The biggest problem of freediving is the lack of equipment you need. A good freediving mask and longer fins to propel you faster and deeper are all that is required!
Spearfishing and freediving fins are different from other fins. The first difference is their extended length. They generally have a longer, less complex design than snorkel or diving fins. They are designed for more efficient propulsion. They are thicker and more rigid near the foot pocket than the other outer end of the blade. Their flexibility also helps you go deeper without expending any more oxygen and energy than necessary. In general, the longer the spearfishing/freediving fin is, the greater resistance moving through the water it has. Less energy is needed to move a greater distance as a result, thus conserving breath during your dive.
More durable plastic fins that are less likely to crack or snap are recommended for beginners. As your experience increases, you may choose to upgrade to more flexible and longer-lasting fiberglass or carbon composite fins that allow you to go to even deeper depths for a longer period more efficiently.
Characteristically, spearfishing and freediving fins are compared on their material, durability, and shape, how easy they are to use, and their stiffness and/or flexibility. The best fins are suitable for the type of diving intended as well as the diver’s level of experience.

Expensive freediving / speardiving fins will not make you a better diver. Consider your experience level as well as your leg strength and power before selecting fin material and stiffness. It is also recommended to try your fins on before buying them.
Blades and Foot Pockets
Fin blades may have foot pockets attached or be separate. Attached blades and foot pockets are glued together. Detached blades and foot pockets have fasteners that allow you to travel with your fins more easily. Separate foot pockets are also more convenient when you decide to upgrade or replace your blades. The drawback to having separate blades and foot pockets is the added foot pocket and fastener weight that can slow you down.
Foot pockets should be made of softer material. Some are wider or narrower. They should fit snugly, but not cramp your foot or be so stiff they cause numbness. Check the size. Socks can help when the pocket size is a little big. Oversizing can result in lost power due to the thickness of the material.
Rails / Tendons
Thicker rails, or tendons, make the blades more rigid. Rails that are too soft do not sufficiently support the blade. This can overstress the blade causing it to crack and break.
Types of Spearfishing and Freediving Fins
Freediving and spearfishing fins may be made from:
- carbon fiber.
Polymer (plastic) is the most commonly-used material to make freediving and spearfishing fins. These fins are less expensive and perform well. They are ideal for beginning divers, for those on a budget, or for those that aren’t ready to invest in high-end fins. Polymer fins offer flexible durability, which allows them to better endure travel and underwater bumps and bruises.
The downside is their efficiency. Polymer fins are not as efficient as fiberglass or carbon fiber types, and they do not last as long. Additionally, since polymer is a ply-able material with memory, it will assume a curved shape if it is consistently bent. Eventually the fin becomes less efficient.
Fiberglass fins are more expensive and rigid than polymer ones. They retain their shape even after extensive and rugged underwater use, however. Fiberglass fins can endure underwater rock impacts without chipping or breaking. These fins remain perfectly straight and aligned.
The downside of fiberglass fins may be their price. They are more expensive than plastic polymer fins, but not as expensive as higher-end carbon fiber blades.
Premium, carbon fiber-made, linearly-graded fins are the most expensive spearfishing and freediving fins to buy. They are more efficient and have the highest propulsion to energy ratio. You typically get more kick for your buck! Carbon fiber fins are extremely lightweight. However, they are more brittle and require more care. They are rigid, memory-free, and retain their shape even after many years of use.
What to Look for When Buying Fins
Consider price, your level of diving expertise, and fin features before buying freediving or spearfishing fins.
Consider your budget and how often you will use the fins to determine how much you want to spend. Also consider that overall performance depends more on your freedriving/spearfishing style and capabilities than how expensive the fins are.
Freediving fins typically range from $80 (for plastic) to more than $600 for high-quality, custom carbon fiber. An expensive pair of fins will not improve efficiency if you are just learning or if your technique still needs to be improved.
Are you just learning freediving or spearfishing? Choose the best fins according to your skill level. It is easy to upgrade as you perfect your technique or as your budget permits. There is always the possibility that, if you are a beginner, you may find the sport is not for you. Beginners may choose less expensive, but no less durable, polymer (plastic) fins. These are better for learning and can endure rough underwater impacts and treatment. More experienced and professional divers will want lighter weight, more flexible fiberglass or carbon fiber fins.
Ease of Use
No fins perform equally well on the surface (swimming) as they do underwater (diving). Freediving/spearfishing fins are made for underwater performance. They are not designed for surface swimming and are different from shorter snorkeling or scuba fins. Freediving/spearfishing fins are designed to provide maximum efficiency with easy use. Their blades are longer for better water propulsion. They make transitioning from shorter fins easier.
Foot pocket size is important. Most fin sizes run a bit bigger to allow for divers that wear socks with their fins. To achieve maximum efficiency, your fin should fit snuggly around your foot. Check the manufacturer’s sizing chart to see if they mention that sizes run bigger to allow for neoprene socks. Also check their fin return policy in case the size is not correct.
There are three shapes available. The standard longer, slender blades allow you to impose a more deliberate and efficient pace and motion. This shape also allows better directional control with minimal effort. There are also the fish tail tip and clover tip fin shapes.
Freediving and spearfishing fins vary between 22” – 27” in length. The foot pocket length also varies according to the individual. In general, the average fin length is approximately 40 inches. The longer they are, the more water is displaced, which better propels you through the water.
Flexibility and Stiffness
The fins that have “the best” rigidity or softness are the ones that fit your height, muscle, and body shape.
Freediving and spearfishing fin flexibility varies. For example, fins having a softer blade are better-suited for short-legged divers with less muscle, while a longer blade better-suits a fit, longer-legged diver.
Rails (ribs) add blade elasticity. Generally, a medium-to-soft blade is a good choice. It has adequate bend and enhances your kicks.
Stiffness also varies. Contrary to belief, stiffer fins do not aid deeper dives. Fin stiffness should match the diver’s musculature. A thinner diver or one with longer legs generates less push per stroke than a shorter, stockier diver. The thinner or longer musculature diver, therefore, needs a softer fin. Once technique is mastered, most divers find they perform efficiently using a medium or medium-soft blade stiffness.
The most affordable, most durable, beginner freediving and spearfishing fins are polymer plastic types. They can bend, but safely, and seldom, break.
Carbon fiber fins are on the other end of the spectrum. These are extremely lightweight, provide the best propulsion to energy ratio, and remain straight and stiff. They are also the most expensive. They are fragile and can crack.
Fiberglass fins are in the mid-price range. They are more durable than carbon fiber and won’t bend. They are typically lighter weight than polymer plastic and can also withstand underwater bumps and bruises.
Freediving/spearfishing long blade fins are optimally responsive without requiring more energy. Interchangeable blade models allow you to begin with less expensive polymer plastic fins and upgrade the blades (to fiberglass or carbon fiber) as your skill level improves.
There are many good brands and types of fins on the market. It is up to the individual, their skill level, budget, and use to decide. The common complaint among consumers is size and fit. If possible, try the fins on before buying. Diving socks can sometimes correct fins that are a bit too large. Happy diving!
