Fins diving is a special tool worn on the legs to improve the performance of swimmers in the water. Typically used in a variety of water-based activities, including swimming, snorkeling, diving, and even some forms of water aerobics. These fins are designed to increase thrust, maneuverability and efficiency while swimming.
In addition, fins can also help swimmers focus on kicking techniques. By providing additional resistance, these fins allow swimmers to feel their foot movements more clearly, helping them perfect the kicking force.
