Here's an interesting web site provided by Simon Earle's racing yard in the UK. He is promoting the fact that his horses are running barefoot, though the "before" photos on this site don't look too bad. What I find fascinating is the array of training/conditioning systems he has either invented or implemented to increase the soundness of the horses in his charge. He credits American K.C. LaPierre with helping him on the hoof end of things
