Tendon boots, are used on the front legs for protecting the tendon area of the horse's front leg from strikes from the hind hooves that can occur when the hind leg extends forward towards the front leg such as when cantering or on landing whilst jumping. They also offer protection to the inside of the legs from brushing injuries.

Open-fronted tendon boots are popular with show jumpers as they provide protection to the tendons whilst still allowing the horse to feel a pole if it brushes or knocks it whilst jumping so that is encouraged to be more careful next time.

Closed tendon boots however should be used when eventing as in addition to the risk of tendon injury there is also a high risk of injury to the front the legs from the solid fences.

Tendon boots often have a hard moulded plastic outer shell but may also be made of leather or other material and should be placed high enough to protect the tendon and extend low enough to protect the fetlock joint.

Leather tendon boots tend to have straps and buckles to fasten them, but synthetic tendon boots are usually fixed with several velcro fastenings which fasten around the horse's leg or which pass through a ring and fasten back on themselves. Some have double velcro straps that overlap and these are more secure than single velcro straps. Tendon boots with velcro fastenings make putting on and taking the boots off quick and easy, and are more adjustable than straps and buckles.

Tendon boots should have a soft lining to prevent any soreness occurring and it is important that the tendon boots fit the horse comfortably to avoid any rubbing. There are tendon boots available with fleece or skeepskin lining for extra comfort and these linings may be removable for easy cleaning. Tendon boots will inevitably get dirty and so it is important that they can be easily and regularly cleaned.
