C4 200 Footpockets

C4 200 = NO EFFORT

We have designed the 200 with the position of the blade aligned under the metatarsus and not beyond the toes. This allows the diver to naturally keep a straight position, aligned with the direction of movement and his back and forth stride will become perfectly balanced. Simply put, we have prevented resistance due to bad posture.

200 fins are designed “around the man”. The blade is positioned under the metatarsus. The connection shoe-blade is minimal and therefore highly hydrodynamic. The blades feature a controlled curvature close to the foot.

By effectively eliminating the “traditional” resistant surface, the 200 allow the biomechanics of finning to be more agile and not very tiring.

The 200 footpockets, weighing 189gr in size 42-43, are by far the footpockets with the least mass (lighter) in the world and, the difference in mass with heavier shoes, multiplied by 4 and by the number of finning movements performed in a day, result in hundreds and hundreds less kilograms that have to be moved. The result is less effort: it’s mathematical.

The 200 footpockets feature, for the first in the world, the possibility of adjustment. The blades, placed under the metatarsus, can be easily adjusted to three distinct positions (H / M / S) to balance the stride. The derived adjustment is sensitive and can be easily felt.

The 200 series fins have been tested for over 18 months by an international team of divers and in C4 testing lab, by applying three times the force of humans with fatigue tests of over 1.6 million complete cycles.

Two longitudinal fixing screws, with the interposition of a polyurethane “shock absorber” between the blades and shoes, allow quick assembly and protect the blades from abnormal stress.

The 200 footpockets are manufactured with two distinct materials: A soft, thin and ultra resistant TPE is over-moulded on a rigid sole made in PP.

The upper material is softer (65 ShA) for sizes 36/37, 38/39 and 40/41 and slightly stiffer (74 ShA) for sizes 41/42, 42/43, 43 / 44 and 44/45 to guarantee the best comfort and performance.

The 6 threaded brass bushes, that allow to change the blade position, are inserted in the sole during the moulding process. The blade tightening screws also feature an anti-unscrewing thread lock.

3D shaped water rails are applied on the blades by the over-moulding technique developed by C4 specifically for the blades of the 200 series. The O.P.S. (Over-moulding Protection System) of the water rails, protects the blade from impact and damage.

The upper of the 200 is made with a resistant and elastic thermoplastic material that gives great comfort and maximum ease of fit. Thanks to the combination of the C4 anatomy and the calibrated thicknesses, the upper is self-modelling, adapting to the shape of the right and left foot.

The foot, in a relaxed position, is inserted without effort in the anatomically pre-shaped footpocket. There are no constrictions or limits to movement.

The rigid plastic insole transmits all the applied energy flawlessly.

All our testers have defined the 200 fins “addictive” because of the way they have outperformed traditional fins.
