I think these pictures beautifully illustrate what actually lies underneath the hoof wall. It is my opinion that when we see changes in/on the outside of the hoof wall, they are directly related to what is going on inside of the joint capsule.
We can all agree that horseshoes do a great job protecting the hoof wall - what our pad does is compliment the shoe and enhance the function. It cushions the hoof where it impacts the ground -- this reduces the concussion which subsequently reduces inflammation and pain. The hybrid combination of our pad with your choice of shoe will protect the sensitive structures inside the foot while still allowing the hoof to function as Mother Nature has intended.
