A nail for fixing a shoe to a hoof includes a head (20), and a shank (12) extending from the head (20) generally along a centreline (14) and terminating in a tip (13). A reaction region (24) is formed in the shank (12) adjacent the tip (13) and has a flattened profile having front and rear surfaces (25, 26) interconnected by respective edge surfaces (27, 28). In the reaction region (24) the front surface (25) is convexly curved to incline the front surface (25) relative to the centreline (14) of the shank (12) and the edge surfaces (27, 28) converge relative to each other towards the tip (13), whereby, on forcing the nail into the hoof, the reaction region (24) is adapted to produce a resultant force on the nail caused by engagement of the reaction (24) with the hoof, the resultant force being adapted to predispose the nail to bend about the rear surface (26) of the reaction region (24). Also disclosed are processes for forming a horseshoe nail.
