hi again,
ok, so i have a few thoughts/best guess for you with the added info...
the description above makes me suspect a mostly muscular (mm.) origin. of course, with your sports/injury history, joint problems cannot be ruled out (you should, of course, consult your MD/orthopedist to help rule this out).
so here is why i suspect a mm. component. unlike when we are on land, where our muscles contract in combination against a fixed surface to stabilize us upright, in water there are many more degree's of freedom. fins are basically designed to extend our lever arm and surface area to give us more power. even though most of the 'downstroke' of the typical finning techniques should come from the larger muscle groups in your leg, the small mm. are working hard, contracting in all directions against eachother to stabilize the fin against the pressure of the water (and a high pressure at that because of the increased surface area and lengthened lever arm). they are also doing this at the most elongated point in the joint range of motion.
one clue to which mm. are bearing the brunt is your comment about pivoting on the ball of your feet. my best guess is that your inverters and everters (the mm. that roll the sole of your foot in toward midline or out to the side) are getting overworked (leading to hot swollen and painful tissues). many of the muscles and tendons traveling past the ankle going to the foot pass thru small compartments or sheaths. just like the carpal tunnels in your wrists, these areas can be very sensative to swelling (the body's natural response to repair damage) because they are such small spaces. many of our so called pain receptors are simply responding to this change in pressure at these tissues.
even tho your legs might be very strong from years of sports and supporting your frame, that may not be enough when you are using these same muscles in a non-routine way UW.
so what to do... first, i would consider the suggestion above to try our some different fins. try splits, try paddles of different stiffnesses. i have never tried any of the OPB fins personally, but rodales scubalab (FWIW) had mixed feelings on them and specifically commented on stress at the ankles with this type of fin (see the gear review for open heel fins from July 2003). second, consider practicing and switching to a frog kick - at least part of the time - to give those ankles some different angles of pull to help avoid the repetition. third, you could try some strengthening of those muscles in the off season. even just simple isometrics (contract the muscle and hold for a count of 5, then relax) could be the difference. zippsy is right too, balance exercises on one foot (with hand support like a counter top or sturdy piece of furniture for safety of course makes all of those small little intrinsic mm. work. sports med is not my clinical specialty, but my guess is that taping or bracing (strapping) would do little in this kind of environment. the purpose of most braces or taping is to stabilize the joint against the forces incured when you have a potential for one part to be fixed while another moves too forcefully for the soft tissues to withstand and keep joint integrity. this is not usually applicable in the UW environment until you are on the ladder or shore. last but certainly not least, you might try going back to the basics for helping inflammation - RICE - Rest Ice Compression Elevation, or consult with your MD regarding an anti-inflammatory.
hope you find a solution...
