The Parelli saddle does NOT claim to improve CONFORMATION. Conformation is skeletal and can not be changed. However, the saddle will help the horse's POSTURE. Conformation and posture are two completely different things. The saddle is legit as far as I'm concerned, I've had the priviledge to ride in it and my horse moved so much freer and it really improved everything overall. But lets not get into a debate about the saddle, shall we?
