Whats the biggest fins possible for bodyboarding? Mine are the biggest i could find, XL and im a size 13 foot. these still kill and crush the sides of my feet, leading to cramps.
Thats huge. im sure what the biggest ones are, but if it hurts the side of your feet try to find really wide fins. http://bodyboardshop.com/sizing.asp Go to the bottom where the fins are on that page, the biggest size goes up to 14.5 i think.
i wear a 13 xls churchill.....fit fine, even with 5 mil booties. for summer i put fin socks on or use my vipers. if your afraid that going bigger willl be too loose i would try techs since there a soft silicone, might not hurt that much, or take a dremel and carve out some foot pocket out.
I had Tech 2's and they were kinda comfortable, i eventually had to cut holes in them for it not to hurt, but they didnt hurt the side of my feet they hurt the top.
Massive blue/white Makapuus size 13-14 is what you need. Very noticeable size difference. Look at them in a shop first. Bring your boots. SEARCH the threads for more info.
