Spearfishing Carbon Fins help.

[Denoski]

I'm getting Carbon Fibre Fins for Spearfishing, The fins i am getting are "C4 Red Falcon" I need to know the stiffness as I have never had Carbon Fins before and size. They do not sell those fins at the shop where I live ( Australia Sydney ) and only sell one carbon fin. (Not sure about name) Can i try a similar foot pocket at the shop as i am getting it online for $446. I do spearfishing with my Dad and just bought a wetsuit 2 piece Torelli for my birthday yesterday, We saw a bullshark (4 metres) it was a thrilling event as it was only passing through. Appreciate if you can help as i do not want to make a mistake, it is expensive.

I recommend a soft fin for spearfishing. It is the most comfortable - and the chances of getting cramp in the calf is less likely with a soft fin.
Best to try the pockets with the sock thickness you use when it's cold. It's fine if you can try the exactly same model pocket.

Make sure that you can return them and get another size if you buy them without trying them. It's better that they are a little big than to tight. You can use a thicker sock if they are a little to big.

How the pocket fits and how much bigger than your normal shoe size you need is very different from pocket type to pocket type and person to person.

Good luck getting the right ones.
