The Natural Balance Shoeing (NBS) system involves the use of a special shoe with a squared rocked toe that is attached as far back from the toe as is possible. The aim is to mimic the natural shape of hooves on feral horses; by bringing the breakover point further back and allowing the hoof to experience wear at the toe (which protrudes over the shoe) the joints and ligaments are reported to be subject to less stress and the hoof at the toe does not increase in length between shoeings.
