You could put hoof boots on for loading to help with the sliding
issue. Because you are not actively riding in the boots you have a lot of choices!
I agree with the
previous post to correct the hoof issues with a natural trimmer. It may take
several trims to get the problem corrected, but well worth the effort. Good
luck!
