Bio fin cracking.

[eddiesylas]

I bought a pair of Bio Fins each used for my wife and I. New to scuba and not certified yet I had only used the fins in the pool sessions.

I went out to snorkel one time in 51F water for about a half an hour. When I returned to shore the fins are covered in cracks. Is this common? We have our open water test in a few weeks in the same cold water. Should I worry about my wife needing to buy a different fin for these conditions before her's are cracked? Is there a repair I can do to mine. Am I just out $75?

eddiesylas: The bio-fins are made from all natural rubber. Our warranty on new pairs is for one year. The cracking could be due to all kinds of things, extended exposure to the sun, not rinsing the fins with fresh water after use, storing in a garage with exposure to gas or exhaust fumes, etc. Properly maintained the bio-fins will last for many years.

If the cracks are more like creases on the surface of the fin you should be fine. It they have cracked and split you need new fins.
