Typically applied as a spin kick. Stand in left foot foward fighting stance (sanchin, cat-foot, or equal weighted). Rotate body clockwise, dropping weight onto front leg as you turn back to opponent. Head should turn as well. Kick is launched when you can just see opponent out of the corner of eye. If you can see with full eye or both, you will end up with a side kick (over-rotation).
Hip/back point to target. Lift knee. Extend kick in a thrust to/through target (6″). Foot points toward floor at impact and throughout. Point of contact is bottom of heel. Pull kick back as you turn to face opponent and set down for another technique.
Reverse for both sides. Practice both sides equally.
