C4 FAST 400 are identical to с C4 INDIAN, where the energy loss due to unstable contact is minimal. These are versatile blades for any spearfishing style.

The FAST 400 blades feature special geometry to further enhance the mechnical and dynamic efficiency. This solution reduces the energy dispersion and the twisting typical for the asymetrical blades. The reduced mechanical load increases the life time of the carbon fibers. 

The U-shaped tip gives immediate ellastic response of the kick. For this reason the FAST 400 blades provide an advantage when a fast start is necessary. 

Thanks to over 30 years of research and multiple world records, C4 developed the DPC (Double Parabollic Curve), which is applied to the FAST 400 blades. This design is now further improved by the lamination of the carbon layers with specific positioning and arranging. DPC optimizes the curving of the blades and the quantity of the displaced water, and in combination with the Elastic-K10 rails the energy transfer and kick is enhanced. This resuts in increased speed and consequently - enhanced safety of the dive. Less fatigue makes the dive safer: this passive safety condition should be achieved in any case.

С4 FAST400 are manufactured of 100% T700 SUPERFORCE Carbon. This material is some 40% more durable than the standard fibers and offers exellent elasticity. The new T700 SUPERFORCE pattern is fishbone layered, which significantly reduces the number of twists, which otherwie cause friction within the fabric itself. This special weave with less twists makes the blades more flexible and efficient due to the reduced energy absorption.

When selecting the hardness, please take into account the recommendations of the manufacturer:

4 400 Footpocket Black

The C4 400 footpockets are undoubteddly one of the best solutions on the market. Manufactured in hermoplastic rubber, the unique design of C4 400 allows the footpocket to weigh only 390 grams. These are the lightest thermoplastic rubber foot pockets on the market today. The ergonomic design is typical for the C4 style. They feature a preformed angle of 3 degrees to enhance comfort and efficiency.

ANATOMY
Comfortable and sturdy with a weight of only 390gr (13.75oz)

MATERIAL
Their reduced thickness and the elastic thermo rubber material make them easy to wear.

PERFORMANCE
The footpockets horns are extended all the way back to the heel for a more efficient transmission of energy. The interchangeable blade is mounted on the footpocket with a safety screw (sold separately).

TECHNICAL FEATURES
WEIGHT: 390gr (13.75oz) in size 42/43
ANATOMY: C4 “Best” preformed at angle of 3°
COMPATIBLE WITH: All C4 blade models. Mechanically interchangeable with a safety screw
MATERIAL: Synthetic Thermo Rubber

SIZING:
Please note that unlike any other footpocket, the standard sizes of C4 400 are set to be worn with a 2-3 mm sock. Therefore, please use the sizing chart below to make sure the footpockets fit well if you are planning to use them barefoot or with a thicker 5-7mm sock.
