Good larger fin for long distances Review by 2airishuman
I have these and have used them for snorkling.
These are longer fins that provide speed and efficiency when moving longer distances. They do not give the convenience or control that shorter fins provide. I like them for what they are, but may also get some smaller fins. (Posted on 12/13/15)
