A good pair of freediving fins will not only help you dive more efficiently, they look pretty badass! Long and sleek, these fins are designed for maximum efficiency while finning.
Each kick displaces a large amount of water, propelling you forwards with less energy expenditure than a shorter fin would. Because you’re holding your breath during the whole process, you want fins that can transfer the maximum amount of power possible – any wasted energy will consume your precious oxygen.

The latest and greatest pair of freediving fins will undoubtedly step up your freediving / spearfishing game. But remember, some of the most talented divers on earth don’t even use fins! High tech fins can only take you so far – good technique and experience are far more important.
It’s important to realize that not all fins are created equal. Freediving fins differ significantly from your typical scuba or snorkeling fins. This guide will explain how to choose the best freediving fins, and review some of the best fins for different uses.
Why do you need freediving fins?
I can vividly remember the first time I used proper freediving fins. Up until then I had been using cheap open-heel snorkeling fins (the kind that come in an all-in-one snorkeling kit). That day I borrowed a friend’s Cressi Gara’s and the difference was enormous. Finning properly took some getting used to, but after a full day of spearfishing I knew there was no going back – the power I was able to generate with each kick was incredible. I got myself a pair shortly afterwards.
Freediving is unique in its simplicity. You really only need a mask and fins (and maybe a wetsuit and dive float) to start diving. Having a good pair of freediving fins enables you to dive deeper, stay underwater longer and generate more power with each kick.
These fins are built with maximum efficiency and power transfer in mind.
As we all know, any unnecessary energy expenditure underwater will eat up your limited oxygen reserves. You don’t want to be flutter kicking through the whole dive. That’s why freediving fins are so long – longer blades have more surface area – displacing more water per kick.
As your kick transfers power into the blade, it flexes and ‘snaps’ generating a second burst of power. This is especially true for fiberglass and carbon fiber blades – as they’re more flexible than plastic blades.
Top 6 Freediving Fins
How to pick the right freediving fins?
Freediving Blade Materials
There are three main materials used to make freediving fin blades. Plastic, fiberglass and carbon fiber. They vary widely in price, functionality and performance, so let’s break them down one at a time.
Plastic (Polymer) Fins
The least expensive and most common freediving fin material is polymer plastic. Don’t think just because it’s cheaper that it’s a poor choice. These fins are great for beginners, people who use their fins in shallow, rocky environments and anyone who doesn’t want to break the bank on a pair of fins.
Polymer plastic is a tough material, which means it can withstand a fair bit of abuse. If you dive in shallower areas with sharp rocks or coral then consider plastic fin blades. For beginners, plastic blades can help force your legs to gain more endurance as they require more force to fin with.
On the other hand, plastic blades are not as efficient as fiberglass or carbon fiber blades, they’re more rigid and don’t provide the same type of ‘snap’ that high end blades do. They also have a tendency to deform over time, and can become less efficient after a lot of use.
If you dive in cold water conditions keep in mind that some plastic blades have a tendency to stiffen in the cold – which can cause you to expend more energy and slow you down.
The next step up from plastic polymer is a fiberglass fin blade. Fiberglass is an excellent material as it’s highly flexible – yet retains its shape over time. An ideal choice for divers of all experience levels – it’s perfectly balanced in respect to cost, durability and performance.
These fins cost significantly more that plastic ones, but they represent a major performance leap. They have far greater ‘snap’, giving you more power for each kick. They’ll also retain their shape for as long as you use them, giving them a longer lifespan than plastic fins – provided you take care of them properly.
Fiberglass is not as durable as plastic though, so be careful when diving around rocks and other sharp objects.
Carbon Fiber Fins
Carbon fiber is undoubtedly the Rolls Royce of freediving fin materials. It’s lightweight, super flexible, has incredible power transfer, and looks pretty slick too.
Carbon fiber blades provide the most responsiveness of any freediving fin, which means the power from your kick ‘rolls’ through the blade rather than flopping.
Keep in mind though; a pair of carbon fiber fins is by no means necessary for freediving or spearfishing. Sure, it’s technically the best fin material money can buy, but the increased performance you’d get over a fiberglass fin is not that significant for your average diver. Practice and experience are far more relevant factors.
Carbon fiber is also the most expensive fin material (sometimes costing 2 times more than fiberglass), as well as the most fragile. If you plan on using your fins only in clear open water conditions, then carbon fiber may be a good choice. Otherwise a backup pair of fiberglass or plastic fins is a good idea for rocky environments.
Freediving Fin Stiffness
Fin stiffness varies widely by make and model. In general, manufacturers will offer blades in soft, medium and hard.
Blade stiffness really comes down to personal preference. Some divers prefer softer blades, as they require less force to engage, while other divers prefer the power they can generate from stiffer blades.
Stiffer blades will create better propulsion than softer blades – but they require more force (leg and hip strength) to use properly. In general, smaller divers tend to go for softer blades, while bigger people need the extra propulsion, so opt for a stiffer blade.
If you’re buying blades for spearfishing, opting for slightly stiffer blades makes fighting against fish or current easier. Many experienced freedivers also prefer a stiffer blade for deep diving.
Luckily you don’t need to buy multiple fins to take advantage of different stiffness levels. Detachable or modular fins are increasing popular – which allow you to swap out different blades according to your preference.
Modular Freediving Fins (Detachable blades)
Modular dive fins are a great choice for their versatility and convenience. If you’re buying your first pair of freediving fins, modular fins will allow you start out with a cheaper plastic blade and then upgrade to fiberglass or carbon fiber as you progress.
They’re also highly versatile – you can combine different brands of blade and foot pocket to configure your perfect setup. If a blade becomes damaged or worn out, swapping it out with a new blade is fairly simple.
These fins are also great for travelling with. Some freediving fins can measure over 40” long including the foot pocket (which can make them challenging for airplane travel). Being able to detach the blade from the foot pocket means you should be able to fit modular fins inside a larger suitcase.
Foot Pocket Fit
Good foot pocket fit may be the most important factor in selecting a pair of fins. You could have the greatest fins on earth but if they hurt when you wear them, you’d quickly change them for something more comfortable.
The foot pocket should be soft enough to wear for prolonged periods of time, without causing any pain or discomfort from being too tight. A good way to determine the right fit is to try on fins and flex your foot into the swimming position. The fit should be snug but not constricting.
Fit will vary significantly by manufacturer and model, so trying on a pair of fins is really the best way to know if they’ll work for you. If you plan to use dive boots or socks, make sure to try on the fins with the dive socks on your feet – you may need to order one size up.
Ordering one size up is often recommended when buying freediving fins. This allows you to fill in the gap with a dive sock. You don’t want to go too big though, after a certain point power transfer will be affected. The best thing to do is consult the particular manufacturer’s sizing guide.
Blade rails are the rubber liners that run alongside the edges of fiberglass and carbon fiber fin blades. They’re meant to protect the sides of the blade from damage, as well as channel water down the blade more effectively. Rails aren’t strictly necessary, but if I were getting an expensive pair of fins I’d buy them for the added piece of mind.
If you go with modular style fins, it’s important to make sure the rails match the stiffness of the blade. If you have a soft blade with thicker rails, it can make the blade preform like a harder blade.
Maintain freediving fins is fairly straightforward. Plastic fins are notoriously tough and can handle some abuse, but fiberglass and carbon should be handled with a bit more care.
To keep your fins in top shape for as long as possible, make sure to:
- Always rinse off with fresh water after use.
- Dry off blades completely before putting away.
- Store in a dry place out of direct sunlight (too much sunlight can cause some blades to warp)
- Avoid putting heavy equipment or gear on top of fiberglass or carbon fiber fins
- Try to avoid jumping in the water fins first
- Avoid striking sharp things with your blades – the tips are particularly vulnerable to damage

Freediving vs Scuba vs Snorkeling
You might be curious about the difference between the various fins typically used for different activities.
Snorkeling fins are light, compact and designed to be used on the surface or in shallow depths. They’re highly maneuverable so are perfect for exploring around reefs and other tight areas. They don’t require any special technique to use, their short length and flexibility makes them easy for anyone to handle.
Both open and closed heel styles are commonly available.
Scuba fins are longer, wider and usually stiffer than snorkeling fins. They’re built to propel a scuba diver will full gear while at depth. They also commonly have channels or ridges built into them, which assists with moving water away from the diver.
They’re also available with both open and closed foot pockets, depending on the diver’s preference.
Freediving fins represent the biggest difference in fin design. They’re much longer (often exceeding 3 feet) and are fairly stiff in comparison to other fin types. The design is optimized to propel the freediver to ascent / descend quickly, while using the least amount of energy possible.
The added length makes them tougher to use than snorkeling or scuba fins, and requires a different finning technique.
Freediving fins typically have a closed foot pocket design, although you can find a few with an open heel design.
Wrapping it all Up
Hopefully you now have a better understanding of freediving fins and how to select the best fins for you.
It’s important to keep in mind that picking the best freediving fins is a very personal decision. Consider the type of diving you plan to do, and if possible try on any fins before you buy them.
Good fit should be your number one criteria when choosing a fin – it can be the flashiest, newest fin on the market, but if the fit is poor, it’ll be a pain to use.
If you’re looking at fiberglass or carbon fiber blades, keep in mind that the performance jump from plastic -> fiberglass is much bigger than going from fiberglass -> carbon fiber. Going with a fiberglass blade will offer similar performance at a much lower price point.
If you’re buying your first pair of freediving fins, modular fins are an excellent option. They allow you start off with something reasonably priced, and then upgrade to fiberglass / carbon fiber as you progress.
Lastly, don’t get too bogged down in picking out the perfect pair of fins – get out on the water and enjoy yourself!
