another manifestation of the human instinct to leave their mark on, and decorate, their surroundings.
In the motion picture Wag the Dog, a spin doctor flings shoes into trees as a part of a campaign to call attention to a fictional war hero named Sergeant William Schumann, who was given the nickname "The Old Shoe." In another motion picture, Like Mike, a character is struck by lightning in an attempt to retrieve shoes from a power line, and improbably acquires superpowers as a result.
Shoe flinging may cause utility outages, as the weight of the dangling shoes can disrupt the power line. In addition, people have been killed by electrocution while trying to remove shoes from power lines. Utilities have asked the public to call them instead of trying to remove the shoes themselves.
In some neighborhoods, shoes tied together and hanging from power lines or tree branches signify that someone has died. The shoes belong to the dead person. The reason they are hanging, legend has it, is that when the dead person's spirit returns, it will walk that high above the ground, that much closer to heaven. Another superstition holds that the tossing of shoes over the power lines outside of a house is a way to keep the property safe from ghosts. Yet another legend involves that shoes hanging from telephone wires signals someone leaving the neighborhood onto bigger and better things.
A Shoe tree, not to be confused with the shoe-preservation device of the same name, is a tree (or, occasionally, a powerline pole or other wooden object) that has been festooned with old shoes. Shoe trees are generally located alongside a major local thoroughfare, and may have a theme (such as high-heeled shoes). There are currently at least seventy-six such shoe trees in the United States, and an undetermined number elsewhere. The legend of how a particular tree came to be in Middlegate, Nevada, is quite interesting: a couple of local teenagers were spending the late spring evening hours by the tree. Being on the roadside of US 50, the loneliest highway in the US, they had a lot of time to themselves. Being the teenagers that they were, they ended up unclothed, exploring each other's anatomy. The story says that they came to an argument, and she got in the car and left, naked. The boy put his clothes on, and made a ball out of hers. The shoes, however, he did not take. He tied the shoestrings of both shoes together, and flung them into the tree, in an act of revengeful fury. Supposedly, since he had to get home without the car, he figured she should walk without her shoes. From here, the story gets fuzzier, and no one agrees on who was the next person to add the next pair of shoes to the tree. However, the legend says when the pair of shoes of this indignated boy fall, the girl will be involved in a traffic accident, not far away from there.
Since 2003 the sport has been practiced competitively in Eastern Europe. The 2004 World Championship Competition was won by Germany who is hosting the 2005 Competition at Döbeln. Apparently teams are also expected from Sweden, Estonia and Russia.
