Best Freediving Fins for 2021 Reviewed

1. CETMA Edge

Best Carbon Fiber Fins

If you’re looking for a serious freediving fin, then check out the CETMA EDGE. They have a strong and even stiffness blade.

If you’re looking for a blade that’s a bit shorter, but with the same profile, the Mantra is also a good choice.

Pair it with a custom molded S-Wing foot pocket and you’ll be loving your deep dives even more.

2. Omer Stingray Carbon Fiber

Omer Stingray Carbon Fiber Freediving Fins - 3 Stiffnesses Available (41/42(US Mens's Size 7-8)-25 MD)
  • The new Stingray Carbon fins feature carbon fiber blades...
  • Thanks to this technology the carbon fiber stands are...
  • The under lying result is a very comfortable fin, in part...

The new Stingray Carbon fins feature carbon fiber blades manufactured using the infusion technology with an innovative double vacuum process.

Thanks to this technology the carbon fiber strands are impregnated perfectly in the resin without the risk of forming micro bubble kicks. In addition, the percentage of necessary resin is reduced considerably more than before with a great increase in performance characteristics of the blade.

The specific carbon fiber strand used was developed specifically for the manufacture of freediving fins and patented. The underlying result is a very comfortable fin, in part thanks to the thermo-rubber foot-pockets, providing high performance to the diver.

The interchangeable blades are available in three degrees of stiffness 20 softs, 25 medium, and 30 hard. Aside from not tiring out the diver’s legs while kicking on the surface for extended periods the Stingray Carbon blades push the diver the most during descents and ascents even in great depths.

3. Mares Razor Matrix

Mares Razor Matrix Fin Medium Blade - 43
  • High-Quality Fin Offers Great Performance and Responsiveness
  • Fibers Cross Over Each Other Fewer Times, Increasing...
  • High-Quality Manufacturing Process

These fins are a great budget pair of carbon fiber fins. They don’t have as much power as some of the more expensive carbons out there but they will serve you better than a set of fiberglass or plastics.

These should be for the diver looking for a second set of fins or a travel set. Nothing is worse than having to worry about your gear if you’re shore diving or traveling. The problem is when you bring a set of plastics and realize they don’t give you the power you need for the conditions and you’re put in a bad situation.

Add these to your arsenal and don’t be worried if you damage them.

4. Seac Motus Fibrex

Best Fiberglass Fins

SEAC Motus Fibrex Long Blade Freediving Fins
  • Designed for free diving and spearfishing
  • Interchangeable Fibrex blade made from high-performance...
  • Long blades maximize thrust

The Seac Motus Fibrex Freediving Fins are dive fins that employ an innovative fiberglass compound, comfortable dual-material foot pockets, and high-performance design.

The SEAC Motus Fibrex Freediving Fins are composed of an innovative fiberglass compound with high-performance characteristics. These interchangeable fin blades come mounted in the SEAC full foot pocket, for complete freediving fins set.

The full-foot pocket of these spearfishing fins is constructed in double dual-density materials. The sole and ribbing are hard thermoplastic rubber, with soft thermoplastic rubber for the shoe.

This blend optimizes your comfort and performance ratio for cutting through the water.

5. Omer Stingray Plastic

Most Comfortable Fins

The Omer Stingray Full Foot Fins Fixed Blade is characterized by their Thermo-Rubber Foot-Pocket and for the Angle between Foot-Pocket and Blade. The 22 degrees (compared to traditional 15/17 degree).

With Traditional Fin Blades an Angle between the Heel of the Foot and the Calf of the Leg remains when the Leg is Extended-to-Kick. This Angle causes a loss of Propulsion. The 22 degree Angled Blade Design accommodates for this Anatomical Characteristic and Ensures Maximum Efficiency throughout the Kicking Cycle.

The 22-degree angle results in Optimizing the Power of the Push through the Water Relative to Effort. The use of Thermo-Rubber of Two-Different-Stiffness Compounds Increases Comfort over Normal Foot-Pockets.

The Non-Vented Blades of the Stingray are produced in a Low-Modular Polypropylene Material. Extending from the Foot Pocket are Side Rails which add Stiffness to the Blade and prevent Water from Spilling” over the Outer Edge of the Blade.

The Blade of the Fin is also channeled. The Side Rails and Channels Focus the Movement of Water Down the Surface of the Blade Increasing Power. The Foot Pocket is equipped with a Large Rubber Pull-Tab making Donning-and-Doffing Easier.

The Stingray Fin is Black in color and is covered by a 24-month limited warranty.

6. Cressi Gara 3000 LD

Best Beginner Freediving Fins

Cressi Men's Gara 3000 LD Long Distane Long Blade Diving Fins, 8-9 (with Bag)
  • Designed for Free Divers, Long Flexible Plastic Blade...
  • LD Stands for Long Distance, Increasingly Powerful Fins,...
  • Softer-Blade Great in Cold Water, Cold Water is Notorious...

Gara 3000 Long Distance is Cressi’s entry-level long blade fin designed with softer blades, which make the Gara 3000 LD a perfect choice for the beginning diver or those not familiar using long blade fins.

The LD version originates from the greatly-appreciated Gara 3000 but the material of the blade is softer than the previous version, which makes them stand out. Thanks to the softer blade less muscle effort is required for kicking so divers can use them for longer, making them perfect to use many hours in a row.

The Gara 3000 LD is constructed with durability in mind and long soft plastic blades that can effectively transfer power with minimum effort, which makes this fin very comfortable and easy on the legs for the beginner or during long-duration dives.

The Gara 3000 LD is extremely comfortable and is a full foot pocket style fin. This fin is constructed using Cressi’s unique three material molding process where different compounds bind together to provide flexibility in the foot area and deliver power through the blade due to the stiffness the molding process provides. It can comfortably be worn with or without neoprene socks.

7. Mako Freedive Hunter Fins

MAKO Spearguns Freedive Hunter Freediving Fins (8-9)
  • Freediving Fins with Polypropylene Composite Blades designed...
  • Our foot pockets are soft for comfort where needed, but...
  • These are probably the finest entry level freedive fins...

Mako is known for bringing direct from the factory gear at low prices. These fins are just that, low-cost and durable fins for the new diver.

If you’re looking for a set of fins that won’t break the bank in case you’re not exactly sure if freediving or spearfishing is your thing, then pick these up. They can be resold at a decent price to another diver if you find yourself not enjoying the sport.

8. Cressi Soft Full Pocket Long Blade Fins

These Cressi fins are another low-cost option for the new freediver. These fins are a bit softer than the Cressi 2000HF, which means it’ll put less strain on your ankles. If you’re looking for a pair of entry-level fins that will be kind to your joints, then give these ones a shot.

9. Mares Pure Instinct Razor

Mares Pure Instinct Razor Pro Freedive Fin for Diving or Snorkeling
  • Foot Pocket Incorporates Comfort and Efficiency.One of the...
  • Side Ribs Support Blade, Channeling Water Flow. Side Ribs...
  • Design Consulted by Leading Italian...

These Mares are a great set of fins and I’ve had buddies use them for years before switching. One guy, I know even used them for nearly ten years before the plastic started to get so old that it cracked in half.

You might be wondering why are these so far down the list if they are a solid pair of fins. It’s because they are more on the expensive side for a pair of plastic fins. However, if you do find yourself loving these fins, then they make a good option to grow into them by replacing the blade with a carbon fiber one at a later date. If you want plastic and don’t mind the price, then try these.

10. Beuchat Mundial One Fins

BEUCHAT Mundial One Fins - Black - 47-48
  • Beuchat 'Mundial One', a one-piece fin for both spearfishers...
  • Thermoplastic elastomer footpocket
  • Technopolymer blade

These Beuchat fins round out our top 10 freediving fins. These fins are a solid mid-priced entry-level set of plastic fins and have a wide foot pocket. When it comes to finding the right set of fins it really depends on your foot size and how comfortable you feel diving with them for hours. If you try all the other plastic fins and don’t like them, then this should be your last stop on your journey.

Why Do You Need Freediving Fins?

Freediving Fins That Can Cut Your Kicks in HALF ?!?

The simple answer is to get yourself in a position to shoot more fish on a single breath.

The complex answer is taking into account your skill level, the environmental condition, the comfort of the fins to increase your dive time, how much efficiency you can get out of fins, and the list goes on.

I know a guy who spent a few days with his buddies testing out a bunch of spearfishing fins to see which ones worked the best to try and put to rest the ambiguity of which was the best.

Experience vs. Novice

They realized quickly that dive times were not substantially increased by carbon fins. An experienced large old man using plastic fins will have a better dive time than a young buck repping new carbons. The diver and his technique trump any technology.

I’ve even seen divers in Asian not even use fins and they were deadly in the depths.

The only thing the divers doing the test noticed was that the initial acceleration and the force needed to initiate the dive for the first 10-15 feet showed that the carbons were the quickest. After the diver got past this zone, it didn’t make much difference. Does this mean you should go out and pick up a pair of carbons today?

Maybe if you want that extra second or so of dive time…

Best Freediving Fins

Honestly, if the placebo effect works on you because you bought carbon fins and it increases your dive time, maybe then you should buy them. The reality is that most fins are relatively similar, but costs vary a bunch.

Freediving and spearfishing is a dangerous sport. If you need the most expensive gear to feel like your gear will take care of you…OPT FOR THE EXPENSIVE STUFF. If that’s not something that rests on your psyche, then just get a set that’s robust and spend the saved money on more gear or trips to exotic locations to practice.

Now that we are clear on how you should view fins, let’s dive into the details regarding the various fin features.

Top Freediving Fin Features

Do You Need an Enclosed Foot Pocket?

Most foot pockets are universal in that they will trap your foot to help you drive the power from your legs through the tip of the fin in an efficient manner to propel you forward.

The main things to look for is the wideness or narrowness of the pocket and the firmness of the rubber used.

Remember that most off the shelf fins will require space for a fins sock so if you try on a fin barefoot and it fits great…it might be too snug with the sock.

Freediving Fin Softness

When it comes to material softness, it tends to be a personal preference. You’d probably be better off with a softer footpad as that seems to be correlated with more comfort and longer dive times. The last thing you want is something super stiff that tires out your ankles and legs making you call the dive early.

A good rule of thumb when sizing foot pockets: when trying on the fins, flex your foot to the natural diving position while standing. If your finger can squeeze in the side while flexed, if it feels snug it’s a good fit.

Remember, efficiency is key with fins and a solid foot pocket will help you transfer the power from your legs through the tip of the fin. Not all fin blades fit each foot pocket…ALWAYS DOUBLE CHECK before buying.

Difference Between Freediving Fin Materials

There are three main freediving fin materials:

  • Plastic Blades
  • Fiberglass Blades
  • Carbon Fiber Blades

Plastic Freediving Fins

Plastic blades are the cheapest and least efficient style. They are good for you if you’re a newbie because they are fairly robust and most of the time will weather the barrage of abuse you might throw at them. If you’re a recreational diver, instead of going broke on a fancy pair, try plastic for a while, they’ll get the job done and won’t break the bank.

You’ll notice with plastic blades that when you bend them and let them go, they are slow to bounce back to their original position…this means a loss of efficiency, which adds up with each kick, tiring you out faster.

Fiberglass Freediving Fins

Fiberglass blades are much more responsive than plastic blades. Their response time after being bent to their original position is fast, which means more efficiency from each kick. This is the most noticeable jump you’ll see between fins. If you have plastic fins and switch out your blades to fiberglass you’ll be pleasantly surprised on the added ease for your dives.

Fiberglass fins have less resistance when closer to their original position than carbon does which make them less efficient than carbon. Fiberglass, however, tends to be a bit more durable than carbon fiber for less cost, so keep that in mind…might be worth buying two sets of fiberglass blades for the same price as carbon for nearly the same efficiency.

Carbon Fiber Freediving Fins

Carbon fiber blades are the Ferraris of the spearfishing world. If you have a pair…you’re the cool kid. They are the most responsive from bent to their original position, which means they are the most efficient in transferring energy per kick. If you slo-mo videos of freedivers you can see super long carbon fiber fins have a sinusoidal shape in the water…this role is great at providing thrust to the diver.

Are you going to feel the difference between fiberglass and carbon fiber? Probably not unless you’re a serious freediver. If you’re diving more in high current areas or consistently do deep dives, carbon fiber could make sense, but this is the rarity rather than the norm.

Difference Between Freediving Fin Stiffness

Fin stiffness is heavily dependent from brand to brand and the type of materials being used. Each material is broken down into soft, medium, and hard.

Some manufacturers have poor quality control and a soft in one batch of blades might be more firm than another batch. Hopefully, the brands I’ve picked in this list are not in that camp, but just be aware that it could happen.

Some spearos recommend opting for a slightly stiffer fin because it helps when you need to get a bit more propulsion, especially when fighting big fish.

Therefore, medium to soft is probably the best firmness for most spearos.

Here’s a simple firmness guideline:

  • Diving in current? Use a stiffer blade so you can get more power per kick.
  • Are you a spearo? Use a stiffer blade so you can fight current and fish.
  • Are you a pure freediver and never dive in current? Go for a softer blade depending on how big you are (bigger go a bit stiffer).
  • The deeper you dive the stiffer your blade should be to balance out the lack of buoyancy.

Fin Rails or No Rails?

There is a group of freedivers who believe that having rails on the edges of the fins channel the water through the center giving you more thrust.

You might get a slight advantage, but for most spearos, it most likely will not be noticeable.

Therefore, get them if you want them, but don’t stress about it.

How to Care For Your Freediving Fins?

Taking care of your freediving fins is relatively straightforward…but as always, check with the manufacturer for more details.

For general care:

  • Try not to stand on the fins, especially the tops. The weight could bend or break the delicate material.
  • Don’t leave them in extremely hot or cold areas as the rubber could dry out or freeze degrading the foot pocket. This could also damage the blades.
  • Don’t leave your fins in a hot car because it could deform the materials.

After diving:

  • You are best off rinsing them with fresh water and drying them. Make sure they aren’t wet if you place them in storage. If you do store them, keep them in a cool dark place.

Harmful Chemicals:

  • Try not to get tar, gasoline, alcohol, and a myriad of different chemicals on your fins. This could degrade the various materials and shorten the life of the fins.
  • If you do spill something on the fins, try to rinse it off with water. If that doesn’t work, try soap and water. Try to stay away from abrasive and corrosive solvents like alcohol or paint thinner.

Freediving Fins Buyer’s Checklist

  • If you’re new to freediving or spearfishing, stick with either plastic fins or fiberglass fins.
  • Find the most comfortable foot pocket.
  • Soft to a medium-firm will suit you for most situations.
  • Do your best not to kick the fins against rocks or the reef to keep them from breaking.
  • Once you find a pair you like, pick up a few more for different diving conditions.
  • Make sure you use fin socks unless you have a custom foot pocket.
  • Clean your fins with water after each dive. Make sure you dry them before storing.
  • Don’t keep your fins in a hot car to prevent deformation.

Insider Advice

How many advanced divers do you know spend ages and countless amounts of money to find the perfect pair of carbon fiber fins? There’s no one size fits all for anyone diver and the countless set of conditions you’ll be diving.

The most important aspect of a perfect free-diving fin is the foot pocket. If that’s not comfortable, no fin, whether plastic, fiberglass, or carbon fiber will matter.

Truth be told if you’re a great freediver or spearo and you were great using $150 fins when you upgrade to the $450 fins…they BETTER be great…otherwise why did you spend the money? Are they really great though or do you just think they are great?

Shop On a Budget

That’s why if you look on Craigslist or used dive shops sales, you tend to see a bunch of carbon fiber fins for sale…often cheap!

If you’re saying, “these carbons are the best fins ever,” then why are you selling them after 3 months? You should be saying…” this is the darkest day, after 5 years, I’ve worn these fins down to my toes and I’m still debating keeping them just because it’s like losing a member of the family.”

For performance, it all comes down to what you need to get yourself in the best position at the right time to spear a fish. Do you tend to dive 15 feet, 70 feet…triple digits?

You’re best off with a comfortable set of fins you’re used to. Find a decent pair that you like, then buy a spare. Keep one for your regular diving needs and have a better pair for when you launch off the rocks or kick them around the reef looking for lobsters. If you have the cash, get a third pair for the boat diving and deeper dives.

All for cheaper than one set of the top of the line carbon fiber fins!

We Still Love Carbon Fiber Fins

Carbons fins aren’t all bad and I shouldn’t be bashing them to this extent. They are lighter than fiberglass and plastic fins, they do cut through the water better, they are breakable…but so are plastics if you hit them hard enough.

You just won’t instantly become a better spearo by buying a set of high-end fins.

The only need for carbon high-end fins are if you’re diving deeper than 80 feet, tend to dive in heavy current areas, or you’re going to catch the BFT, Dogtooth, giant tuna, big billfish, or massive grouper.

If you’re new to freediving or spearfishing, the types of fins out there can be daunting:

  • Scuba Fins: Usually don’t have a full foot pocket and are loose to fit a boot.
  • Snorkeling Fins: Short and stiff fins meant for easy movement on the top of the water.
  • Bodyboarding Fins: Usually a super short stiff fin that’s worn on one or both feet to help the sponger drop in on waves.
  • Body Surfing Fins: Similar to the bodyboarding fins and often the same.
  • Freediving Fins: These are mainly what we are going to cover today. Pure freediving fins help divers reach depths with high efficiency.
  • Spearfishing Fins: Similar to freediving fins, but we are looking to add a bit more robustness for the conditions and stiffness for helping bring in the fish (and your speargun or pole spear, mask, and spearfishing wetsuit).

I hope this article clarified the different options you have for choosing your next set of fins!
