Shoeing a horse with ringbone focuses on reducing joint stress, easing breakover, and minimizing concussion with every stride. Because ringbone is a degenerative condition involving bony growths around the pastern or coffin joint, the shoeing approach isn’t a one-time fix. It’s an ongoing management strategy that works best when a farrier and veterinarian collaborate on a plan tailored to the specific joint involved and the severity of the disease.
How Ringbone Affects the Foot
Ringbone produces extra bone growth around the joints in the lower leg. High ringbone affects the pastern joint, while low ringbone affects the coffin joint deeper inside the hoof. This distinction matters for shoeing because the two joints move very differently. The pastern joint is naturally a low-motion joint, which means horses with high ringbone sometimes remain rideable, especially if the joint eventually fuses. The coffin joint has much more movement, making low ringbone harder to manage and more likely to cause persistent lameness.
Ringbone can also be classified as articular (involving the joint surface itself) or non-articular (bone growth around the joint but not directly on the cartilage). Articular ringbone tends to cause more pain because it disrupts the smooth gliding surfaces inside the joint. X-rays are essential before any shoeing decisions are made, because they reveal which joint is affected, how much bone has changed, and whether the joint is beginning to fuse on its own.
The Trim Comes First
Good shoeing for ringbone starts with the trim. The primary goal is establishing a correct hoof-pastern axis: a straight, continuous line from the front of the pastern down through the front of the hoof wall when viewed from the side. When this alignment is correct, the coffin joint, pastern joint, and fetlock share load in a coordinated way, and no single structure absorbs more force than it should. A broken-back axis, where the hoof angle is too low relative to the pastern, is especially problematic because it increases strain on already damaged joints.
Correcting alignment requires reducing excess toe length, improving heel support, and making incremental changes rather than dramatic ones. Each horse’s conformation is different, so the goal isn’t forcing the foot into a textbook angle. It’s optimizing load distribution within the limits of that individual horse’s structure. Aggressive corrections in a single trim cycle can make things worse by suddenly shifting forces to tissues that aren’t prepared for them.
Easing Breakover
Breakover is the moment the heel lifts off the ground and the horse rolls forward over the toe to begin a new stride. In a healthy horse this happens smoothly, but in a horse with ringbone, the leverage required to rotate over a long toe creates painful stress on inflamed joints. Reducing that effort is the single most important mechanical goal when shoeing for ringbone.
Several shoe modifications accomplish this. A rolled toe has the front edge of the shoe beveled upward, shortening the distance the hoof has to travel before it leaves the ground. A rocker toe takes this further with a more pronounced curve. Setting the shoe slightly back from the toe of the hoof achieves a similar effect by moving the breakover point closer to the center of the foot. Square-toed shoes, which flatten the front of the shoe rather than following the hoof’s natural round shape, also reduce the lever arm at the toe.
A full rocker motion shoe goes beyond these options. It has a convex ground surface, meaning the entire bottom of the shoe is curved. This allows the foot to rock in multiple directions, offering what’s called a self-adjusting palmar angle. Unlike flat shoes with modified toes, a rocker shoe continues to offer mechanical benefit even when the horse is standing still. Standard breakover modifications like rolled toes and set-back shoes help when the horse is moving but don’t provide the same self-correcting alignment at rest. For horses with significant joint involvement, the full rocker design can make a noticeable difference in comfort.
Choosing Shoe Material
Steel is the traditional choice for horseshoes, but aluminum and synthetic materials offer real advantages for arthritic horses. Aluminum dissipates vibration far more effectively than steel. Its damping coefficient is roughly 100 times higher, which translates directly to less concussion traveling up through the joints with every step. This reduces the microtrauma that accumulates over time and worsens degenerative joint disease. Aluminum shoes are also lighter, which decreases the effort required to move the limb.
Synthetic shoes, made from polyurethane or similar materials, offer another option with good shock absorption. Pads placed between the shoe and the hoof can also dampen vibratory forces. Some farriers combine approaches, using an aluminum or steel shoe with a pad and packing material underneath to maximize cushioning. The tradeoff with lighter materials is durability: aluminum wears faster than steel, which can affect shoeing intervals.
How Shoeing Works With Veterinary Treatment
Therapeutic shoeing is one piece of a broader management plan. Veterinarians often treat ringbone with joint injections to reduce inflammation inside the affected joint. Corticosteroids are the most common first-line option. When a horse doesn’t respond to steroids, biologic therapies offer alternatives. IRAP (interleukin-1 receptor antagonist protein) blocks one of the body’s key inflammatory signals and has shown benefit in arthritic joints that are refractory to steroid treatment. Stem cells and platelet-rich plasma (PRP) are other options, generally used earlier in the disease process when the goal is to slow cartilage breakdown and reduce inflammation.
The farrier’s work and the vet’s work reinforce each other. Corrective shoeing reduces the mechanical forces that aggravate the joint, while injections address the biochemical inflammation happening inside it. Neither approach alone is as effective as the combination. This is why the recommended approach is a team effort between owner, veterinarian, and farrier, with X-rays guiding everyone’s decisions.
Maintaining the Shoeing Schedule
Horses with ringbone need consistent farriery intervals. As the hoof grows, the carefully established breakover point migrates forward, the hoof-pastern axis changes, and the mechanical benefits of the shoeing package gradually deteriorate. Research on working horses found that intervals beyond six weeks allow excess loading on the structures within the hoof, increasing long-term injury risks through cumulative stress. For a horse already dealing with joint disease, this matters even more.
A four to six week cycle is the general recommendation, but the ideal interval depends on the individual horse’s rate of hoof growth, the shoe material (aluminum wears faster), and how much the horse is working. Horses on softer footing or lighter work may hold their balance a bit longer, while horses working on harder surfaces may need attention sooner. The farrier should evaluate hoof balance at each visit and adjust the trim and shoe placement as the condition progresses.
What to Expect Long Term
Ringbone is a progressive condition. Shoeing can significantly improve comfort and extend a horse’s working life, but it doesn’t reverse the bony changes that have already occurred. The long-term outlook depends heavily on which joint is involved. Horses with high ringbone (pastern joint) often do well because that joint naturally has limited motion, and if it fuses, either on its own or through surgical intervention, the horse can return to work with surprisingly little lameness. Fusion of the coffin joint is a much more difficult outcome because of how much movement that joint normally provides.
For horses where the goal is comfortable pasture soundness rather than return to work, therapeutic shoeing still plays an important role. Reducing concussion and maintaining proper alignment keeps the horse more comfortable during daily movement. As the disease progresses, the shoeing approach may need to evolve. What works in the early stages, when inflammation is the main problem, may need modification as bony changes advance and joint motion decreases. Regular X-rays help the team track those changes and adjust the plan accordingly.
Preventing rapid progression is also worth considering. Avoiding heavy or constant work on hard surfaces reduces the repetitive impact that accelerates joint damage. Maintaining good hoof balance throughout the horse’s life, even before ringbone develops, helps minimize the structural stresses that contribute to the condition in the first place.
