SPORTECH carbon fins
The SPORTECH fins are specifically designed for freediving, offering the perfect balance between performance, comfort, and ease of use.
Ideal for extended sessions, they suit a wide range of freedivers — from beginners to experts — and deliver excellent performance both in dynamic and deep diving.
The SPORTECH carbon fins are available in two versions: one with rubber foot pockets, offering greater reactivity and support, and one with silicone foot pockets, designed to provide maximum comfort and a softer fit.
They share many technical features with the PROTECH model, such as the open-heel foot pocket, the anatomical design differentiated for right and left foot, and a monoblock structure that eliminates any empty space, ensuring maximum power transmission with every kick.
Unlike the PROTECH model, designed for extreme performance and intended exclusively for competitive use, the SPORTECH fins deliver high-level performance combined with comfort and accessibility, making them perfect even for intensive non-competitive training.

Another major innovation — introduced for the first time in the industry — is the ability to choose fins made with two different materials, both for the foot pockets (available in extra-soft silicone or medium-hard rubber) and for the blades (in fiberglass or carbon fiber), each offered in multiple stiffness levels.
This allows every freediver to customize their equipment, finding the ideal combination according to their technical needs and level of experience.
A distinctive feature of the SPORTECH fins is the asymmetry of the foot pockets relative to the blade’s central axis: in addition to being differentiated for right and left foot, each pocket is slightly offset inward.
This unique configuration promotes a more natural and compact leg movement during kicking, enhancing hydrodynamics even with the same blade width.
The result is a smoother, more efficient, and harmonious swim, ideal for both dynamic and deep freediving.
