So you’re looking at getting into freediving, or perhaps you’re already advanced and looking for a new pair of fins that’ll get you that record depth.
All freediving fins serve the same purpose despite any differences they may have in material, stiffness, or price. They generally have a closed rubber heel and long blade design to propel you with an efficient power transfer from your legs to your fins.
With the variety of products coming on the market annually, choosing a pair of fins can be an intimidating task, but worry not, at Divein.com we’ve done the research for you. By the time you finish reading this all-you-need-to-know guide, you will have a far greater idea of which freediving fins are best for you.
In this article, we’ll go through the best freediving fins on the market.
Buyer’s Guide to Freediving Fins
When you watch all those insane 200m plus depths achieved by freedivers on youtube, what is the first you notice? It’s their fish-like fins!
You can’t help but be mesmerized by the way they parabolically bend when a freediver uses them. Apart from looking cool, have you ever wondered why freediving fins are so much longer than regular swimming or scuba fins? Freedivers actually use elongated freediving fins instead of scuba fins for technical reasons.
Moving through water requires displacing it, and since freediving fins have a bigger surface area, they do it with greater force. Known as the ‘snap’, a freediver gets a second surge of force from the end of the freediving fin’s blade, which makes them more efficient.
However, length unfortunately is not the only criterion to look out for when buying your next pair of freediving fins and the number of options available might be a bit daunting. Here is a guide on what you should look out for when choosing freediving fins:
Blade Types
Fixed Blade Fins
Fins for freediving beginners are generally bi-fins with a fixed blade. This is when the blades are firmly connected to the foot pockets. As an entry-level freediving fin, these fixed thermoplastic blades are ideal. They are cheap and long-lasting, but as you develop, you may discover that they get stiff and less responsive.
Fins With Interchangeable Blades
Due to performance and practical considerations, intermediate and advanced freedivers tend to use freediving fins with interchangeable blades (also known as modular freediving fins). Buying modular freediving fins is a fantastic idea from many perspectives since you can start with the less expensive, less reactive thermoplastic blades and advance to more powerful fiberglass or even carbon blades as you gain experience and control.
An additional benefit of modular bi-fins is that you may purchase the foot pockets and blades separately. This means you can mix and match foot pockets from different brands, or blades from different brands. If in doubt, check with the manufacturer.
Monofins
Monofins are also worthy of mention. They were designed in order to produce maximum power production with minimal effort. CWT (constant weight discipline) fins are mostly used for pool training and competitions as it is difficult to change direction with a monofin. Therefore these are not suitable for beginners or even intermediates as they are not designed for enjoyment and exploration. It’s worth considering keeping monofin training if you feel like you would like to improve your fin abilities.
Material
Blade Materials
Once you have made your decision about the type of blade you want, it will be time to add the material make-up to your decision-making process. There are three main types of materials used in freediving fins and we’ve listed them here with pros and cons, just for you.
| Thermoplastic Polymer (Recommended for beginners) | Fiberglass (Great for advanced freedivers and spearfishers) | Carbon Fiber (Used for competitions) | |
|---|---|---|---|
| Pros | Durable Low price | Very effective Reasonable pricing | Incredible efficiency High performing Light |
| Cons | Less efficient Cold water rigidity | Can be scratched easily | Very Costly |
Blade Stiffness
Having the most expensive blades in the world won’t make you more efficient if the stiffness isn’t right for you. If the blade material is too soft you won’t be able to get much force out of your fins, whereas if they are too hard even the strongest swimmers in the world will exhaust themselves before they hit any kind of record.
There is a common misconception among freedivers that deeper dives require stiffer fin blades. In actuality, the stiffness should match your musculature.
It is suggested that freedivers who are beginners or who weigh less than 150lbs use soft-blade fins. If you are a larger freediver, or perhaps if you are advanced and have developed a good technique with those new calf muscles, medium stiffness is the most popular choice.
Getting the Right Fit
Generally speaking, all freediving fins will have a closed heel foot pocket design for the optimum power transmission and are available in a variety of colors and styles.
Your fins act as an extension of your legs, therefore your foot pockets need to be snug enough to keep your fins in place to transfer as much energy as possible from your legs through to the blade tip. As a rule of thumb, the more comfortable your feet are, the more efficient your strokes will be.
You can tighten them up by wearing thicker neoprene socks or using fin keepers if they’re a little too loose. When it comes to comfort vs power, a high-quality freediving fin will include a softer flexible material at the ankle, bridge and at the toes, but a harder, strengthened material where it counts for better energy transmission.
We usually suggest renting or borrowing a variety of freediving equipment and testing it out before making a purchase.
Finally, always test on new fins before entering the water, and kick your foot a little to ensure they’re not moving at all – getting a blister on your heel is a pretty nasty way to start your day at sea.

The best way to store freediving fins is by laying them flat on a smooth surface to avoid strap damage. Make sure to keep them out of direct sunlight as this will damage the fins over time.
You can bring your freediving fins with you wherever you travel. If the blades on your freediving fins are removable you can take them apart and take them on a plane with you as carry on baggage.
However, if your freediving fins can’t be taken apart, you’ll have to put them in your checked baggage, preferably in a case, so they are not damaged.

The correct way to use freediving fins is through even and controlled fin strokes to ensure maximum propulsion for the least amount of effort.

Freediving fins are so long because they need to displace more water for every kick cycle. This is so that the diver wastes less energy with every kick as they can cover more distance while conserving oxygen and energy. This is especially important when freediving, as you have limited oxygen, and the more energy you use, depletes this reserve.
