This thread is for seasoned instructors who teach adults a wedge for their very first straight runs and very first turns to the right and left.
(This is not a thread about whether the wedge is a good way to teach beginners or not; please do not post if you want to argue about that.)
You must run into adult students sometimes who simply cannot hold the wedge.
They can't keep their ski tips pointed inward when doing a straight run on extremely low pitch terrain.
Or they can for a very short distance, but they are very ineffective in getting those two skis tipped to even a tiny edge.
When they try to tip the wedged skis to big toe edges, the skis go parallel or wobble in all directions and the wedge is lost.
If they keep them pointed in a wedge, they have no control over whether they are on the big toes edges or flat, or whether they are balanced equally on both skis or not.
The skis wobble from parallel from wedge to diverging tips, completely out of control.
1. Do you have ideas about WHY this happens? Boots sloppy big? Skis exceedingly wide underfoot? Lack of foot/leg proprioception? Lack of foot/leg strength? Fear shutting down the mind's control over feet and legs?
2. What do you do? Do you ever send them back to the rental shop?
3. How long does it take for you to get them to a successful first straight run in a wedge? Is your beginner lesson long enough for you to get these wobbly skiers successfully to their first wedge turns? How long does it often take?
