This preferred method is retarded, if it means footwear for climbing takes precedence to fin function IN the water.
If you have to dive this boat, ignore the stupidity and wear a good par of freedive fins with an open heel pocket....The DUI Rock boots are junk too, unless you have ankles the size of toothpicks and have to walk around with double 130's and stages
Having a boot this enormous cuts down your feel and contact with the fin--power transfer in the water should be the holy grail, not wandering around in jungle boots some shop told you to dive with ....
These
DiveR Australia: Equipment are the optimal fins for scuba diving in open water ( but not for cave or deep shipwreck penetration).
You use a pair of booties that are reasonably slimline, and have a freedive shop put custom Riffe open heel foot pockets on the blades. Here in Forida, one of the best places for this is
https://www.flfreedivers.com/ ( they sell these fins, and do the custom footpockets).
Even with my DUI tls 350 drysuit on, using these fins I can keep up with most scooter divers.
There is a "spectrum" out there of how functional divers are in the water...you can be at the end where you can beat any current, and effortlessly swim around like a fish or dolphin built for the environment, or you can be on the other side of the spectrum, more like a diver off the platform with no fins on at all, and completely helpless and pathetic.....this being essentially what the short fins would get you "closer to" in the spectrum.
With the DiveR fins, you can swim at a mild pace, have ridiculously low SAC rate from the lack of exertion you have to swim with your short fin buddies, AND when something happens and you need to move, YOU will be able to handle this easily.
