Best Freediving Fins 2023

Apnea fins or freediving fins are fins with very long blades. We explain what to watch out for in freediving fins

Brief introduction to freediving.

Apnea diving, also known as freediving, is diving with the air you breathe. The diver inhales before diving and only uses this air supply. The time between inhaling and exhaling is known as apnea hence the name.

Freediving is the oldest and most original form of diving. As early as the Stone Age, apnea divers collected mussels, sponges and pearls and hunted fish with spears. Some of the paleoanthropologists (also known as prehistoric anthropology) discuss the theory that large parts of the incarnation even took place aquatically (living in water).

Nowadays, freediving is practiced as a recreational, but also as a competitive or extreme sport. In the leisure area, the main focus is on exploring the underwater world and general conditioning for scuba diving. In competitive sports, on the other hand, deeper and longer apnea times or distances are aimed for through targeted training.


At this point it must be urgently warned against any kind of self-experiments! Not only unsecured dives, but also attempts on land are dangerous with breath hold. Unconsciousness is a life-threatening situation without quick and experienced help. There is an acute danger to life. It is therefore not advisable to try it by yourself!

Blade length

Standard freediving fins measure 31-38 inches (79-97 cm) without the foot pocket. Such long blades displace more water per kick, meaning the diver can move quickly through the water and cover more distance with less time, oxygen, and energy.

Material of Blades

There are 3 different materials available

1. Plastic

Since plastic is a very robust material, the fins are also quite stable and durable. Far cheaper than the other materials but also heavier.

2. Fiberglass

Fiberglass is an artificially produced material that does not exist in nature. The components of this glass fiber reinforced plastic are made up of several materials. The strength of fiberglass can be determined by the different mix and thus also the hardness of the blade.

3. Carbon fiber


is a composite material in which carbon fibers are embedded in a plastic matrix. The matrix is used to connect the fibers and to fill the gaps. The material epoxy resin is usually chosen as the matrix.

✔️ Advantages

Carbon and Fiberglass fins are ergonomic and provide efficient locomotion. The swingback behavior is better than with plastic.

The long fin blades produce good propulsion. Thanks to the large blade, a large amount of power is transmitted into the water with minimal effort.

❌ Disadvantages

of fiberglass and carbon fins are, that they break quite easily and are more prone to damage.

Blade hardness

There are three different degrees of hardness in freediving fins.

  • Soft
  • Medium
  • Hard

Most of you will immediately think I have to have the hard freediving fin. However, this is not always the best solution! Many of the professional freedivers also use soft blades.

It should be said that this also depends on your own body weight, because if someone with a light 70kg and buys a hard freediving fin, this can quickly lead to cramps in the calves. What might be OK on the surface can have a different effect at a depth of 15m! It also depends on the duration of the training because naturally you have to apply a lot more strength with a hard fin, so the training can fall rather short, which is not always optimal.

Interchangeable blades

With many higher quality freediving fins it is possible to exchange the blades. e.g. from hard to soft blades or from carbon to training plastic blades.

Comfort and shoe size

Often the fins are worn with neoprene socks. If that is the case, you have to include the thickness of the neoprene sock in the shoe size.

The rule of thumb is

With 3mm neoprene socks you should buy your freediving fins 1-2 sizes larger.

With 5mm thick neoprene socks you should buy the freediving fins 2-3 sizes larger.

Material of the foot pocket

The vast majority of freediving fins are of the “full foot” design with very stiff foot pockets that serve to reduce weight and maximize power transfer from the leg to the fin.

Most freediving fins have solid rubber foot pockets.
