Abstract: A swimming fin is provided to reduce user's fatigue by reducing water resistance and to increases propelling force by increasing lift of the swimming fin. The swimming fin includes a shoe portion(10) and a pin portion(20). A first protruding portion(21) is formed on a center portion of any one of upper and lower surfaces of the pin portion(20) to extend in a longitudinal direction of the pin portion. At least a couple of second protruding portions(221,222) are formed to extend in a longitudinal direction of the pin portion(20). The space between the first and second protruding portions(21,221,222) gets narrower as it goes away from the shoe portion(10).
