The term True Hard Sole Plane is a scam. Please do not fall for the trap on compaction. It is a complete fraud on natural hoof care.
The actual compaction takes place when solar plates, when prodded with the nipper, begin to loosen up, like a loose tile. Not quite ready to fall away on its own, but there's a little crack and minimal movement.
Solar plates often become compacted because of prolonged periods of drought and not enough access to moisture, like a water hole or wet ground. In Paddock Paradise, we'd create a water hole or something like a shallow pool to encourage horses to soak their feet from time to time.
An important point needs to be added to the overall water/moisture hoof situation. In environments like the UK, where winters can see excessive amounts of water, especially now with more extreme weather events, it is important to create a dry area where neither horses nor hay get soaking wet. An area where their feet don't need to be in mud. Mud damages hooves.
Moisture helps to soften the solar plates and remove the material, so their sole is much more likely to be at the Hard Sole Plane, providing there's healthy ground stimulation.
On the other hand, lack of moisture leads to the individual, thin layers of solar plates to laminate into chunkier-looking solar plates sticking together and hardening up. Those chunks can be pretty thick, even over 1 cm in thickness. Solar plates are not of uniform thickness, their shape is never linear, and they can be irregular. Nevertheless once you see how solar plates look like, you'll always be able to tell the difference.
Compaction, contrary to some of the claims, is not painful. What is painful, on the other hand, is excessive removal of epidermal structures (hoof armour), be it around the seat of corn, heel buttress or around the toe in excess to their natural thickness.
Sensitivity and soreness are not always born out of inflammation. Think of the hoof capsule as a container. If you thin the wall of a container too much, what will happen? It begins to lose its integrity. It begins to falter.
Please don't let anyone tell you otherwise: that the true hard sole plane is found with the flat rasp and heels taken down to almost nothing. Coronary corium at the back of the foot grows full wall thickness 1cm below the coronary band. There isn't always much mass to work with. Taking heels down too far is not safe. Compaction is not what is claiming. It is a scam. Under the guise of compaction plates not ready to shed are being removed, compromising the heels exposing Live Sole Plane.
Heels take an enormous amount of weight. Reducing mass by force in the most important places, designed for active wear, has detrimental long-term consequences. If you witness long heels, perhaps after a prolonged period of shoeing, you have to give them time. According to studies conducted by Jaime Jackson, supercorium needs about 2,5 hoof growth cycles (hgc) to remodel. That is about 2 years. Those changes should never be rapid and drastic.
Over-trimming the heels doesn't necessarily have to create negative palmar angles, but it will invariably weaken the supercorium's ability to produce a sufficient amount of mass over time. What is gained in the short term is lost in the long run.
Horses with thin soles and heels that don't seem to grow are an example of excessive hoof mass removal. Human nail biting is a great analogy. When nail biting is done systematically, it leads to a shorter nail plaque over time. But horses need their heels more than humans proportionate nail plaque. They depend on healthy and sound feet for survival.
Biologically speaking, the hoof is a living organ that responds to its environment.
PS. Photos showing an example of compacted solar plates. When scraped from the top, they remain firmly in place. When prodded with the nipper, they lose up and lift.
