A new horseshoe has two legs connected by a bridge, the bridge having a pair of physical markers provided directly opposite one another in both a support surface and a ground surface, the pair of physical markers providing a guide for cutting through the bridge of the horseshoe. A method of applying the horseshoe includes fitting the horseshoe to a hoof, attaching the horseshoe to the hoof, and dividing the horseshoe in two parts by cutting through or sawing through the bridge along the physical marker in the ground surface of the horseshoe. A method of upgrading a horseshoe involves providing a pair of physical markers on a bridge of the horseshoe at positions directly opposite one another both on a ground surface and a support surface of the horseshoe.
