Swim fins are used to increase propulsion, allowing a swimmer to move more quickly and easily through the water.
They are a common piece of equipment for swimmers of all levels to improve technique, build leg muscle strength, and increase endurance.
Fins can help a swimmer maintain a more streamlined body position, which reduces drag and improves overall efficiency.
When choosing fins, it's recommended to select a pair that is a bit tighter, as they will slide more on your feet when wet.
