As a general horses, horses do not need to have shoes nailed on in order to be sound and rideable. Diet and trim play a large part in helping the horse to build a strong, healthy foot that is better known as a rock cruncher. If you are working towards healthy feet, things such as boots, casting, glue on shoes, and formahoof can be helpful in the interim to keep your horse happy and sound. A low starch diet, made up primarily of forage, with balanced minerals, is ideal to helping to build a healthy foot.
