heal-toe is exactly what it sounds like. what you do is basically bounce your leg up and down making it so that your heal hits the peddle, then on your way up you tap your toe so that it hits the peddle. it should create a rocking motion.

one tip is that it is heal, heal, toe , toe.

you can also check out some videos on youtube or something like that.
