SwimFin is the ultimate swimming aid - the first truly new development in the teaching of swimming for decades - tried and tested to assist anyone in learning to swim. Unlike arm-bands and swimming-rings, which keep the body upright, SwimFin works in harmony with the body, helping to develop a better swimming position. Unlike kickboards and floats, SwimFin leaves the arms free to move, significantly speeding up the learning of front-crawl, breast-stroke and butterfly. It even works for back-stroke.
