The concave terminal of the Fast 400 gives an immediate elastic response to each kick. For this reason, the Fast 400 blade better meets the needs of spearfishing hunters who need a quick start. The 400 foot pocket, is available in 5 different sizes and the dispersion of energy due to unwanted play between the foot and the shoe is minimal. The Fast 400 blade is made 100% of T700 Superforce Carbon fiber (40% more resistant than other standard fibers) and they are inserted in the foot pocket, all the way to the heel for an excellent transmission of energy. The blades are symmetrical, therefore extremely efficient, reducing energy loss.
C4 has developed the DPC (Double Parabolic Curve) design featured by the Fast 400 blades, further enhanced by a special lamination of the layers of carbon. The D.P.C curve optimizes the bending of the blades and the quantity
of water processed. Paired with the elastic-K10 water rails, the combination of these elements optimize the energy produced by the diver’s muscles. This allows for greater speed and therefore safety when diving. The less tired we
are, the safer we can dive. In addition, the less energy we apply on the fins, the longer they will last, in the long term.
The weaving process that C4 applies, layered in a fishbone pattern, greatly reduces friction in the fabric itself, as there are fewer inter-crossings of the fibers.
