A horseshoe for horses, in particular for racehorses when taking part in competitions. The horseshoe is produced from thermoplastic polymer material or from fiber-reinforced thermoplastic polymer material. The thermoplastic polymer material is selected from thermoplastic polycarbonates or fiber-reinforced thermoplastic polycarbonates. The horseshoe may be constructed from a core of fiber-reinforced plastic material, which is sheathed in a functional layer made of plastic. The core may also be formed from a fiber-reinforced thermoplastic polymer material, such as a fiber-reinforced thermoplastic, and the functional layer may be formed from a thermoplastic polycarbonate material or a fiber-reinforced thermoplastic polycarbonate material, such as a thermoplastic or a fiber-reinforced thermoplastic. The horseshoe may be produced by thermoplastic injection molding methods.
