This is one of the more difficult, esoteric stances in Shotokan Karate. It is not so deeply rooted, yet capable of delivering great power and balance when used in good form.
Hangetsu Dachi is similar in length to the Zenkutsu Dachi. Also similarly, the feet are about shoulder width apart. In the Hangetsu Dachi, the front foot is turned inward to approximately a 45 degree angle. The rear foot is turned out to approximately a 15 to 20 degree angle. The front knee is pressed to a point inside the ball of the front foot if viewed from the top. The rear knee also is pressed to the inside of the rear foot, making a very closed-leg stance, almost as if one were trying to carry something using the knees.
The hips are pressed forward and rotated upwards, and held at approximately a 45 degree angle. The weight is distributed with slightly more weight forward than rearward, about 60/40. The back and head are straight, the shoulders are aligned with the hips, and the abs are slightly tensed.
