Top 2 pics, are an example of what farriers do, to upright a heel. They back the heel to the widest part of the frog. They attached a wedge and shoe to build a false heel. This does not even make common sense. They remove the heel to rebuild the heel!
Not only have they removed sole depth, the heel, and flattened the digital cusion, they caused severe stress to the tendons and ligaments. They did not heel the distortion and mechanical lamenss. They put a band-aid on a huge issue. Gadgets and gimmicks don’t heal the hoof and get to the root of the problem.
You ask why people do what they do? They don’t know better. Do not let trimmers that don’t know better try to fix the mistakes they caused. They will ruin your horse! You endup with worse mistakes and a rabbit hole of lameness and ruinded horses. The ligament and tendons on this horse won’t hold up forever with this mechanical stress. Not to mention the joints with the metak shoe and lack of sole depth. The destruction of the lamina health.
Second set of pics is a rehab by Apex out of the farrier trim. A farrier would of wedged this hoof and never uprighted the heel. We actually uprighted the heels, rebuild the digital cusion and bone alignment. The enire hoof and horse is rehabbed. I do this all day every day. Correcting bad trims and actually healing the disortions in the hooves.
