Tipping the new inside foot to the little toe edge rotates the foot so that the toes point inward. So tipping that foot, at the ankle, to the LTE, points the toes of that foot in the opposite direction of the new turn.
This is not a problem. It's an opportunity.
Yes, you are not effectively tipping your inside foot to the little toe edge. To tip that foot to the LTE more effectively, you can take advantage of this information about the toe-pointing.
Point your new inside foot's toes in the opposite direction of the new turn, to the inside of the new turn, as you tip that foot.
So in a turn to the right, the new inside toes should be pointing to the left? To the outside of the turn rather than to the inside of the turn as written?
This sounds counter-intuitive, and it is, but it works. The toe pointing exaggerates/enhances to tipping.
If on the other hand you are attempting to get that foot tipped to the LTE and at the same time rotating the foot to point in the direction of the new turn, the rotation will cancel out the tipping, or at least reduce it.
As you point the new inside foot's toes to the inside (
Inside of the turn or the inside of the body?) and tip to the LTE, roll that knee outward and down, towards the snow. You don't want to be rolling the new inside knee inward towards the other knee. That will delete any good tipping that you are doing at the level of the foot.
In the post above, you speak of "a tension of opposing rotations." It sounds like you have that tension backwards. Try doing it this way: rotate foot in, rotate femur out. This will get that foot tipped, keep it close to the other foot, and eliminate that A-frame.
The sensation you will be chasing is going bowlegged while inviting a sprained ankle.
