Horses will usually require Gaiters if they have sensitive skin or are travelling excessive distances. There are two types of Scoot Boot gaiters, Trail Gaiters and Endurance Gaiters.  The Trail Gaiter protects the top of the horse’s heel bulb to prevent rubbing on sensitive skinned horses, or for horses travelling excessive distances. We recommend using Trail Gaiters when your horse is getting used to Scoot Boots. The Endurance Gaiter protects the lower back of the pastern and the rear coronet area to prevent rubbing for sensitive skinned horses and for endurance horses travelling excessive distances.
