Figured I'd resurrect this thread since there wasn't much discussion on this fin when I was shopping. At least not enough to dissuade me from a poor purchase.
Bought a pair of Cressi Pro Light fins in April and took them to Kauai. A few minutes trying them on, while comfortable on dryland, didn't prepare me for their abysmal fit and function in the water. Boxy, oddly shaped foot pocket. Ridiculously stiff, never a fin that you'd want to snorkel with while you aren't diving. First time in the water (snorkelling) they induced a cramp in my foot rapidly, the only relief was to loosen them slightly...and then I promptly lost one in the offshore breakers, at a very critical time. My stupid fault, but nonetheless ended up in a precarious position. By the time I reached the shore I so loathed these fins that it no longer bothered me that a brand new fin that I'd lugged 3000 miles (carryo-on) was irretrievably lost to the Pacific.
Thusly I spent the entire trip borrowing fins, my buddy's Mares Avantis were delightful, a Divemasters's AL Slingshots were quite nice.
