Ergoniomical flippers for swimming or diving include a nautical shoe and a fin forming a single part of the same material. The fin extends from the sole of the nautical shoe with an inclination of about 45° with respect to the front area of the sole or tip and from an intermediary position between the middle of the sole and the tip. It is also provided with a triangular prismatic reinforcement both at the front and rear areas respectively of the junction between the sole and the flipper or fin, thereby forming a single part. Also, minor sides of each reinforcement are in contact with the sole and the fin.
