Spearfishing Fins

It goes without saying that on decathlon.com.gr you will find an excellent variety of spearfishing and freediving fins, designed to offer you the maximum possible propulsion, comfort, and hydrodynamics in every dive. Our models cover every level, from your first exploratory excursions to the most demanding dives at greater depths.

Yes, the difference is significant and focuses on length and function. Spearfishing/freediving fins feature very long and relatively narrow blades. Their purpose is to offer maximum propulsion with the minimum possible consumption of energy and oxygen, which is critical when holding your breath, and they are always full-foot type.
Scuba diving fins are shorter, wider, and stiffer. They are designed to offer maneuverability, easy changes of direction, and power to move heavy equipment (tanks, etc.), while they are often open-heel type, adjustable with a strap, to be worn with thick boots.

Your fins should fit securely without squeezing your foot excessively. If they are too tight, they will cause you cramps, while if they are loose, you will lose energy with every kick and they might slip off during ascent.
Extra Tip: Since in spearfishing we almost always wear neoprene socks (usually 3mm to 5mm) for protection against the cold and chafing, you should calculate 1 to 2 sizes larger than your regular shoe size. You can always consult the size guide on each product page to be absolutely sure!

It depends on your level and your budget:
Thermoplastic (Plastic): This is the best choice for beginners and intermediates. It is extremely durable, resists impacts against rocks, and is very affordable. However, it is heavier and tires the legs more easily during long fishing sessions.
Carbon Fiber (Carbon): This is the top choice for advanced divers. It offers the ultimate snap (reactivity) with zero energy loss, making swimming effortless and ascent from the deep much easier. However, it is an expensive material and requires care, as it is sensitive to hard impacts on sharp rocks.

No, long spearfishing fins are full-foot type and are designed to be worn either barefoot (in the summer) or, primarily, with soft neoprene socks without a sole. Hard scuba diving boots that have a rubber sole and zippers do not fit inside the foot pocket of spearfishing fins and are intended exclusively for open-heel strap fins.

Proper care protects materials from wear and ensures they stay like new for a long time! After every dive, rinse them thoroughly with plenty of fresh, cold water to remove salt and sand. Then, let them dry in a shaded and well-ventilated place, and never leave them in the sun, as UV rays dry out the rubber in the foot pocket and alter the blade's properties. Finally, store them in a horizontal position without pressing on their blades or bending them, so they do not acquire a permanent deformation that will ruin their performance in the water.
