Innovative structure combining two central ribs in high modulus polypropylene and a central area of the blade in convex section thermoplastic rubber, assembled in a polypropylene blade | Two side nozzles for discharging the associated negative forces | Channeling and acceleration of water flow, which stabilises and increases propulsion in relation to effort | Blade inclination increased by 5% for greater flapping effectiveness | Medium stiffness | Excellent balance between power and flapping comfort | EBS buckle system with natural latex strap: maximum comfort and energy transmission.
