First of all, I'm confused about where I'm supposed to reply.
But anyway, here's my word.
Psuedopodicphobia.
Fear of false feet
Okay, so that's not actually an official word that you'll find in a dictionary, but you will find that all the latin roots exist!
Psuedo= false
Podic=feet
Phobia=fear
But if you do have a fear of prosthetic feet, that is what it would be called!
