    Design details

    250 foot pocket: comfort, lightness and thrust

    Comfort and ergonomics: Preformed 3° angle and elastic polymer, easy to put on and adapt to the foot, soft and flexible on the top.
    Lightness and endurance: Their low mass reduces the energy required for propulsion, resulting in noticeable energy savings and reduced muscle fatigue.
    Power transmission: the rigid inner sole provides a solid connection with the blade. This design without rigid side rails allows the blade to flex freely along its entire length for efficient thrust.

    Integrated rail profile

    These FBG fins feature rounded-section water rails, a new generation of C4’s pioneering innovation. These continuous rails, running from the foot pocket to the blade tip, retain water on the thrust surface and reduce turbulence. The result is enhanced directional stability and maximum reactive thrust.

    What is Fiberglass Prepreg Epoxy technology?

    Premium fibreglass combined with next-generation epoxy resin ensures excellent strength and flexibility. Laminated using the same method as C4’s top carbon models, and paired with the 250 foot pocket, it delivers maximum comfort and highly efficient thrust transmission. The result: durable, high-performance fins offering excellent value for money.

    Why choose a medium hardness (25)?

    The perfect balance between freediving and spearfishing fins, suitable for all levels from beginner to advanced.

    Have you broken your blade?

    The blades of these fins are removable. Our workshops can replace them in the event of breakage or damage, ensuring the longevity and performance of your fins.
