I've owned several pairs of vented fins including the SP Jets I've been diving for a couple of years. I've never questioned the "performance enhancing" properties of the vents in fins that the companies claim, but how do they actually work? They supposedly relieve the leg muscles on the kick return, but how? I'm under the assumption that the quadraceps(sp?) are the strongest, least tiring, muscles used in the kicking motion. The return kick, using your butt muscles, seems to be the weakest portion on a kick cycle. The way the vents are facing, and assuming forward momentum in the water, they seem backwards on the SP Jets of what they should be.
I just don't see how the water is actually routed through the vents and at what point. How does this really help the process of kicking?
Thanks,
