 So a horse is really, as far as the landing phase of how the horse travels, and Rex brought that up too, about having too long a toe where there's a delay in getting that foot off of the ground. So what happens when there is a delay, you get a toe-first landing. So when you have a toe-first landing, there is a misalignment of the distal phalanges where P2 drops back and puts load on the navicular bone.
