Hey, Lexvil. I love to see other big feety divers. I'm a size 16 and have been looking at the go sport. What other fins have you had success with, and what bc ya got? I'm assuming youre a tall fellow. I'm 6'8" and I'm always trying to find crap that'll fit. Right now I have the atomic split fins. They are a tad small. I also bought the Nova gorilla seawing, but I don't care for the kick action of that super stiff blade.With the go sport I use a boot, the flexible foot pocket allows me to use from 3mm boots up to drysuit boots, with the regular go I use a neoprene sock for multi day diving.
