Tendon Boots

Tendon boots are protective gear that wraps around your horse's lower leg, covering the tendons and ligaments that run down the back of the cannon bone. They're designed to protect against brushing injuries—when a horse hits their own leg—and to provide some shock absorption during landing from jumps. They're not healing devices. They're preventative protection.

Unlike many pieces of equipment, tendon boots aren't controversial. Most serious jumpers use them because they work. A horse that brushes themself going cross-country or jumping might sustain significant tendon damage. Tendon boots don't eliminate the risk completely, but they reduce it significantly. That's worth doing.

The key thing to understand is that tendon boots are athletic protective equipment. You wouldn't run a marathon without proper shoes, right? Boots are similar—they're protection for demanding physical activity. You don't need them for casual walking or light riding, but when your horse is working hard, jumping, or doing fast work, they're worthwhile.

There are different styles of tendon boots for different purposes: tall boots for jumping, shorter boots for dressage or trail work, and specialized boots for specific disciplines. Knowing what your horse needs depends on what you're doing and what your horse's legs are like. A horse with good conformation might never brush themselves, so boots are less critical. A horse that's clumsy or has conformation issues that causes interference is a candidate for every jumping session.

This article covers what tendon boots are, why you'd use them, how to fit them properly (because improper fit is worse than no boots), how to care for them, and when they're essential versus when they're optional. By the end, you'll know whether your horse needs them and how to use them properly.

Injury prevention is the entire purpose of tendon boots, and it's significant. A tendon injury is expensive to treat and potentially career-ending for a performance horse. Recovery takes months. A ligament injury is even worse. Preventative protection that might save you from a serious injury is worth the investment.

When a horse lands from a jump or pivots quickly, the tendons and ligaments are under enormous stress. If the horse also hits their own leg at that moment—something called brushing—the impact can strain or damage the tendon. A tendon boot absorbs some of that impact and protects the leg from direct contact. Over a season of jumping or galloping, that protection adds up.

Some horses are naturally prone to brushing. They might have wider bodies, or their legs are set in a way that causes interference, or they're just clumsy. For these horses, tendon boots aren't optional. They're essential protective equipment. You wouldn't put a naturally brushing horse in hard work without protection.

There's also a psychological component. Knowing your horse is protected allows you to ride more confidently. You're not constantly worried about injury. Your horse senses that confidence, and it translates to better performance. That's not trivial.

Tendon boots also provide some support and feedback. Horses don't have independent control of each tendon and ligament the way humans do. Boots provide external stability that helps with proprioception—the horse's sense of where their legs are and how they're positioned. This is especially valuable during challenging movements or when learning new skills.

Most importantly, tendon injuries are often invisible until they're serious. By the time you notice something's wrong, the damage might be significant. Prevention is far easier than treatment.

Fitting tendon boots correctly is crucial because improper fit can actually cause injury. Too tight and you're restricting circulation. Too loose and the boot shifts and provides no protection. Finding the right fit takes attention and care.

Start with your horse's legs clean and dry. You want to see the actual leg shape without swelling or mud. If your horse has filled legs from turnout or work, let them settle for a bit before fitting.

Slide the boot up the leg so it covers the tendon area—roughly from just below the knee to just above the fetlock joint. The boot should sit snugly against the leg without gaps, but you should be able to slide a finger under the straps comfortably. Use this as your standard test: if a finger fits, the fit is approximately right. If you can't slide a finger in, it's too tight. If you can fit your whole hand, it's too loose.

Fasten the straps in order, working from top to bottom or bottom to top depending on the boot design. Most tendon boots have multiple straps. Fasten each one to the same snugness—not all tight on top and loose on bottom. Consistency matters for support.

Once the boot is on, flex the horse's leg. The boot should move with the leg, not pinch or bind. Watch for any red marks or swelling once you remove the boot. If you see pressure marks or swelling that doesn't go away within a couple of hours, the fit is wrong.

Different horses have different leg shapes. A horse with thin, refined legs might need smaller or narrower boots than a horse with thicker legs. One brand might fit your horse while another doesn't. This isn't one-size-fits-all equipment. You might need to try a few pairs before finding the right fit.

When applying boots, do it before you ride while your horse is calm. Don't try to apply boots to an anxious or moving horse. Make it part of your routine—saddle up, then apply boots, then mount. Most horses accept them once they're used to the routine.

The boots themselves are your primary tool, and there are many options available. Tall tendon boots designed for jumping are common. They extend higher on the leg for more protection and are usually adjustable so they fit different leg shapes. These are typically what people use for schooling jumpers.

Shorter tendon boots, sometimes called brushing boots, provide protection for the tendon area but with less height. These work well for trail riding, dressage, or other activities where you want protection but less restrictive coverage.

Material varies. Synthetic boots dry quickly and are easy to clean, which is why many riders prefer them. Leather boots are classic and traditional, providing a tailored fit and elegant appearance, but they require more care.

Neoprene or padded tendon boots offer more shock absorption, which some horses appreciate and others find restrictive. Trial and error is part of finding what your horse likes and what works for your discipline.

For applying boots, you need nothing special except clean hands and a calm horse. Some people use baby powder or similar to help boots slide on more easily, especially if they're fitted snugly. That's optional but can help.

For cleaning, use mild soap and water after riding. Dry thoroughly before storing to prevent mold and deterioration. Some people use a boot brush to clean dried mud before washing, which saves time. Hang boots to dry rather than leaving them in a damp heap.

For storage, keep boots in a cool, dry place. Don't store wet boots or they'll mildew and deteriorate. If you use them regularly, they'll develop dirt and stains—that's normal. Function matters more than perfect appearance.

Consider having two pairs if you ride regularly and don't have time to dry and maintain boots constantly. Rotating between pairs extends the life of each pair.

Use tendon boots whenever you're doing work that stresses the tendons and ligaments. That includes jumping, galloping, fast work, pivot turns, or any high-impact activity. For casual walking or light riding on flat ground, boots are optional unless your horse has a specific issue like brushing.

Don't use boots for turnout or casual movement. Boots are athletic gear for work, not daily wear. Using them constantly can actually create problems because the leg adapts to external support. When you take the boots off, unsupported tendons are more vulnerable. Use boots during work, then let the leg work without support during rest periods.

Timing on the day matters too. Apply boots just before work, ride with them on, then remove them immediately after work. Don't keep boots on longer than necessary. Removing them right away lets you check for any irritation or swelling and allows proper circulation recovery.

For horses that just started wearing boots, introduce them gradually. Wear them for a short ride, then remove and inspect. If everything looks good, increase duration and intensity. Some horses need a couple of sessions to get used to the feel and stop being distracted by them.

During the off-season or during downtime, your horse doesn't need boots if they're not doing demanding work. Use them when activity ramps up or when you're asking more of the horse physically.

If your horse has a specific issue—recovered from an injury, prone to brushing, or has tendon sensitivity—you might use boots more frequently. This is where listening to your vet and your veterinarian's advice makes sense. A friend would recommend asking your vet about boot recommendations for any specific leg issues.

Pro tip: if your horse fills easily or has swollen legs after work, remove boots immediately after riding. Don't leave them on while the leg is warm and swollen. Let circulation recover and swelling reduce before assessing how the fit is. This prevents pressure marks from looking worse than they are.

Another pro tip: buy boots that match your horse's actual leg, not the size the horse "should be" based on height or weight. A small-boned Thoroughbred needs different-sized boots than a stocky Quarter Horse. Measure your horse's leg and try boots on before buying if possible.

Common mistake: buying boots that are too tight because you think tight means better protection. Overly tight boots restrict circulation and actually increase injury risk. They can cause swelling, lameness, and tendon problems. Snug and supportive is good. Tight and restrictive is bad.

Another common mistake: not cleaning and maintaining boots properly. Mud and sweat left on boots can cause skin irritation. After every ride, rinse off major dirt and let boots dry. Once a week or after muddy rides, give them a thorough cleaning. Boots that are cared for last years. Neglected boots deteriorate quickly.

If your horse develops swelling or lameness that seems related to boots, stop wearing them immediately and call your vet. It's possible the fit is wrong, or the boots are causing an issue. Don't keep using equipment that's causing problems.

If your horse constantly refuses to cooperate when you try to apply boots, you might have a fit issue. A boot that fits correctly and is applied calmly is usually accepted. If resistance continues, try a different style or brand that might fit better.

For horses with very sensitive legs or previous injuries, consider neoprene or padded boots that provide more cushioning and support. The extra padding can make a difference in comfort for these horses.

Remember that boots are protection, not treatment. If your horse has an actual tendon issue, boots might help prevent worsening, but they won't heal an existing injury. For health concerns, call your vet. Boots are preventative equipment for sound horses doing demanding work.
