Prevalence of foot fetishism

Fetishist behavior is unlikely to be reported; its prevalence is unknown.[2] However, it is one of the most common fetishes in males.[3]
An informal study was conducted in 2001 to determine the prevalence of certain fetishes. More than 72,000 Adult-oriented Yahoo! Clubs (now Yahoo! Groups) were identified, of which 741 were found to be foot-related. By assuming that the people who used Yahoo! Clubs represented a balanced cross-section of the world's sexual preferences, it was estimated that 1.14% of people had foot fetishes.[4]
The practice of toe sucking (an aspect of podophilia) gain global attention when in 1992, surreptitiously taken photographs of John Bryan, an American financial manager, sucking on the toes of a topless Sarah Ferguson, Duchess of York (then separated but still married to Prince Andrew, Duke of York) were published in the English tabloid newspaper The Daily Mirror. The Duchess was exposed to widespread public ridicule and contributed to her further estrangement from the British Royal Family and later divorce from the Duke of York.[5]
