Foot maneuvers are basically the movement between stances. The improper execution of foot maneuvers can introduce a number of complexities of not only the movement itself, but also affect the new stance that is obtained at the end of the foot maneuver. The section on stance correction gives further highlights into this information.
There are a number of common errors exhibited while executing foot maneuvers. Bobbing is one of the most common problems demonstrated by many beginning practitioners. Transitions between stances should be fluid while also maintaining the same height level. Once Long Form One is started, the practitioner's head should remain at the same level throughout the entire execution of the form (including the Meditating Horse).
Another common general error is extra motions, i.e. breaking the principle of Economy of Motion. This problem is exhibited in many forms, the most common of which are: moving the feet prior to actually executing the foot maneuver (extremely common), breaking the heel (lifting the heel) during step through maneuvers, pivoting on the heel of the foot, and/or Jet Lagging (leaning while stepping through).
