You should use purpose-made horseshoe studs for horses and choose the style according to your riding discipline and the type of ground you usually ride on. If you ride on the road or rocky trails, use road studs. If you ride on hard, dry grass, use grass studs. If you live in a place with lots of rain and soft ground, you should use mud studs. If you take part in riding disciplines that require tight turns, such as jumping and dressage, you should use larger studs than if you perform on the straight.
