I'm new in this site came across this thread because i was looking for off season training like skiing .
Well ski technique is quite simple :
1 move your weight to the opposite direction out turning ski .
2 lean into the turning center.
3 follow with your vision to center off the turn circle
if you like to teach a beginer or simulate it you'll need some skate to simulate it
Those nordic skate like : skike power slide coyote you name it ain't doing this job even though seem to be great fun..
this inventions seem to be the right one ..
