Brand New Mountain Horse Sz 9. Your feet (and boots!) do an enormous amount of walking when you look after horses. Back and forth to the muck heap down to the tack room or your car into the feed store; in mud slush and manure. That means that just like the song your boots need to be made for walking as well as riding. Mountain Horse has designed a strong comfortable boot specifically to meet your needs. See pictures for one flaw on toe.
