Choosing the most suitable stiffness allows you to adapt responsiveness and movement efficiency in the water to the specific needs of freediving and spearfishing, improving control and fluidity throughout the underwater kick cycle.
Blades for Freediving Fins
The blade is the component that determines the propulsive behavior of a freediving fin. The blade’s material, geometry, and stiffness directly affect the amount of energy transferred into thrust with each fin kick cycle. This selection includes blades in carbon fiber, Innegra, fiberglass, and plastic, from manufacturers specialized in freediving and competitive freediving.
Carbon Fiber Blades
Carbon fiber offers the highest elastic return coefficient among the materials available in this category: the blade stores energy during the loading phase and releases it as thrust during the propulsive phase, reducing muscle consumption at the same speed. The carbon fiber blades in the catalog cover a wide range of geometries and stiffness levels.
C4 offers the MB001 (80 cm) and MB002 (87.5 cm),the L-1090 Freediving and the Sportech Carbonio, all available in multiple stiffness levels.
Cetma is represented with four carbon fiber models: Taras, Lotus Carbonio, Mantra, and Prana. Cetma technology applies differentiated stiffness distribution along the blade axis.
DiveR offers pure carbon fiber blades with the Ultra Carbon, Carbon Copper Purple, and Carbon Tuna Time.
Pathos is represented with three carbon fiber blade models sold separately: Nero', Pro Ultimate, and Carbon Maximum, each available in 2-3 stiffness variants.
H Dessault offers four carbon fiber models with foot pockets included: Fast HD, Pershing HD, Tank HD, and Minimal HD, differentiated by blade geometry and intended use range.
Sigal Sub is represented with the carbon fiber Tsunami, available in 12 size and stiffness variants.
Innegra Blades
Innegra is a high-performance thermoplastic fiber that is laminated into a composite structure to produce blades with higher impact resistance than pure carbon fiber, with a slightly higher weight. It is a suitable choice for use on rocky bottoms or in intensive conditions. DiveR is the benchmark brand for this material, represented with six models: Innegra V2, Innegra Red (long version), Innegra Red Short, Innegra Red-R, Innegra, and Innegra Mermaid Black. All DiveR Innegra models are sold as separate blades, compatible with standard-mount foot pockets.
Fiberglass Blades
Fiberglass offers a more progressive flex than carbon fiber, with a wider margin for technical error. It is a suitable material for divers developing their finning technique and looking for less reactive but more predictable performance. C4 offers two fiberglass models: the FBG Umberto Pelizzari and the FBG Sportech, which combines a Sportech-geometry fiberglass blade with a dedicated foot pocket.
Plastic and Silicone Blades
Plastic and technopolymer blades are the entry point into the discipline: they have a lower cost than fiber blades, greater resistance to accidental impacts, and flexible behavior suited to learning and pool training.
C4 covers this range with the Umberto Pelizzari line in four versions - Black, Aurea, Sideral and Ghost - and with the silicone Wolverine, designed for pool training. Cetma offers the Lotus Plastica, the entry-level version of the Lotus line with a technical polymer blade and foot pocket included. Cressi is represented with the Gara Modular Impulse in two colorways, Blue Metal and Black: modular-system fins with interchangeable blades. Mares offers the X-Wing Pro, mid-range technopolymer modular fins.
How to Choose the Blade
The most critical variable in the selection is stiffness, which should be chosen based on body weight and leg strength. A blade that is too stiff will not flex completely during the kick, reducing thrust efficiency; a blade that is too soft will flex excessively, dispersing energy. Most manufacturers provide weight/stiffness correlation charts for each model. The material should be chosen according to technical level: plastic and fiberglass for those still learning, carbon fiber and Innegra for those who have already developed solid finning technique. Compatibility with the foot pocket is something to verify before purchase for models sold as separate blades.
