Why Leg Protection Matters
A horse's lower legs are among the most vulnerable structures in its entire body. The tendons, ligaments, and splint bones below the knee and hock are close to the surface, minimally padded by muscle, and exposed to impact from the horse's own hooves, arena surfaces, fence rails, and other obstacles during work. A single strike injury to the splint bone or a knock on an already-inflamed tendon can sideline a horse for weeks to months. Leg boots are the most practical, affordable line of defense against this kind of damage.
That said, no boot is a substitute for correct training, good footing, and appropriate work levels. Boots protect against accidental impact — they do not make poor technique or overwork safe. Use them as part of a complete leg-management program, not as a license to work harder or on worse footing.
Types of Protective Boots
Splint Boots (Brushing Boots)
The most commonly used boot in western performance, barrel racing, and general training. Splint boots wrap the cannon bone and protect the medial splint bone (the small bone on the inside of the cannon) from being struck by the opposite hoof — a "brushing" injury that is common in horses with conformational faults or when working in tight, quick patterns. They are applied to the front legs (and sometimes hinds) with hook-and-loop or buckle closures and should sit firm enough to stay in place but not so tight as to restrict circulation or movement. The impact-resistant padding should sit directly over the splint bone.
Bell Boots / Overreach Boots
Bell boots encircle the hoof and protect the heel bulbs and the coronary band from being struck by the toe of the hind hoof — "overreaching" — which happens when a horse's hind foot swings further forward than the front foot and lands on the heel. This is extremely common at speed and in collected work, particularly in young or green horses. Bell boots also protect shoes from being pulled off. They come in pull-on rubber versions (no closures, extremely durable) or no-turn versions with velcro or buckle closures (easier to put on and take off, but with a risk of rotating and rubbing). For horses with active overreach problems or during jumping or fast work, bell boots on the front feet are essential.
Sport Boots / Support Boots
Sport boots provide both splint protection and tendon/fetlock support in a single boot. They are the preferred choice in many disciplines, including reining, cutting, barrel racing, and team roping, because they protect the cannon, splint bones, and flexor tendons simultaneously. Higher-quality sport boots incorporate strike-resistant materials (ballistic nylon, impact-resistant polymers) over a neoprene or fleece lining. The fit is critical — a boot that wrinkles inside creates pressure points, and a boot that twists or shifts during work provides incomplete protection.
Skid Boots
Specific to reining and ranch horse competition, skid boots protect the fetlocks of the hind legs from the ground surface during sliding stops. When a reining horse performs a correct sliding stop, the hind fetlocks flex deeply and can contact the arena sand. Skid boots prevent rope burns and abrasions from repeated contact. They are worn only on the hind legs and should be fitted with the cup over the back of the fetlock joint — not the front.
Polo Wraps
Polo wraps are stretch bandages that provide light support and protection to the tendons and splint area. They are widely used in polo, English flatwork, and lunging. Their advantage is conforming precisely to any leg shape. Their disadvantage is that incorrect application — too tight, uneven tension, or wrinkles in the fabric — can create pressure injuries worse than no wrap at all. Polo wraps should only be applied by someone who has been properly taught the technique. They are generally not suitable for inexperienced horse people to apply unsupervised.
Tendon Boots (Jump Boots)
Tendon boots are used primarily in jumping disciplines. They have an open front (allowing the horse to feel the fence rail and "respect" the jump) and a reinforced back that protects the flexor tendons from a striking hind foot during bascule over a fence. The open front is a deliberate design choice — the theory is that the horse learns to be careful with its front feet when it can feel contact, making it a more careful jumper over time.
Fit, Application, and Heat Management
Every boot must be fitted to the individual horse's leg. Too tight risks restricting circulation and creating pressure injuries. Too loose shifts during work and provides incomplete protection — or becomes a hazard if the boot catches on something. Always check all closures after a few minutes of work and readjust if needed.
One concern with synthetic boots worn during hard work is heat buildup. Research has shown that certain boot materials trap heat and can raise tendon temperature significantly during exercise — a potential concern for soft tissue health. The mitigation is to remove boots promptly after work and hose the legs with cool water if the horse has worked intensively. Some trainers prefer to work without boots during regular schooling sessions and use them only during high-risk activities (competition, jumping, sliding stop work) for this reason.
Always clean boots thoroughly after each use. Dirt and grit trapped inside a boot creates friction that can cause rubs and infections. Inspect for cracks, worn closures, or degraded padding — a boot that fails during work provides no protection and can create its own hazards.
