Swimming fins help to provide a more powerful kicking motion, propelling you through the water faster, and requiring less kicks or strokes to travel the same distance than when swimming without fins. The use of swimming fins also improves ankle flexibility and range of motion, helps to develop a naturally more powerful kick, and improve kick pace and tempo. Understanding the different types of swimming fins enables you to purchase the type that best suits your swimming style and needs.
Short Swimming Fins
Short fins create resistance in the water while requiring you to kick faster. They provide a long, intense workout that increases your kick power, helps you increase your kick tempo, and allows you to build your endurance. Backstrokers and freestylers commonly use short fins. Using these fins also helps you to develop an optimal kick technique, improving your swimming performance.
Long Swimming Fins
Long fins are the fin type of choice for beginner swimmers because these fins cut through the water reasonably easily, and the increased length increases the rate of your forward propulsion, requiring you to expend less energy. The use of long fins also helps you to pull your hips up to the surface of the water and keep them there, which promotes proper in-water body positioning. This streamlines the body in the water, creating less drag, and helping you to improve your performance, technique, and speed. Snorkelers, recreational swimmers, children, and divers benefit from using long fins.
Notched Swimming Fins
Notched swimming fins have a v-shaped void and are also known as split fins. The blade of the fin is split from the toe of the shoe portion to the outer edge. Serious swimmers, such as those who compete, use split fins because they mimic the natural motion of the foot as it moves through the water. Split fins are short and provide moderate to fast speeds with moderate effort, so have little resistance. These fins make a great choice for those with weak knees and ankles, as the decrease in resistance puts less pressure on the knees and ankles, while still providing a solid workout. These blades help you to establish a proper kick technique that significantly improves your performance in the pool.
Mono Swimming Fins
Mono fins have a single blade and force you to hold your feet together as you kick. This allows you to learn and improve your butterfly and dolphin kick techniques. Keeping the feet together and kicking in butterfly or dolphin style greatly increases your core strength. Additionally, the large single fin creates greater resistance, providing an intense workout that improves your strength and endurance.
