T700 CARBON FIBER
A standard stiffness (Tensil Modulus) combined with a 40% higher resistance (compared to the standard) makes T700 High Tensil carbon fiber particularly suitable for more reliable and durable fins. This new line of fins by C4 is manufactured with this T700 composite material. This line of new fins are manufactured with a standard elastic modulus (ability and speed of the material to return to its original position after having been bent) and high resistance (to breakage) carbon fiber. In addition, we have introduced the new large square fabric texture whose fibers are 5 times bigger to improve the performance. The wide bands of the weaving of the T700, compared to traditional carbon fiber cloth, reduce the number of total weaves. Weaves create friction and bend the extremely thin wires of the fiber. Friction and bends, generate negative effects on the performance of the blade. Reducing this effect, by using T700, results in a higher resistance and much better elastic return of the blades, generating more efficiency (more push and less fatigue) when diving.
300: A UNIQUE ANATOMICAL SHAPE
The 300 unique footwear anatomy is obtained by superimposing the shapes of our right and lef anatomical foot pockets, the Mustang, with their 3°angle. Angle also maintained in the 300 foot pockets. The 300 modular foot pocket anatomic shape is designed to tightly fit to the feet so that energy is transmitted on all foot areas. Thanks to this anatomical design, the energy dispersion caused by unwished gaps between foot and footpockets, is the least possible. Force is naturally applied with the least effort. Fitting and comfort are extremely high thanks to the innovative material used to manufacture the 300 foot pocket shoes which also allows for a 7 time higher resistance compared to other traditional materials.
29° + 3° = 32°
The design of modern fins is mainly focused on achieving a better performance by increasing the total angle between the foot and the fin blade. The foot pocket blade angle must be amplified. In case of a low angle, stiffness of blades will result in fins with a reduced performance. Softer blades with a wider agle will result instead, in stiffer fins. C4 footpockets do not create this problem; all C4 anatomical footpockets have a 3° angle. The blade angle is 29°, a value much used on modern fins which determines a greater preload, making the blade more reactive. Such 29° solution, reaches an angle of 32° thanks to the 3° angle of the patented C4 footpockets providing for an excellent kinematic performance.
