I was thinking about getting a pair of full foot pocket fins for warmer water scuba diving. My dive shop said it's a bad idea, as they won't be efficient enough, when compared to the open healed variety. Their basic recommendation is that if you're not snorkeling, then full foot is no good. Any advice either way?? I've heard good things about the Aeris Velocity!!!
Froggs,
I am also thinking that a set of full foot fins would be a good idea for warm water diving, but only boat diving. I would still stick with open heel fins & boots for warm water shore diving.
I am recently back from a 10 day liveaboard trip to Cocos Island. I used my Apollo Bio-Fins with boots on that trip. Cocos condiitons can be highly variable, and we encountered moderate to strong currents on a number of dives as well as strong surge on a number of dives. Although I was not uncomfortable with my Bio-Fins, there were a few instances where I felt I would be happier with a stronger fin in the currents. Note that my Bios are the original soft rubber type.
On this trip I noted that both of our divemasters and a number of the more experienced divers (one with over 5000 dives) were wearing full foot blades and that got me to thinking it might be a good idea to consider.
I disagree with your LDS's opinion that full foot fins are not as efficient as open heel designs. Head to head tests seem to indicate otherwise.
Advantages:
Less weight and less gear to carry (i.e. no boots) - weight is becoming a real issue with airlines
As good or better performance than open heel designs
Low cost
Ease of donning and doffing. Some might argue on this - but it seemed to me that the full foot users really did have it easier.
Disadvantages:
Possible blisters or hot spots - can probably be solved with a pair of lycra socks, which I wear under my booties anyway for the same reason.
Loss of traction when transferring from main boat to panga - here the boots are probably the best choice. Bare feet are pretty good, but I certainly would not want to be walking around in the lycra socks! Will have to put them on in the panga if wearing them is necessary.
Sand in foot pocket - not too likely since I don't put my feet on the bottom except in rare circumstances. Even if it happens, it seems like taking the fin off and putting it back on when submerged is going to be pretty easy.
That said - I am planning to get a new set of full foot blades, probably the Mares Avanti Superchannel, for warm water boat diving.
I'll also keep my Bio-Fins for trips to Bonaire, etc.
