Most people put one in front of the other as a most basic way to get around, though they often come in handy to kick a ball, ride a bicycle or dance a jig — maybe even walk a tightrope.
But in Asia, feet are far more than just the two pins that keep us upright and get us from A to B — they can lead people into a cultural minefield.
In India, touching another person’s feet is perceived as a sign of respect for their knowledge and experience, usually reserved for family elders and teachers and parents.
Feet also play a prominent role in Indian wedding ceremonies. During Hindu weddings in western India, the bride’s parents wash the groom’s feet. In eastern India, the bride dips her feet in a mixture of milk and a red dye before entering the groom’s house, leaving red footprints on the floor.
Hindu and Muslim women decorate their feet with henna in the run-up to weddings, and Hindu brides traditionally wear toe-rings after the wedding to signify their married status.
In Thailand, it is the opposite — feet are considered fine for walking, but that’s about it.
“It is disrespectful to point your feet at seniors or put your feet on a table or step on books,” said Suchitra Chongstitvatana, director of the Thai Studies Center at Bangkok’s Chulalongkorn University.
“It’s been a taboo in Thailand for a long time and it still is. It shows the delicacy of Thai people,” she said.
Japanese people have traditionally taken off shoes at home. Why? Some experts say the use of tatami floor mats, regarded as valuable and sacred, is a major reason for the custom.
Others say it’s mainly because of sanitation in a country where humidity is relatively high and taking shoes off can help keep feet dry.
Some Japanese car drivers even ask passengers to take off their shoes, while many businesspeople change into slippers in the office. There is nothing unusual about leaving shoes at the door of a restaurant when you go in.
For hundreds of years, many women in China were forced to endure the painful practice of foot binding to make their feet smaller — a key criteria for beauty and marriageability in imperial days.
The custom was abolished when the Communists took power in 1949. China’s modern-day interest in feet centers around massage.
Virtually every street in major Chinese cities boasts one or more foot-massage outlet, an industry that is increasingly popular because of the traditional Chinese belief in the healing qualities of a good foot rubdown.
Practitioners of Chinese traditional medicine say the foot has a multitude of pressure points and that manipulating them — while loosening up those tired soles — promotes health in other parts of the body and helps prevent illness.
The China Foot Massage Industry Association said in 2008 that the foot massage sector was raking in 1 billion yuan (US$$152 million) every day — yet another leisure practice benefiting from rising incomes in China.
Many outlets will typically offer a 90-minute foot massage for as little as 80 yuan, which includes a herbal foot soak followed by a powerful and often wince-inducing kneading of the soles and toes.
The industry is also marching on in Hong Kong.
Reflexologists believe there is a direct link between feet and all major organs. And if it hurts in one place, it’s a telltale sign there could be something wrong elsewhere in the body.
