Choosing the Right Freediving Fins
One of the biggest decisions you have to make is whether you want an open-heeled or close-heeled fin. Most freediving fins are closed heeled because the design offers more power due to a better fit. However, if you have trouble finding fins that fit your feet perfectly, you may wish to go with open-heeled so that you have room for adjustments.
Fit is absolutely the most important part of choosing the right fins, because it will give you more power, and cut down on blisters and cramping. Trying fins on is essential for ensuring that you’re going to have a great freediving session. Make sure that the fit around the heel, and in the width of the foot, is nearly perfect, before committing to a pair of freediving fins. Some fins are designed so that you do not need neoprene socks, but it’s a good idea to try fins on with them to judge how the fit may change.

The next thing you’ll want to consider is the material of the fin. These are usually polymer (plastic), carbon fiber, or fiberglass. Carbon fiber is a very stiff blade, which will give you a lot of power, but can also be very expensive. Fiberglass is a good compromise between the most inexpensive material of plastic, and offers most of the features that carbon fiber can. If you want the stiffest blade, look for the stiffness rating of one to four – the higher the rating, the stiffer the blade.
Once you’ve got the best fit you can find, and you’ve chosen the material you prefer, it’s time to get diving!
