On the other hand, Although I have been making both working and pleasure dives with my freedive fins the last year, I am shopping for a pair of Mares full foot dive fins.
The fact is Mares makes some of the best fins in scuba diving, Freedive fins are not for most scuba divers, or even most scuba dives for a majority of divers.
Mares "is" better than most mfg's at making fins. The "reason" freedive fins are not used by most divers, has much more to do with pervasive attitudes in the dive industry, about "how you teach someone to dive, and what gear to start them in". In order for freedve fins to gain the dominance they deserve, you would need to actually teach REAL bouyancy and perfect trim to new divers, so that they naturally swim flat/horizontal....., and if they need to get their heads closer to macro life, they inflate the wing/bc a little, so that they can maintain a fin-up, head slightly lower posture while swimming close to the bottom ( again, for slow motion macro level diving). But since they would have been taght to choose a Bc and gear properly for ultra low drag, they would immediately feel the advantage of a freediving kick and glide, given the required coordination for the fins.....which brings up one more point--so many brand new divers begin with no coordination, and never end up with any real diving coordination. Some could never have it, some could be taught to kick properly, if the instructor "knew" how to use freedive fin techniques. Again, most DO NOT. The sad thing here, is that because of failures in instruction and dive shop gear choices, most new divers are started with bogus gear, and poor training--just the minimum to get by. This is confirmed by the huge concentration of brand new divers swimming HEAD UP, FEET DOWN ( totally the instructors fault for not pushing them into a proper BC/wing choice, and not configuring weighting properly, or teaching then proper trim techniques)...and punctuated by all the conversations you hear about how so and so's fins are too negative, and that they need more bouyant fins--when all they need is different weighting on their body to get the torso heavier, and the waiste area lighter.
You have countless boat captains that like to get "righteous" about how the divers on their boat should not be using freedive fins over the delicate corals on some dive areas, but this stupidity is about confusing terrible technique and bouyancy/trim control, with choice of fins. A scuba diver with DIR style trim, can easily use freedive fins over delicate corals, and cause zero damage..and still enjoy the freedive fin superiority while moveing from location to location, acorss whatever larger spaces the divers need to cross over.
Walking with fins on aboard the charter boat is also harder for a brand new diver, as there is MORE to maneuver. It is easy with practice, just harder the first few times..and you buy the fins for swimming anyway, NOT for walking.
You could ask a new diver to honestly assess whether they are a well coordinated person, or NOT....If the answer is NOT, then the choice of fins might reasonabbly be along the lines of the Superchannels or Avantis....if they say, "yes", I am well coordinated, and learn most sports skills easily", then they should be pushed into freedive fins, given an instructor with the requisite knowledge and skills with freediving fins.
