Freediving deep underwater, on a single breath hold, can be an incredibly rewarding experience. Add to that the thrill of pushing yourself further and staying underwater longer than you ever thought possible – this is the world of freediving. But as a freediver dives on just a single breath, they must conserve both their oxygen and energy levels.
An essential tool for helping conserve energy are freediving fins. Freedivers choose specific fins explicitly designed for freediving, and they make all the difference while you’re underwater. But with so many options to choose from, it can be challenging to know what the best freediving fins are.
From monofins to carbon freediving fins – we deep dive into the best freediving fins in this ultimate buyers guide below.

Why Do Freedivers Use Special Freediving Fins?
As a freediver, you have likely watched many videos online of professional freedivers diving to some serious depths. While analyzing their freediving techniques, you probably noticed they are wearing fins specifically made for freediving. These long, flexible fins are essential for freediving – but why is this?
One key reason freedivers wear fins is that they provide the propulsion needed to get through the water. Remember, many freedivers want to dive deep and beat their personal records – and that requires power. Fins provide the extra ‘push’ needed to get further underwater without tiring out quickly.
When we swim without fins, we must use our own power and strength to move through the water. But wearing freediving fins provides excellent leverage and requires less energy to move. As freediving fins are often long (much longer than scuba or snorkeling fins), they require less effort to use. As a result, they need less energy from the freediver – which is ideal when you’re working on a single breath hold.
The best freediving fins are nice and long. This is because they displace more water, creating a larger ‘engine.’ Longer fins create much more thrust than shorter ones and help the freediver maintain good speed and momentum.
Oxygen is essential to the sport of freediving. The more oxygen you can conserve, the longer and deeper you can go underwater. When wearing fins, they help you move through the water faster and with less effort. This means a freediver needs to use less oxygen, thus helping them stay underwater longer. Together with the right breathing techniques, the right fins can extend your dive by many minutes.
Specific freediving disciplines require the diver to wear fins. For example, the Constant Weight (CWT) disciple involves the diver using either monofins or bi-fins to swim down alongside a dive rope. Fins are an essential feature in this discipline and provide the necessary propulsion to compete.
It’s time to pick the best freediving fins for your needs. If you are still unsure what you need exactly, have a look at the sections further down below. Whatever fin you buy, with online shopping, making an informed purchase doesn’t have to be complicated.

Before we look at the best freediving fins in more detail, let’s discuss the two main types of fins: freediving monofins and bi-fins. While they are both designed for freediving, they have notable differences in terms of function and performance.
Freediving monofins are a single fin that encompasses both feet. Wearing a monofin can give the impression of a dolphin’s flipper or mermaid’s tail. This type of fin is usually made from a robust, flexible material such as fiberglass or carbon, and they are designed to be used as one. Serious freedivers often use freediving monofins, as they allow for greater speed and power underwater – which is ideal for competitions.
Monofins are good for those who want to hit record depths when diving in a straight line. But, as your feet and legs are bound together, freediving monofins do require the diver to use a specific diving technique. Known as the ‘dolphin kicking technique’ – this technique can be hard to master and is not ideal for most freedivers.
Bi-fins are long single fins worn on each foot, like a regular pair of flippers. Bi-fins are considered the best fins for recreational freediving, as they allow you to use different swimming techniques. For instance, you can use the traditional ‘flutter kick’ or experiment with different kicking styles. This also makes bi-fins perfect for those who are just starting out in freediving.
Bi-fins allow you to stop and easily maneuver in the water. This makes them an excellent choice for spearfishing and exploring coral reefs. However, bi-fins may not generate as much speed and power as freediving monofins.
Overall, bi-fins are best for new and experienced freedivers, while Monofins are more suitable for those looking to compete and hit record depths.
Not all freediving fins are made equal. Some of the best freediving fins may vary depending on particular elements such as length, material, and flexibility. Before you run into the dive shop and grab any fins, you must know the different types of freediving fins.
Let’s look at the different components that make up freediving fins, so you can find the best pair for your needs:
The average pair of freediving bi-fins will measure around 31-38 inches. As we know, the longer the fin, the more power, and thrust it generates. There are shorter fins available, but these are best kept for training purposes – such as developing your flipper kick technique.
Three main materials are used to create freediving fins: carbon, fiberglass, and plastic. While each does the same job, their weight and strength can differ. Which you choose will most likely depend on your budget and needs.
For the most lightweight yet delicate fins, you should go for carbon. Carbon is the most expensive material and can be used by both competitive and recreational freedivers. As it’s lightweight and designed to generate maximum thrust, it’s ideal for those looking to dive deep.
Carbon freediving fins are notoriously brittle and should be handled with care. If you often travel long distances or dive in rocky areas, you must be extra careful when packing and using them. With this being said, carbon fins offer excellent ‘snap’ and displace an impressive amount of water.
By far the cheapest option, plastic freediving fins are the go-to choice for beginners. These relatively lightweight yet strong fins are usually made from a hard, durable polymer. But as plastic is heavier when compared to carbon fins, they require more effort to move – meaning your energy will deplete faster.
Plastic fins are also not very flexible and can deform easily. However, plastic fins are perfect for those on a budget or who want to try out the sport before investing in more expensive fins.
The middle ground between plastic and carbon is fiberglass freediving fins. These are commonly used among recreational divers, as they offer more thrust than plastic and are cheaper than carbon fins. Fiberglass provides a great snap while diving and is much less prone to damage when compared to carbon fins. Although, we must note they are not as durable as plastic – so be sure to keep them away from sharp surfaces.
Freediving fins come in different levels of flexibility and stiffness. The stiffer the fin, the more powerful the thrust – but these fins are not the best fit for everyone. The flexibility of your fins correlates with your weight, strength, and ability.
- Super Soft: Best for petite divers who weigh no more than 60kg. Super soft fins are very flexible, which makes them easy to control.
- Soft: The best choice for every diver. Soft fins are great for those weighing around 50-70kg. This level of flexibility works for most freedivers and is fairly easy on the legs.
- Medium: A good alternative for those who want a balanced blend of power and control. Medium flexibility fins are a good option for divers weighing over 70-100kg and freedivers who want to push themselves further.
- Hard: Ideal for experienced divers and those who weigh over 100kg. Stiff fins are great for more powerful kicks but require strength and energy to control.
There are two blade choices when picking the best freediving fins. Both fixed and detachable blades offer different levels of performance and control.
Fixed blades mean the blade is attached to the foot pocket. Integrated blades are perfect if you want maximum thrust and speed, as the blade and foot pocket is connected in one piece.
Detachable blades are easily removed and replaced, which means they last longer. Often connected with screws or clips, you can remove the blade for travel – as you can easily fit them in a suitcase or backpack. Plus, if a blade gets damaged, you can simply replace it with a new one. Detachable blades are great for freedivers who want to customize the performance of their fins.
The foot pockets of your fins should fit snugly around your feet. Fins that are too tight may cause cramps, so test out different sizes before investing in a pair. When picking the best freediving fins, you have two choices between foot pockets – open heel or closed foot.
The closed foot is the best choice for freediving. They offer excellent insulation and provide a more efficient kick since all of your foot is in contact with the fin. When choosing the right size fin for your feet, be sure to account for socks – if you decide to wear them.
Freediving socks are snug and fit over your feet, which helps you to keep warm in cold water. Not only that, but they also provide extra protection against cuts, scraps, or blisters from rough fins.
Finally, the most important aspect of freediving is technique. Try to develop a style that maximizes thrust with minimal effort, and find a kick that works for you. We recommend practicing with your fins – from carbon freediving fins to monofins – to understand their differences. This will also help you find your own personal preference. Remember, even the best freediving fins cannot compensate for poor technique.
Choosing the best freediving fins for you will depend on your experience level and your dive style – and of course also on what you like as well as your budget. Whether you want fins for leisurely diving, spearfishing, or intense freediving competitions – there is a fin out there for you.
No matter which fins you choose – from carbon fins to the well-loved Cressi freediving fins – ensure they fit snugly and you feel comfortable wearing them. Most of all, enjoy the experience of freediving with your new fins!
