A heel grab is an injury to the heel area of a horse’s hoof, typically occurring when one hoof strikes the heel bulbs or the back of the hoof capsule on one of the other hooves during movement. It is a common overreach injury in horses and can range from a superficial scrape to a deep wound requiring veterinary attention. Understanding how heel grabs occur and how to prevent them is an important part of equine hoof care.
How Heel Grabs Happen
During extended gaits — particularly canter and gallop — some horses have a movement pattern where the hind hoof overreaches and strikes the front hoof before it has fully left the ground. This is sometimes called an overreach or a “strike”. When the hind toe catches the heel of the front foot, the result is a heel grab — a cut, bruise, or tear to the heel bulbs, the soft tissue at the back of the hoof, or the heel of the shoe if one is worn.
Horses with long, low-set hooves, long pasterns, or those that are naturally very “overtracking” (where the hind foot lands significantly in front of the forefoot print) are more prone to heel grabs. Tiredness also increases the risk — a horse working towards the end of a long session may lose the precision of its footfall and start overreaching more frequently.
Signs and Symptoms
A fresh heel grab is usually immediately obvious: blood at the back of the front hoof, a torn or detached shoe, swelling in the heel bulb region, or lameness. The horse may pull up sharply or show reluctance to weight-bear on the affected leg. Milder heel grabs may only produce bruising that becomes apparent in the following 24 to 48 hours as heat and tenderness develop.
Repeated heel grabs in the same area can produce chronic scarring, thickening, and sensitivity in the heel bulbs. If left unaddressed, the ongoing trauma can affect the horse’s way of going and willingness to move forward freely, particularly in work requiring extended movement.
Treatment
For minor heel grabs, clean the wound thoroughly with an antiseptic solution, apply a wound dressing if needed, and monitor for signs of infection — heat, swelling, discharge, or worsening lameness. Most superficial heel grabs heal within one to two weeks with appropriate care.
Deeper wounds, wounds near the coronary band, or any injury that causes significant lameness should be assessed by a veterinary surgeon. Damage to the coronary band can affect future hoof growth, potentially causing long-term changes to the hoof capsule. Wounds in the heel area are also at higher risk of contamination and infection, given their proximity to the ground.
Prevention
The most effective preventive measure is the use of overreach boots (also called bell boots), which are rubber boots worn over the front hooves to protect the heel area from the hind toe. These are widely available and should be used as standard for any horse that has a history of overreaching, particularly when jumping, working at speed, or travelling in a trailer.
Farriery can also help. A qualified farrier can address hoof balance issues that contribute to overreaching — for example, rolling or squaring the toe of the hind shoe to reduce the leverage that causes the hind foot to strike early. Regular trimming and shoeing intervals (typically every six to eight weeks) prevent hooves from growing out of balance. See also: hotshoeing for information on farriery techniques.

Frequently Asked Questions
Are some breeds more prone to heel grabs than others?
Yes. Warmbloods and sport horses with big, ground-covering gaits are more likely to overreach than short-striding native breeds. Thoroughbreds, particularly when fit and free-moving, are also commonly affected. However, any horse can grab its heels if working on soft ground that slows the front foot’s departure, if unfit and tiring, or if conformationally predisposed through long hooves and low heels.
Should I use overreach boots all the time?
Not necessarily. Many horses only need overreach boots for specific activities — jumping, working on soft ground, or hacking in muddy conditions where the front foot tends to stick. Wearing boots constantly can cause rubs if not correctly fitted and can trap moisture and debris against the hoof. Assess your horse’s individual risk and use boots where the likelihood of overreaching is highest.
Can a heel grab affect the coronary band?
Yes, and this is the most serious potential consequence. The coronary band runs around the top of the hoof capsule and is responsible for producing the hoof wall. Damage to the coronary band can cause a permanent groove, indentation, or crack in the hoof wall as it grows down. If a heel grab has caused injury close to or involving the coronary band, involve your vet promptly to minimise the risk of long-term hoof changes.
