They are, in that vain you could duct tape two fly swatters on your booties and they would be very easy on your legs!
I own a pair of Oceanic Split-fins and use them with my Dry suit and they suck! No stability, trim, control, and try to hold up a 45lb camera in the vertical position! Give me a good blade anytime! Even better for swatting flies! They have no reason to exist other than to sell people a gimmick to take the place of good pool or water work! If you do 500 meters a day with your blades you will feel better and be in better shape as well as have better skills! Trade the split-fins for a gym membership!
