If you want to describe someone who moves with less weight or effort than being "more heavyfooted," you could use antonyms such as light-footed, nimble, agile, graceful, or fleet. These terms suggest someone who can walk, run, or dance with ease, balance, and speed. A light-footed person might seem to float on air, barely making a sound, while a nimble one might dodge obstacles or leap over them. An agile person might have quick reflexes and precise movements, while a graceful one might have a poetic gait or posture. A fleet person might cover long distances in a short time, as if flying. By using antonyms, you can expand your vocabulary and convey a more nuanced impression of people's physical abilities.
