IMO I don't really like boxing as to say a martial art with kicking. Why use a punch, when you can generate more power and have greater reach with a kick. Punching is most effective short range, but foot movement ties it all together. If your out of their range they can't hurt you. Simple. Some argue that punching is faster but I have seen some great martial artists that can kick faster than people can punch, plus their flexible so they can go straight for the head and KO someone first kick.
I'm not encouraging violence here, just saying that the martial artists that do fight competitively are really good and use a combination of kicking and punching.
Sorry rambling on blah blah blah...
