SWIMMING FINS

- Swimming fins help the wearer to move through water more efficiently, as human feet are too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high-frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful for bodysurfing.

- Swimming fins are designed to help swimmers develop a more powerful kick, increase their kick tempo, and improve ankle flexibility. They also help swimmers move through the water faster, which makes them a very attractive piece of swim equipment.
