1) I've found the best ways to keep the hips over the feet is to pull the feet back under the hips. Flexing the ankles means pulling the feet back, anyway, those are the words that work for me.
2) The best forward lean of the boots varies for different individuals. Some folks ski better with boots with more forward lean. Other folks with different skeletal geometry find that more forward lean hinders their skiing. More is not always better. "...something the racers spend a lot of time figuring out is the amount of angle they need on their ski and in their boots...."
3) Flexing the knees into the turn doesn't work with the arthritis in my knees. What works better for me is to press the outside foot ankle into the side of the boot for more ski angle on the snow. I keep my knees flexed but straight laterally. Doesn't bending the flexed knees sideways pre-load the ligaments and they'll tear more easily if something is hit?
4) Many skiers always have their inside foot farther forward than Bode is showing. For many of us, pulling the inside foot back, way back, results in the foot in the right position and the feet under the hips for proper fore/aft weight distribution. Pulling the inside foot back while pushing the inside hip and shoulder & arm forward sounds contradictory, but works very well for most. The body will be properly countered (counter facing) and in balance.
5) Note how close together Bode's knees are. No room for a basketball there. His feet are vertically separated to make room for the angulation, and sometimes a bit apart on the transition between turns, but not forced apart in the turn. Also, not a word about steering the ski. Just put the ski on edge and let it turn you.
6) For counter balancing...dropping the outside shoulder & hip...a gizmo that is a real help is Chris Braisby's The SKI COACH
. I trust few gadgets, but this one works as described to help folks learn counter balancing.
Bode Miller is not a good technical skier. He's won some exciting World Cup races because of his guts and athleticism. For better technical skiing, and often better results, look at Benni Raich and Georgio Rocca. Among the women, look at Nicole Hosp and Marlies Schild. Niki Hosp especially shows the still upper body and head in the recent Levi, Finland, WC slalom race. Austrian Sport1.at has videos of the WC races. I think the slalom races best show form that recreational skiers can use. In the Sportskool vid, Bode was making GS turns, but not at GS speeds. GS can be up to 40 mph these days, and the skiers need form to handle forces that don't apply to most of us. All recreational skiers can ski better using the fundamentals the racers are using.http://video.sport1.at/index.php?view=1906
