Swimming device, characterized by being constituted by two blades (1, 2) articulated with each other so that they can be opened until both are placed in the same plane and closed so that they are arranged substantially parallel, this device being adapted for its application to the legs below the calf of the swimmer, so that when moving the foot in the water backwards, said articulated blades open, offering a high resistance to water and thus favoring the impulse, while moving the foot forward, said blades are closed by the friction of the water, thus offering reduced resistance to advancement.
