Good foot: The foot you have forward, right?
Vote here and, if possible, post if you're left/right handed. I think my good foot is my left because my right is quite duck-footed. As for if I'm right handed or a lefty, you decide:
I write with my right.
I hold knife in my left hand, fork in the right.
I kick a football with my right foot.
I throw a ball with my left.
