Chusoku
The Chusoku is the ball of your foot. To correctly use this in a kick you flex the foot forward at the ankle and pull the toes back so that you strike with the ball of the foot. |
Commonly this is used in Chusoku Mae Geri and Chusoku Mae Keagi, however this portion of the foot is used a lot when transitioning from one stance to another, when turning and even in some stances such as Kake Dachi. |
