This fear can be of the persons own feet or feet of someone elses.
The fear can have different side affects such as fear of stepping in shoe shops or even shops that sell socks.
The fear can also be feet in general (Ex. looking at feet) or of looking and/or touching bare feet.
People with feet phobias are not diseased and there is nothing wrong with them.
Podophobia sufferers sometimes recieve taunts from non suffers:
Person one: Can you put some shoes on please?
Person two: Why?
Person one: Coz I have a foot phobia
Person two: hahahhahahahahahahhaha rotfl *waves feet in face*
