Fast 400

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.

FAST400 feature blades that are specifically symmetrical therefore increasing mechanical and dynamic efficiency. This solution reduces energy dispersion and torque forces which are typical of asymmetric geometries.

A reduced mechanical load also increases the duration of the composite fibers.

FAST400 are made in 100% carbon T700 SUPERFORCE.

The T700 SUPERFORCE fiber is 40% more resistant than other standard fibers and it features a high level of resistance and excellent elasticity.

The new weave design of the T700 SUPERFORCE layered in a fishbone pattern, greatly reduces the number of intersections of the weaving that cause viscose friction in the fabric itself. Because the fibres are less.

This special weave, with a reduced number of intersections, makes the blades more flexible and efficient thanks to a reduced absorption of energy.

The advanced concepts behind the 300 2.0 easy fit foot pockets project are all found in the 400 foot pockets, which are made with a traditional Synthetic Thermo Rubber. The 400 foot pockets with their low weight, however, demonstrate jointly how the design skills of C4 do not depend exclusively on refined materials. They are pre-formed by 3 °, have reduced volume and great hydrodynamics, are extremely comfortable thanks to the particular C4 Best anatomy and the controlled deformability of the upper that wraps the foot.

The blades of FAST400 are connected to the foot pocket thanks to a mechanical  insert that is blocked by two special screws that cannot go easily unscrewed, providing a safe and efficient connection.

For easy transportation, FAST400 can be disassembled, so as to reduce their volume and any chance of damage.

FAST400 blades are 786 mm long and 190 mm wide.  The angle of the blades is 29° + 3° of the preformed footpocket for a total inclination of  32°.

The FAST400’s are available in five sizes: 38/39 – 40/41 – 42/43 – 44/45 – 46/47.

The blades are available in two levels of hardness: 25 ( soft ) and 30 ( medium ).

The 300 2.0 easy fit foot pocket is available in 9 different sizes and for each size in 5 different colors: black, white, blue, brown and silver.

The 400 foot pocket is available in 6 different sizes and for each size in 2 different colors: black and white.

All C4 blades models are compatible with both the 300 2.0 easy fit foot pocket and with the 400 foot pocket in all sizes and colors.
