Shadowless feet makes full use of the martial arts proverb: "let your mind lead your ch'i and your ch'i move your power." Letting your ch'i flow down to your feet, you kick vigorously without any preparatory movements. You don't go flying around on hidden suspension cables like in the movies.
完全發揮武諺中「以意領氣，以氣領力」的精髓：將氣貫穿到腳上，在沒有預備動作下發勁出腳，並不是電影裡吊鋼絲的凌空飛腿。
