The first thing that jumped out at me was the wide stance. But for bowlegged skiers this is a good adaptation. Alas, you already know what the first piece of advice is: get new boots and get your orthotics adjusted so that you can stand neutral on your skis without your feet being > shoulder width apart 1/2 the time.
Here's what I see: Some of your turns are parallel and some are wedge christies. You start your left turns with a little shoulder movement. You turn your feet to change direction then set the edge to slow down. You have a tiny bit of leg flex at the end of the turn and tiny bit of extend going into the new turn.
Here's what I want to see: All your turns are parallel. Let the skis turn you instead of you turning the skis. Control speed more with turn shape than with skidding against the edge. Learn to "go" instead of "slow".
Here's how we're going to do it:
Get the boots fixed
Narrow the stance from outside shoulder width to shoulder width
Do the tug of war drill
Do the fan traverse drill
Learn the movements for making these kinds of turns with big turns first, then go back to making the shorter turns that you are comfortable with.
There are many different roads you can take to higher performance skiing. You can pick and choose what you like from the different advise you're likely to get or you can find a coach you can work with on a regular basis. If you ski in the Catskills, I recommend a visit to Ron White.
Tug of War
You need a partner. Stand with your skis sideways across the hill with your partner directly below you. Take your poles off. Hold two poles together with both your hands at one end and have your partner hold the other ends (most experienced person holds the pointy ends facing them). Experiment with how much force it takes to pull you down the hill. Vary your stance width, the direction your shoulders and hips face, the height of your butt off the snow and the edge angle of the skis. You'll find that you have the most resistance with the hips and shoulders facing down the hill, the butt low to the snow and the edges on high angle. This is the position you want to get in doing the largest turns on the fan traverse.
Traverse across the hill at a shallow angle. Beware of crossing downhill traffic. As you pick up speed, tip your boots and knees into the hill. The skis should track uphill until you stop. Check your tracks. If they are not thin lines, you turned your feet. Start on a shallower traverser. Gradually increase the starting angle making one turn/traverse to an uphill stop. Keep increasing until you are starting straight downhill and still leaving thin tracks in the snow. Remember to get into the tug of war position as your speed increases. Notice how effortless it is to slow to a stop by going uphill.
Thank you. I will get new boots but am of the philosophical bent that its not the equipment but the player who is primarily responsible. Now that I have improved sufficiently - will focus on getting new boots. Also will work on their alignment to straighten out my stance and make sure canting is set farther forward.
Will try the exercises as you listed and also the angulation 'angle' feel, at higher speeds it seems to come more naturally. Will work on it. Once again I appreciate the systematic breakdown. That "swish" of my left ski when I am turning right which makes it a wedge-christiesh turn, I feel my left leg just not setting down hard enough as I transition to make it the downhill ski. Just something I presume will come with practice. As opposed to that, the left turn, where I transition to right ski as downhill ski, seems to flow much better. Not sure why, but potential guesses are (a) me, the skiier (b) being a righty-not yet got total confidence in weighting down with ankle flex on left leg (c) the boots could make all the difference.
Thanks for the step-by-step counsel
It is possible to ski with ill fitting boots. It's a lot harder to learn with ill fitting boots. Why are there no child clowns? Because we teach them to walk with regular shoes on first before we strap them into clown feet. When you try tipping your skis on edge to turn, it is harder to balance. If your feet are slopping around fore and aft inside the boot AND you are not aligned left/right either, then it's going to be really hard to balance. Stuffing helps, but not enough.
It's not a matter of only fixing the right turn. I want to make fundamental changes to both turns. But until you get your boots fixed, you're better off turning the way you are. I tried hammering a nail with my shoe once. A smart man observed me placing the toe of my shoe over the nail and me beating on top of the shoe and suggested I try swinging the heel at the nail instead. A wise man gave me a hammer. We could make changes to your skiing now, but it would be like learning to do carpentry with a shoe instead of a hammer.
