FAST400 fins are similar to the C4 INDIAN but they come with C4 400 footpockets. They are versatile, easy to wear and light weight. They have an excellent value for money.
The concave terminal of the FAST400 gives an immediate elastic response to movement. For this reason, the FAST400 gives preference to quick restarts, compatibly with the needs of the spearfishing action.
Thanks to the 400 foot pocket, available in 5 different sizes, the dispersion of energy due to unwanted play between the foot and the shoe is as minimal as possible.
GECKO are made in 100% carbon fiber T700 SUPERFORCE and they are inserted in the foot pocket all the way to the heel for an excellent transmission of energy.
Thanks to more than thirty years of studies and worldwide records, we have been able to develop the DPC (Double Parabolic Curve) design featured by the FAST400. This design has now been enhanced thanks to a special lamination of the layers of carbon, specifically dimensioned and positioned.
The D.P.C curve optimises the bending of the blades and the quantity of water processed pairing with the Elastic-K10 water rails optimising the strength produced by the muscles and articulations.
The level of energy is optimised allowing for greater speed and therefore safety when diving. The less tired we are the safer we can dive: this is the condition of passive safety to be pursued at all times.
