These are prototype fins we made working on different densities in the material. They are roughly negative 1 to negative 1.25lbs per fin, depending on fin size and water density.
These are a limited run, once they are gone, they are gone! So if you need negative Eddy fins and want them in black, get them while you can!
We have less than 100 pairs of these in total, across all sizes.
Yes, they cost a little bit more, but they cost a little more to make, as material is purchased by weight!
