Wallee, there is video floating around somewhere where veterinary medical professionals take x-rays of a big lick walking horse's foot. If you haven't seen it, you should.
I'm not saying they all sore their horses, but the enormous padded shoes are harmful enough. I'll take less flashy movement over an unsound animal any day.
As I stated before, walkers in their natural state of movement are just gorgeous... they don't need gadgets and questionable methods to make them beautiful.
Most Big Lick horses move like they have muscular disorders.
