A horseshoe with a stabilizer-feature and splaying has a U shaped metallic unitary body with left-right wings and an integral compliant leaf-spring disposed proximate to or in the horseshoe toe area. The leaf-spring may be crescent-shaped or chord-shaped and resiliently deforms upwards, exerting sideways-pressure causing splaying of the left-right wings. The leaf-spring may have a groove on either side to assist preparation before horseshoe installation. The crescent-shaped leaf-spring forms a cavity with the hoof underside in use, which cavity is optionally filled with a resilient material, e.g., silicone, obviating accumulation of dirt/debris. Stabilizers comprising a plurality of rows of beads formed integrally with the horseshoe bottom form a negative camber on the horseshoe-underside. The stabilizer rows may be staggered and assist in the stability of the horse during racing, especially at track-curves. The horseshoe may be cast/forged, blanked, or welded and can be mass-produced. Preferably, the horseshoe comprises hardened spring steel.
