A bell collar — also called a bell boot in most modern equestrian usage — is a protective rubber or PVC boot shaped like an inverted bell that fits over the horse’s hoof and pastern. It is designed to protect the heel bulbs and the coronet band from being struck or overreached by the hindfoot — a common injury risk during fast work, jumping, or when a horse is working with energy and forward drive. Bell boots are one of the most widely used items of protective leg equipment in everyday equestrian management.
What They Protect Against
Overreaching occurs when a hindfoot strikes the back of a foreleg — most commonly the heel bulbs, the coronet, or the back of the fetlock. It is a significant risk in horses that move with a long, forward-reaching stride, those that are tired or working on deep or slippery going, and horses jumping or galloping at speed. The injury from an overreach can range from minor bruising and grazing to a serious wound that severs the heel bulbs or damages the coronet band. Because the coronet band is involved in hoof growth, severe injury in this area can affect the quality of hoof produced for months or years afterwards.
Bell boots provide a physical barrier that absorbs the impact of the hindfoot making contact with the foreleg. They do not prevent overreaching occurring — only improved training, fitness, and shoeing can do that — but they significantly reduce the severity of the resulting injury.

Types of Bell Boot
Bell boots are available in several constructions and fastening styles.
Pull-on boots are made from solid rubber or neoprene without any fastening. They are stretched over the hoof and held in position by their own elasticity. They are inexpensive, durable, and cannot come undone during work, making them popular for turnout. The disadvantage is that they can be difficult to pull on and off, particularly on horses with large feet or when the boot is new.
Velcro or quick-release boots have one or more Velcro straps or a petal-style overlapping design that opens fully for easy fitting. They are quicker to apply and remove, which suits busy yards and competition environments. The trade-off is that the fastenings can come undone if caught on a fence or during exuberant turnout.
Petal boots consist of overlapping rubber or plastic segments that provide a degree of articulation and are less likely to be pulled off than solid boots if a horse stands on itself. They are popular for high-level jumping horses.
When to Use Bell Boots
Bell boots are appropriate for any horse at risk of overreaching. This includes horses in regular jumping or galloping work, those being schooled in collection (where the hindleg reaches further under the body), and horses turned out in deep or muddy fields where footing makes them more likely to catch themselves. Many competition grooms fit bell boots as standard for all work during the jumping or eventing season, removing them only for dressage phases where a cleaner silhouette is expected.
For everyday hacking, the decision depends on individual risk. A horse with a known history of overreaching, one recently returned to work after a lay-off, or one working on challenging terrain would benefit from bell boots. The BHS guidance on leg protection suggests basing the decision on the horse’s conformation, way of going, and the nature of the work.
Fitting and Care
Bell boots should fit so that the lower edge sits just below the coronet band when the horse is standing normally, providing full coverage of the heel area without trailing along the ground or restricting movement. If a boot is too long, it will be stepped on; too short, and it leaves the heel bulbs exposed.
Rubber boots should be checked regularly for cracks, splits, and loss of elasticity. Stiff, cracked rubber can cause rubs and pressure sores. Boots should be washed after use, allowed to dry fully before storage, and replaced when they show significant wear.
Frequently Asked Questions
Can I leave bell boots on for turnout?
Pull-on bell boots are commonly used for turnout and are generally safe for this purpose. However, any boot left on a horse at turnout should be checked daily for rubbing, accumulated grit or debris, and signs of wear. Boots that slip and rotate can cause pressure sores in the coronet area. If your horse is in a small paddock with good footing and a low overreaching risk, removing boots for turnout may be preferable.
Do bell boots cause rubs?
They can, particularly if they are ill-fitting, poorly maintained, or worn continuously without removal. The rim of a pull-on boot can rub the coronet band if the boot sits too high. Velcro-fastened boots can chafe if the straps are not secured flat. Check the coronet and pastern area regularly for signs of hair loss, redness, or skin irritation. If rubs are occurring, try a different style or size, and consider using a barrier product on the coronet before fitting.
Are bell boots the same as overreach boots?
Yes — bell boots and overreach boots are the same item. The two names are used interchangeably throughout the UK equestrian world. “Bell boot” describes the shape (resembling an inverted bell); “overreach boot” describes the purpose (protecting against overreaching injuries). You will see both terms in catalogues, at trade stands, and in general yard conversation.
