The Angle Guage
The angle gauge has to be held tight to the foot .
We don't want to walk with two different heights of heels on our shoes. Also the horse has 7 joints between his coffin bone and his elbow. Being two different angles can put stress on their joints.
I like to check angles on both fronts to see if there is any difference before I start. This gives me an idea if I should take off toe or heel.
