I have a set of the Carbon fins, Mine are definitely Carbon, as the material is so thin you can see through the blades. And by see through I mean when you hold them up to a light any place where the weave was picked and distorted in fabrication you can see the light. By the sounds of it, where you choose to have a stiffer blade, the only way to do that was to add extra layers. I have cracked mine at the tips, and it was all black inside. Just my thoughts. I agree with you that if you bought a carbon fin it should be all carbon, so in a way you were cheated. I use Leader fins for Lifesaving sports here in Canada.

Let's tell the whole story. I bought Leaderfins stereo carbon fins in more than 2 years ago because they were the only company to allow the customer decide on the blades width and length and cost only 259 Euros... After some time I felt I need softer blades and more efficient fins as a whole. So I noticed the area in front of the toes is bending very little. Meanwhile I tried to learn about carbon fiber features... So I started to carefully and gradually weaken the stiffeners by cutting them and test swimming vertically and horizontally. When I felt the effort to move the fins was decreasing I completely removed the stiffeners. The fins were much much better, until one morning I was showing a friend how not to move his legs before his fins went under water and just when I had my foot in the water and the blade still above the surface as I moved my leg the fin broke where Lubo has shown above - at the bended zone. Of course I overstressed the blades, of course I was experimenting, etc. But, Leaderfins did never mention that they offer essentially fiberglass blades covered with a single (as far as I can see) layer of carbon above and beneath. If I new that I would never do such experiments, I would not even buy those fins... There were other companies who clearly state what are their blades made of... To my letter they answered that fiberglass was added for strength... This is the whole story. I do not think I am going to by anything more from that company. Hi, everybody!

Good of you to post about it. Did he contact leaderfins about this as well? How did he break them by the way? This is not what you’d expect from fins of that price indeed.

How did he break them by the way?
