heel strikers

Simon: I've been reading the banter between you and Bobby about 'heel striking' and I can't tell if there's some arrogance from some runners about heel runners, or you're just having fun bashing each other..

But here's a serious question from someone who definitely doesn't have perfect form. What can I do to improve my form so that I'm properly landing on the balls of my feet - and thus be a candidate for a pair of those garish colored Newtons?

And do I have to learn to run like that to be a successful runner? (Would Bobby be faster if adapted and learned to love the Newtons?)
