The present invention concerns articulated flippers for hands and feet, with a variable surface during swimming, for use by an amateur or a professional, as well as for subaqueous swimmers. These flippers can be used for different swimming styles, such as crawl, swimming on one side, etc. Shoes of various types which are to be put on the feet, and gloves or mitts which are to be put on hands, are used with ribs connected in a hand articulated-joint connection to the shoes and prolongations provided on four fingers of the gloves. The ribs, connected in articulated-joint connection to the shoes or wooden-shoes, and the prolongations for the fingers, support a cartilagineous surface which can open and close during swimming, thus allowing a variation of the friction surface with the water.
