Motion is lotion…
So if a horse starts struggling the more work or turnout they get, this is the very first place I recommend owners look…
No foot, no horse.
Or maybe… no heels, no horse.
Excessive heel trimming has been popular off and on in both the barefoot trimming and farrier world since I started trimming 25 years ago, and long before.
It’s something I’m constantly having to rehab, that has a huge impact on the whole horse… from hind end issues, to lack of engagement or suspension in the gaits, to horses being ‘footy’ on difficult terrain due to the lack of vertical depth in the foot, to body-wide dysfunction and discomfort, and an overall decline in performance.
It can be pretty insidious, because some horses have a narrower window for error than others when it comes to the equilibrium between their flexor and extensor systems.
As well, if heels start out low, and a practitioner doesn’t put effort into correcting them, the heels may not necessarily be getting trimmed too low, they just aren’t growing at all, due to overload in the back of the foot, so the practitioner may mistakenly believe they are setting the heels at the appropriate height, since they’re at the sole plane.
This is one area in particular where I see desperate owners pouring a huge amount of money and energy into symptoms, without ever getting to the origin of the problem.
We can’t bodywork or chiropractor or train our way out of this problem, because those things can’t compensate for an ongoing mechanical problem in the foot.
A lot of these horses will go years being ‘not quite right’ before they start to break down and show obvious symptoms.
The tell-tale red flag is the broken-back HPA, Hoof Pastern Angle.
This is often exacerbated, like we see in the first few pictures, due to the horse being reluctant to load into the fetlock and the back of the foot.
I believe the rehab horse below was one misstep up away from a tendon or ligament injury…
If there’s one thing I could encourage everyone to educate themselves about, it would be how to observe HPA and be on the lookout for a broken-back HPA.
It’s simple enough owners can keep an eye on it without needing a ton of technical knowledge or experience.
The Equine Documentalist has some of the best educational content on this out there, including references to the science of the toll BBHPA has on the tendons and navicular area.

I feel like I’m seeing an uptick in this style of trimming again. It’s normalized in certain camps, but eventually, many of these horses begin to show declining comfort or performance and a need for increased intervention.
It’s so incredibly important that we listen to the science, listen to the horses, and not our own egos or beloved gurus.
I attribute prioritizing HPA as the main reason my own horses have stayed sound over the years.
I also think it’s a big reason why they don’t require boots or shoes or a lot of interventions like bodywork, etc.
Nowadays, there’s really no excuse for those of us trimming or rehabbing to not be educated about this, and we need to be educating owners.
Another great article…

Adequate vertical depth in the back of the foot goes beyond simple heel height.
