‘跑蹄’ is a verb meaning 'to stamp with hooves' — specifically describing the forceful, rhythmic striking of the ground by a horse’s or other hoofed animal’s hooves. The first character 跑 (páo) here is not its common meaning of 'to run', but rather an archaic or literary variant used in compound words related to equine movement; 蹄 (tí) means 'hoof'. Together, they form a vivid, onomatopoeic-sounding term emphasizing the audible, percussive action of hooves hitting hard ground.

This word appears mainly in descriptive writing — poetry, classical-influenced prose, or narrative accounts of horses — rather than everyday speech. It evokes energy, agitation, or readiness: a horse might 跑蹄 before galloping, when impatient or alert. It is rarely used for animals other than horses, donkeys, or mules, and never for humans or non-hoofed creatures.
