Some mis information is being cast about here.
My Head WC boots of more than 20 years experience are as useful today as they were when first new. I ski every day, with no issue.
The latest is not indication of better.
Trying the suggestions of a pro instructor might help, but then they might not. With the background of the OP, it may be better to experiment on ones own.
In skiing, there is no substitute for mileage!
