The term splay footed describes the toe structure of a horse. An equine’s toes can be pointing inward (pigeon feet) or outward (splayed foot). In the latter case it will swing the hoofs inwards while running. This style of run is known as winging and is the opposite of paddling. These horses are also likely to have narrow chests and will make contact with the back legs while running. This increases the chances of suffering fetlock related injuries.
