H20 Odyssey 2mm Fin Sock Black Foot health is something you don't discuss over a meal, but if we're talking bodyboarding, then it's game on! No one wants their fins to chafe and cut their tootsies! That's where the H2Odyssey 2mmFinSocks come in. Full heel coverage with these for those that want some heel protection, and nice 2mm cushioning are keys to these gems. A rubberized grip pattern on the bottom for the odd walk on rocks/reef complete the package.
