Abstract
A flipper for swimming or underwater activities or muscular training, includes a blade and a shoe, the ends of which facing one another are dynamically and kinematically separate. The blade has extensions projecting backwardly and fixed to the shoe in areas substantially corresponding to its central part. Elastic tier rods are provided between the blade and the front part of the shoe and are designed to control angular variations between the blade and the shoe.
