MADE in ITALY
C4 has over thirty years experience in designing and manufacturing advanced carbon fiber equipment, in Italy. Our history is at the base of our brand success.
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.
300: HYDRODYNAMICS
Hydrodynamics: an efficient performance is based on resistance reduction. 300 fins elegant shape could have easily been designed by lines of water flowing on your feet without interruptions and only ongoing smooth lines. Hydrodynamics is key to reduce divers’ fatigue and these footpockets shiny look combines beauty and performance.
300: SAFETY & TIME
Blades are connected to the foot pockets by two special Hilo screws, for a better mechanical seal and energy transmission. This mechanical solution, in addition to making blades replacement much easier, prevents blades from being over stressed.
D.P.C. Double Parabolic Curve
The blade works best when it bends completely? From heel to toe !! This is possible thanks to the double parabolic curve of blades, from heel to toe. A neutral intermediate bottom and two progressive declining curves. Thus it fully exploits the shovel and its elasticity.
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.
