Karobnske peraje C4 Sideral

Plaćene 500e u Seriole u Splitu. Svaki put temeljito isprane u slatkoj vodi. Imaju male površinske ogrebotine, ali su vrlo sačuvane. Stope C4 350 42/43. Inače nosim 45/46 cipele, a ova stopa mi savršeno pristaje sa 3mm neoprenskon čarapon. I list i stopa su Made in Italy.

SIDERAL HT are extremely bright and shiny. Thanks to these features they increase the safety of deep sea free divers and they also create a "flasher" effect very useful for blue water hunting.

SIDERAL HT features an essential design which is the result of years of study and research in applied biomechanics. SIDERAL HT are ideal for the most demanding freedivers with regards to performance, efficiency and speed.

Thanks to the terminal flap, SIDERAL HT can be used at high speed while spearfishing or free diving.

The 300 2.0 easy fit foot pocket, available in 9 different sizes, prevents dispersion of energy greatly reducing the space between the shoe and foot. Efficiency is therefore maximized.

300 2.0 Easy Fit foot pockets feature a very low mass therefore maximizing the performance by minimizing the effort of the diver.

The new footpockets 300 2.0 Easy Fit, an evolution of C4 300 footpockets, are extremely light, resistant to wear and preformed at an angle of 3°. Thanks to the new fit, named "Easy Fit", and to the new anatomical shape, named "Best", they are very comfortable and easy to wear. They are featured in 9 sizes and, from size 40 to size 44, they are available in every single size.

Sideral HT are made in 100% carbon fiber HyperTech TR50 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 SIDERAL HT. This design has now been enhanced thanks to a special lamination of the layers of carbon, specifically dimensioned and positioned.

The DPC curve optimizes the bending of the blades and the quantity of water processed pairing with the Elastic-K10 water rails optimizing the strength produced by the muscles and articulations.

The level of energy is optimized 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.

SIDERAL HT 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.

SIDERAL HT are made in 100% carbon HT ALU 15 T, aluminised on the surface for a shiny flasher effect. The HyperTech 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 HT ALU 15 T featuring 15mm large bands layered in a fishbone pattern, greatly reduces the number of intersections of the weaving that cause viscose friction in the fabric itself. Because the fibers 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 blades of SIDERAL HT are connected to the foot pocket thanks to a mechanical insert that is blocked by two special screws that cannot be easily unscrewed, providing a safe and efficient connection.

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

SIDERAL HT blades are 1000mm long and 197mm wide. The angle of the blades is 29° + 3° of the preformed foot pocket for a total inclination of 32°.
