foot licking, foot worship, and podophilia are all terms that describe activities related to the sensual act of licking or kissing a partner's feet, often as a form of sexual pleasure or arousal. This practice can be particularly enjoyable for people who have a foot fetish because their feet carry a high concentration of sensitive nerve endings. The act of licking feet can involve gently caressing the soles of the feet, moving upward towards the toes, and then repeating the process in the opposite direction.
