A swimming fin comprising a blade (1) in a relatively stiff material extending from a shoe (7) of incomplete development at the rear in a relatively soft material and a strap (6) of adjustable length connected to the shoe for wrapping at the rear the foot of the swimmer. From the rear side of the blade there extends a concave sole (2), the shoe (7) being connected to the top face thereof, and to the sides thereof flaps (4) extend to which the ends of the strap (6) are connected. The swimming fin further comprises a longitudinal strip (11), in a material of intermediate stiffness between that of the blade and that of the shoe, extending along the top face of the blade (1) and above the shoe (7) to connect the blade and the shoe therebetween.
