A swimming aid device comprising of a convertible bi/mono swim fin containing a first fin, a second fin and coupling means. The present invention can be used as traditional independent swim fins or combined together to form a bi-swim fin in which both swim fins are held together to aid the swimmer in performing feet unison-style swim kicks such as a dolphin kick. In one embodiment, the coupling means consists of a track and rail in which a track is attached to a first fin and a rail is attached to a second fin. Said track of the first fin has an inner groove that can slidably receive the rail of the second fin. The swimming aid device further comprising a locking means for selective locking of the rail to the groove so that once the rail is slidably and fully received within said groove, said locking means prevents further relative sliding movement between said rail and said groove.
