Studs are used in your horse’s shoes to give added grip, mainly when the horse is working on grass. They are not just used when the going is wet. Hard ground can have poor cover and can become very greasy and slippery after just a little rain. Studs can make the difference between your horse working or jumping confidently or, if studs are not used, slipping and worrying about their foot placing. Studs come in different shapes and sizes and it depends on the ground conditions and the horse's way of going as to which you use.
