Foot fetish is a sexual inclination or proclivity that is defined by a significant appeal and sexual turn on towards feet, toes or feet accessories, such as shoes or stockings. The people affected with foot fetish can be stimulated sexually by the looks, smells, tastes and tactile sensations of feet. Foot fetishism is one of the widespread types of sexual inclination; people suffering from it often participate in sexual practices that include worship of feet, sucking of toes, massaging of feet, or adoration of the feet in stockings or high-heeled shoes.

A "vajankle" in a specialized context is referring to a specific kind of sex toy that combines the aspects of vagina and an ankle (vajayjay and an ankle, respectively). Normally, the vajankle comes with a anatomically accurate realistic foot and ankle with toes, arches and texture as it comes on real feet with a penetrating vagina incorporated in the ankle part. A sex toy of this type is best for individuals suffering from foot fetish who can be attracted to the vagina and enjoy penetrating a vagina or role-play of foot related sexual activity.
The vajankle can be employed in practices of masturbation, foot fetish play, or incorporation in fantasies; it allows one to have an intense and intimate sex practice for persons who develop sexual pleasure from feet and are attracted to their penetrable function. Sexual tendencies differ from person to person and the things that turn someone on, turn off another; mutual pleasure is paramount in all kinds of sexual intercourse regardless of their specialization like sex toys (vajankle) or sexual proclivities like foot fetish.
