How do you walk?
When I walk around my house, other peoples house, etc, I tend to step with the ball of my foot, to avoid the "stomp" of the heal-toe action. When I'm at work walking around the shop floor I just do heal-toe because it is a bit sturdier of a walk.
The reason I wonder is because the person in the room above me is very heavy footed. And for some reason they seem to walk around for 2-3 hours every night. *Stomp Stomp Stomp Stomp*. Clearly a Heal-Toe walker.
