It's not for swimming it's a strengthening exercise, like lifting weights in the gym. And as you said it IS FUN!
I think fins make me use my whole foot more when I'm not using them - kinda like Michael Phelps and his HUGE feet.

One of my favorite pool exercises is with fins and a kickboard. I hold the kickboard perpendicular to my chest and facing away from the direction I'm swimming, I hold my legs perpendicular to my torso and kick with nice straight legs. MEGA abs work out!

The fins help me with some drills. They give extra propulsion so I don't sink. I can concentrate on my arms or body position or whatever without having to worry about my kick as well.
