Martial arts' kicking expertise, usually used in reference to performers in Hong Kong martial arts films. A fine use of legs and kicking (as opposed to flips, punches, wire-fu etc) is called bootwork. Usually this occurs when the performer is actually trained in kickboxing or taekwondo rather than wushu or Peking Opera.
"Billy Chow's bootwork in the final showdown of Pedicab Driver is excellent"
