 ### Cast iron would be a very poor material for a horseshoe due to its
brittleness and stiffness. Horseshoes need high impact resistance and a
little bit of flex to stay attached to the hoof which is why they are
relatively thin and made of forged iron or steel. A cast iron horseshoe
strong enough to resist shattering would be very heavy.
