Review on Cressi Pro Light Open Heel Scuba Diving Fins: Lightweight and Well-Balanced Made in Italy by John Harvieux

When I switched to these fins I got very bad cramps in my calves and arches. I don't have this problem with my other fins. It feels like the stiff fin combined with the small surface area my foot presses on and the odd fit is twisting my foot in an odd way, causing cramps. I don't recommend them if you have big flat feet like me. (Also, the female part of the plastic buckle is very easy to detach and easy to lose. Because of this, it changes to a star.)
