Ask the vet to see the lateral(side view) X rays. Look at the angle of *bottom edge* of the coffin bone, in relation to the ground. Is it parallel, or tipped down in the back? Or is it tipped five or six degrees up in the back? That is the best guage for changing the hoof angles. The angle of the bottom edge(solar surface) of the coffin bone should usually be seven or eight degrees higher in the rear as compared to the ground. Also make sure whatever type shoe you use to get the breakover at no more than an inch and a half in front of the tip of the frog. Any farther than that will increase the pull on both the tendon and the ligament that runs around the navicular bone to the bottom of the coffin bone, That tension is usually the biggest factor that started the navicular problems in the first place.Alkso make sure the heels are trimmed nback if they are tall and run under, do not use the hoof ewwall at the heels to try to raise the angles, use the shoeing instead. If you leave the heels tall to raise the angles, the wall there just runs forward, adding more pressure in the heel area as the support goes too far forward.
If there are no lateral X rays to see, trim the foot, including the heels if they are long, and then use however much wedge it takes to get the foot and pastern to line up.it is not nearly as accurate as using the Xrays, but not bad.Just get those heels and the breakover back under the foot.Patty
