I've starting swimming again after about 8 years off. I'm trying to get back into shape to lose a little weight and hopefully start competing again! Anyway, when I was swimming I'm pretty sure we all just used big fins. Now it seems there's about 100 different types (long, medium, short, really short, some have holes, etc). I have been thinking about buying some, but I'm lost. Maybe I shouldn't even use fins? Any suggestions?
