Why do underwater divers wear flippers on their feet.?

Underwater divers wear flippers to enhance their propulsion and maneuverability in the water. The wide, flat surface of the flippers allows divers to push against the water more effectively, enabling them to swim faster and with less effort. This reduces fatigue and helps maintain stability while diving, making it easier to navigate underwater environments. Additionally, flippers provide better control during tasks like diving, resurfacing, or changing direction.
