Hey. Just wanted to clarify. When we walk down the street our aim is to travel a distance. That is why we usually step forward with our heel. It produces a natural "rolling through the foot" movement. It is also why we are told to release our toe as we move back. Try it. Move forward using your toes and feel the "chicken walk" stunted effect. Then use your heels and feel the gliding difference. Toes are used in the latin dances to improve the grounded feel of the dance. Toes are like glue and they check your actions so you can commit your full weight to a foot and stay in one place. Hope this helps :)
