- Reduced Efficiency: The compact design that makes them great for maneuverability can also mean slightly reduced efficiency when compared to long blade fins.
Short blade freediving fins are like the nimble, zippy hatchbacks of the underwater world. They’re easy to handle, versatile, and perfect for recreational dives or when you want agility over sheer power. If you’re planning on exploring tight underwater spaces or prefer a more relaxed diving style, or are planning on taking them on your travels, short blade fins could be your perfect match.
Freediving Fins by Material:
It’s important to note that within each material category, there can still be variations in price based on factors such as brand reputation, design features, and added technologies.
Additionally, specialized or custom-made fins may command higher prices.
When choosing freediving fins, consider your skill level, diving goals, and budget. While carbon fiber fins offer top-tier performance, they may not be necessary for everyone, and lower-priced options like rubber or plastic can still provide a great diving experience. Ultimately, the best fins for you will depend on your individual needs and preferences.
The price range for freediving fins can vary significantly based on the material they are made of. Here’s a general overview of the differences in price range for carbon fiber, rubber, composite, and plastic fins:
Carbon Fiber Fins:
Carbon Fiber Fins: Fins made entirely of lightweight and rigid carbon fiber, favored for high-performance diving.
Price Range: Carbon fiber fins are typically among the most expensive options in the freediving fin market.
The high cost of carbon fiber fins is primarily due to the quality and performance they offer. Carbon fiber is a premium material known for its lightweight, rigidity, and excellent energy transfer, making it a top choice for competitive freedivers. The manufacturing process and craftsmanship involved in producing high-quality carbon fiber fins also contribute to their higher price.
These are fins with blades made of rubber, which provides flexibility and ease of use.

Reasons for moderate price: Rubber fins are less expensive because rubber is a relatively inexpensive material. While they may lack the advanced performance features of carbon fiber, they are popular among recreational freedivers and beginners for their ease of use, comfort, and budget-friendliness. Also, scratching them is not something to worry about.
Fins with blades made from a combination of materials, such as fiberglass, carbon fiber, and resin, to achieve a balance of performance and comfort.
Price Range: Composite fins fall in the mid-range of freediving fin prices.
Reasons for Moderate Price: Composite fins are a mix of materials like fiberglass, carbon fiber, and resin, offering a balance between performance and cost. They are a good choice for divers who want decent performance without the high price tag of full carbon fiber fins.
Fins with blades made of plastic or polymer materials are known for their affordability and durability.
Price Range: Plastic fins are typically the most budget-friendly option among freediving fins.
Reasons for Lower Price: Plastic fins are made from economical materials and are generally mass-produced. They lack some of the advanced features and performance characteristics of higher-end fins but are suitable for entry-level divers and those on a tight budget. Usually, plastic freediving fins don’t have interchangeable foot pockets, which will mean you’ll have to buy new foot pockets if you decide to change the blades for new ones.
It’s essential to consider your individual goals and needs and try out different fin stiffness options if possible. Many divers find that medium-stiff blades offer a versatile compromise between power and comfort for a wide range of diving scenarios. However, ultimately, the ideal stiffness of your freediving fin is a matter of personal preference and can be fine-tuned based on your experience and feedback from your dives.
Different brands have different rigidities and a soft blade from one brand might be slightly different from one brand to the other. Usually you should be able to choose from the following stiffness:
- Stiff/Hard Blade Fins: Fins with blades that are rigid and less flexible, providing maximum power and efficiency. Often used by competitive freedivers for deep dives.
- Medium Blade Fins: Fins with blades of moderate stiffness, striking a balance between power and comfort. Suitable for a wide range of freedivers.
- Soft Blade Fins: Fins with blades that are more flexible, making them easier on the legs and ideal for beginners or those who prioritize comfort over maximum propulsion.
How to Choose the Stiffness of Your Freediving Fins
When choosing the stiffness of a freediving fin, several factors come into play, including your weight, diving goals, and whether you’re spearfishing or line diving. The stiffness of the fin blade can significantly impact your performance and comfort underwater. Here are the key factors to consider:
- Body Weight:
- Heavier Divers: Heavier individuals generally require stiffer fins to generate enough propulsion to move efficiently through the water. Stiffer fins can provide the necessary power to overcome buoyancy and water resistance.
- Lighter Divers: Lighter divers may find it more comfortable to use softer fins because they require less effort to generate adequate thrust. Softer fins can reduce the risk of fatigue during longer dives.
- Diving Goals:
- Competitive Freediving: If you are training for competitive freediving and aiming for depth or distance records, stiffer fins may be preferred. They provide maximum power and efficiency, which is essential for reaching greater depths or covering longer distances.
- Recreational Freediving: For recreational freediving where you’re diving for enjoyment and relaxation, you have more flexibility in choosing blade stiffness based on your personal comfort. Medium or soft blades may be more suitable for leisurely dives.
- Spearfishing: Spearfishing fins often require a balance between power and maneuverability. Depending on your style of spearfishing, you may opt for medium or medium-stiff blades, as they allow you to move quickly while also providing adequate power for breath-hold diving and catching fish.
- Line Diving: Line diving, which involves diving along a guideline for training or exploration, benefits from fins that offer good control and efficiency. Medium or medium-stiff blades are often a good choice for line diving because they provide a balance between power and maneuverability.
- Personal Comfort and Preference:
- Your comfort and preferences play a significant role in selecting the right blade stiffness. Some divers may prefer the responsive and rigid feel of stiff blades, while others might find softer blades more forgiving and comfortable for extended periods underwater.
- Diving Conditions:
- The water conditions and currents at your dive location can also influence your choice. In strong currents or challenging conditions, stiffer fins may help you maintain control and stability.
When buying fins you can have foot pockets with exchangeable blades or others that are built in to the blades. You can usually buy foot pockets separately from your freediving blades. Most plastic and rubber fins come with a bonded foot pockets, which could be of good value for an entry level fin, but will mean that you would have to buy new footpockets when you decide to upgrade your blades.
- Blade Exchangeable Fins: These fins allow you to change the blade while keeping the same foot pocket. This customization option lets divers switch between blades with different stiffness levels. In this way, you won’t have to repurchase a foot pocket when you want to switch for a new blade.
Open or Closed Heel Fins
- Closed-Heel Fins: These fins have a closed foot pocket design. They provide a snug fit and are popular among freedivers who prefer a secure and comfortable fit.
- Open-Heel Fins: These fins have an open foot pocket, similar to those used in scuba diving. They are typically worn with neoprene booties and are favored for their versatility and ease of putting them on.
I have dived with numerous fins of different brands, stiffness and length, and I have found my favorite. I highly recommend Sommerso fins for freediving for several reasons, and I believe you’ll find them to be an excellent choice for your diving needs:
