Balance is easily maintained in this maneuver if the raised free foot is pulled in close to the stance foot. A wide stance with feet apart will eliminate the turn control of the free foot. A wide stance moves the center of balance too far into the slope, compromising balancing and carving.

Notice how pressing the free foot toward the stance foot has produced symmetry in leg angles to the snow. The muscles contracting to produce these positions and actions result in a powerful position of balance.

By keeping the free foot close to the stance foot in transition, both side-to-side and fore/aft balance on the stance foot is improved.
