You're jumping ahead instead of actually doing the activity and thinking about it. Nothing was said about steeps or a "way to ski". Play with this stuff on flat traversing trails that are boring. There is much to be learned on those even while travelling with the herd.
"I assume you mean to roll the other foot as well, raising its little toe."

I'll have to try that. Won't be on snow for 3-1/2 weeks though
