Horse studs screw into specially-made threaded holes in your horse’s hind shoes. Your farrier can create these holes for you. Screw horse studs in to provide extra grip in deep going and wet, slippery conditions. This can give a competition horse the edge for racing, hunting, point-to-point, or XC work. Horse studs are a temporary solution to prevent slipping. You should remove them when not in use. Ironically, they can cause slipping on hard surfaces e.g. roads.
