Double Ditto what Boosiler said.
I've been riding Walking horses for 17 years. I don't do anything but trail ride and parades.
No long toes, no high heels. No weighted shoes.
I don't even use the traditional keg shoe on any of my Walkers.
I use St. Croix rim shoes for grip
Toes "Quarter Horse" short, angles natural.
Everyone does their inherent gait and does it well (smooth).
I also ride these same Walkers barefoot in the winter time. They gait the same barefoot as with shoes on, but I don't ask them to "walk on" if we are on a gravel road or the blacktop.
If trail riding is the goal for now, a normal trim by any qualified blacksmith is what is needed
