Frog-kicking full foot fins

Does anyone have any experience with frog kicking in full foot fins?
Unfortunately, no-one seems to do a full-foot Jetfin!

I would be grateful to know of fins that work with a frog-kick and fins that
don't.

Thanks

Iain

Sure, I frog-kick in Riffe Silent Hunters (rebranded Omer Millennium
fins) all the time. Their characteristics are obviously different from
Jetfins, but the basic motion is the same and allows you to self-propel
in environments where vertical space is limited (in my case usually when
I'm passing over a shallow reef).

Why not buy a selection of boots?

The name Jet Fin is a trademark. As I imagine you know, there's more than
one similar fin using the pocket and strap design with a vented blade.
While I don't know of any full foot Jet Fins, there are a bunch of
manufactureres that make vented fins in full foot models. Which one is best
for each diver is another question entirely. I don't like vented fins and
never have, so I'll leave the individual choice to those that actually have
some experience to base it on.

I don't think I've ever used a fin that does not work with the frog kick. I
have heard that the split fins do not work with it well, but they're an
offering I've not found a reason to use. In my personal opinion, the
biggest problem with most fins and the frog kick is that recent trends have
been toward fins that provide more propulsion by moving more water and the
whole point of the frog kick is to get some propulsion with minimal movement
of water. It's not fast or powerful, it's safe in an environment where safe
is very important. The bigger and longer the fin is, the more likely the
diver is to let them touch something that they would rather not touch and/or
force a stream of water over something that can be stirred up easily, silt,
for example.

Foot pocket fins seem to be the only practical choice for cold water divers
and are quite popular with warm water divers as well. Some warm water
divers use them because they were tricked by untrue statements that foot
pocket fins are for snorkeling only, but quite a few wear them because a fin
that works with booties makes crossing uncomfortable terrain, rocks, for
example, easier. Full foot fins, traditionally, have been a more efficient
design, giving better transfer of energy than similar pocket/strap fins, but
I've never known that difference to be significant in the real world. If it
were me, and I was a cold water diver even part of the time, I think I'd
stick with the foot pocket fins I had learned to use effectively, but they
would not be Jet Fins. In my opinion, characteristics that make Jet Fins so
good for cave diving, make them a lot less useful for open water. A host of
fin tests seem to agree.

I tried a lot of foot pocket fins over the years. For all around use,
snorkeling and diving, I like my Mares Avante TRE fins better than anything
else I've used. For my spearfishing, I still like Mares fins. This time,
it's their Quatro Power Planas. Mares markets these as freediving fins and
they may, in fact, be good for that. I like their performance and the fact
that they are not as long and cumbersom (on the boat) as more traditional
freediving fins. In my opinion, they give a good combination of constant
power, acceleration and comfort under the water and convenience when packing
and/or kitting up. The trade off is that they do require a bit more
(understatment alert) effort than most divers are used to. They take some
getting used to. They are also a problem for snorkelers. They just don't
work well on the surface, which is why I prefer the TRE's as an all purpose
fin.

I have a pair of v12's. I have no problem with frog kick them, although they
are slightly longer than they should be, they don't cause much downdraft,
and therefore I've never had a problem using them in areas of high sediment.

what lenth should a fin be and why.

Twice the length from the end to the middle

I stand corrected

A gentleman as always.
