Which foot should be my leading foot?

A skateboard has angled parts at both the front and back in the direction of travel, and the back part is called the tail. As explained in another Tip (Link), both tic-tacs for changing direction and the ollie, which is a basic trick, begin when you press the tail down with your back foot. That means if you want to transfer force to the tail more efficiently, it is better to place your dominant foot on the tail. When you push, you also kick the ground with your back foot, so by the same logic, it makes sense to place your dominant foot in the back so you can push the ground more powerfully. By the way, a stance with the left foot in front is called regular, and a stance with the right foot in front is called goofy.
