Actually, I believe that it can be elastic, if the friction is so great that the surfaces do not slip the entire time they are in contact.

Yes. They can bounce back and forth due to the spin reversing. I believe each time they make contact with the floor, high friction causes of spent to stop, while they undergo a rotational deformation, which then reverses direction.
