Thanks. Without actualy owning one, it is hard to know. It is good to have piece of information - knowing that you have selectable tread/traction.

I wonder if a 4 wheeled omni type robot could be made with only the slippery grey wheels. Would they have enough slip to allow holonomic movement?

No.
Omni-wheels only work in a holonomic application if they have rolling traction, but not lateral traction.
These wheels have no traction in either direction.
