thinking on one's feet
Spontaneous mental agility
Thinking on one's feet is responding quickly and effectively without preparation—improvising under pressure.
The image is of someone who must act while standing, without time to sit and deliberate: Good trial lawyers can think on their feet when witnesses say something unexpected.
The phrase emphasizes mental agility rather than rehearsed knowledge.
