 In the past, to dive at very high depths, fin blades, longerons and foot soles had to be extremely stiff. This was the only way to achieve performing fins. Nowadays, blades are soft and performing, therefore modifying the divers’ athletic movement as less effort is required. This is diving, not skiing and not even climbing, where strength is key. Modern blades can bend under few hundreds grams. Stiff foot soles and footpockets are not necessary any longer as they even limit divers’ performance. C4 goal has always been to create products which allow for a fluid and constant movement in water. As a matter of fact, footpockets must serve divers helping them to freely move their feet. This is why C4 300 foot pockets’ calibrated stiffness, in combination with modern soft and angled blades, offer an amazing swimming experience. This is what modern divers require, nothing more than that: a really efficient performance.

The blade works best when it bends completely? From heel to toe !! This is possible thanks to the double parabolic curve of blades, from heel to toe. A neutral intermediate bottom and two progressive declining curves. Thus it fully exploits the shovel and its elasticity.

Lighter and stronger, more responsive and safer. These composite blades are made with carbon fabric HYERTECH – Big Square. The use of the innovative method of production, Spread Tow instead of yarn, optimizes the structure. Less intersection between the fibers and less ondulations greatly reduce the absorption of energy. Using fins this means blade's great reactive elasticity, what else?

 Ancient Romans, 2000 years ago, used to say: “In media stat virtus”, virtue stays in the middle. TUNNEL water rails (patented by C4 ) stand between EVO water rails for fishing and CONSTANT water rails for freediving. They are suitable for long and soft blades. They are designed to create a partial “tunnel” that better directs water when kicking. Preferably to be used with 300 foot pocket fins with short longerons.
