Sign to end the practice of horse soring

[Catherine]

Soring is a practice of damaging a horse's legs and feet so that the horse will  pick up its feet in an exaggerated gait. It is cruel and painful and needs to be stopped.

I can't imagine how this practice started or why it persists. It seems bizarre to even think of deliberately hurting a horse. 
Why do they even want the horses to walk like that.
