What is a Monofin?

A monofin is a single, large fin used by swimmers to enhance their propulsion through water. Unlike traditional fins, which are worn on each foot separately, a monofin is designed to bind both feet together, creating a single, unified extension of the body. This design allows for more efficient and powerful movements, mimicking the motion of marine animals like dolphins and whales. Monofins are commonly used in sports such as fin swimming and free diving, where speed and streamlined movement are crucial. They are also popular in recreational swimming, particularly in mermaiding, where swimmers wear mermaid tails equipped with monofins.
