The X-Stream diving fins feature a blade length ranging from 34.5 to 38 cm, depending on the size. These fins have an open foot pocket and are constructed using innovative, high-performance materials. They offer superior thrust and minimize leg fatigue. The materials used provide maximum elasticity, high durability, and resistance to wear. The fins incorporate a special channel thrust system that enhances water movement and increases thrust efficiency. This results in an ultra-high performance fin suitable for even the most demanding divers. The foot pocket has large perforations to prevent the "parachute effect" and the blade's joints absorb kinetic energy. The wide central flap of the blade ensures a strong channelling effect in line with the Superchannel principle.
