Embodiment Construction

[0027] first reference figure 1 , the swimming fin is generally identified by the reference numeral 100 . Swimming fin 100 may include an in-line for receiving a swimmer's foot. figure 1 A full boot or shoe or open foot pocket 110 is shown. A heel strap may be provided to secure the swimmer's foot in the foot pocket 110 . Fin blades 114 may extend from foot pocket 110 . Fin blade 114 may include a substantially planar surface for directing water flow across swim fin 100 . The fin track 116 may extend along the lateral edges of the fin blades 114 . The foot bag 110 may include a ventilation area 118 to minimize parachute when moving through the water and also to minimize suction when removing the user's foot from the foot bag 110 .

[0028] now refer to image 3 Furthermore, swim fin 100 may include a relatively rigid base chassis 120 that may be bonded to foot pocket 110 during the injection molding process. In contrast to the relatively flexible fin blade 114 (which ma...

Abstract

The invention relates to a swimming fin. The swimming fin may include a foot pocket configured to receive a foot of a swimmer and a fin blade extending from the foot pocket. A relatively rigid base base may be bonded to the foot pouch. The fin blades may be relatively flexible. The fin track may extend along a lateral edge of the fin blade. The fin track may include a fin ridge including a plurality of fin ridge segments in a linear configuration. The fin ridge may be configured to provide predetermined hydrodynamic characteristics for the swimming fin. The swimming fin may flex within a maximum angle of attack, which may be variable and dynamically varies within a predetermined range of maximum angles of attack as a function of kicking force generated by the swimmer during the kicking cycle.
