When I have a client wanting to transition, we work together to Prepare those hooves to meet the ground as best as we can. I want them to do exactly as you have above, except X-ray unless there’s obvious pathology (i.e., laminitis, etc):
If another round of shoing is necessary, I instruct the owner to paint the soles every single day with either Keratex or Kevlar Hoof… then, on shoe day, POLITELY ask the farrier to not carve any sole or bar out.
Then continue with the Keratex or KH until shoe pull day. In between, adjust the diet where necessary, removing as much sugar & starch as humanly possible. Also add copper/zinc if not already present in sufficient numbers. Get the horse moving more… if possible, 24/7 turnout.
Instead of buying boots right off, IF the horse is truly ouchie, we’ll cut out pieces of Garden Kneeling Pad and tape them on. This gives the owner time to measure properly for hoof boots, while providing protection until they arrive. Removed, allowed to dry out, reapply Keratex, tape on a new set if necessary.
I never ever want a horse sore, but it may happen. We plan for the best and prepare for the worst.
For boots, I have seen the best success with the Equine Fusion Jogging Shoe. Can be padded or not. Decent price point. Allows the most freedom of hoof movement, yet doesn’t rub.
