Mine actually snapped and broke suddenly on the 4th of July. I own two Oceanika fins, and this was my "less used" of the two.. and I mean, significantly less used. Anyway, I emailed them about it, and there is a 12 month warrenty. I was out of that 12 month frame by 1 month, but they do review each case individually. I had to send in pictures of the fin, the break, the size on the back of my fin, and a ruler next to my foot. They also had me send in the positive reviews I had made/posted about them, and videos where I had mentioned their product. I truly love the Oceanika fins, and I know everything isn't perfect, so though I was disappointed, I had a feeling that things would be resolved. Sure enough, I got this response:

"We have reviewed you case and are please to advise even though you are out of your warranty period we will replace your fin with a new one. We have done this based on the fact you have been such a strong advocate for us and that it is very unusual type of break and we can see that the fin is still in very good condition. So please advise us of your address and confirm the size of fin you would like replaced."

So despite the minor setback on being without a fin, they handled it really well, and I will still advocate for them - I love their product !
