The Scubapro Seawing Nova Fin combines paddle fin power, acceleration & maneuverability with a split fin's effortless efficiency & comfort. Its articulated joint, like that of a whale or a dolphin lets the blade pivot, reducing drag while generating & maximizing thrust. Hinged Blade has a new & enhanced design that has won multiple awards for it's innovation & efficiency. The hinged blade pivots on the foot pockets to store energy & push you through the water. Strengthened design has been enhanced from years of field & laboratory testing to produce the most efficient pivot compared to previous models. Longer Foot Pocket reduces leg strain by producing a larger pivoting point for you with a sloped edge to hold your foot in the pocket; preventing slipping & rubbing. Grip Sole makes walking to the entry point safer & easier. Walking to the entry point from where you kitted up is never easy but the Seawing Nova fins feature an extra grippy sole for added traction on the wettest surfaces. Marine Grade Bungee Heel can be used with one finger for quick & easy donning & doffing. Elastic bungee strap adjusts to your foot size & compensates for any compression at depth; holding your fin in position. The foot pocket's ergonomic toe box is ultra comfortable while the Power Plate footplate extends all the way to the back of the heel, maximizing power transmission while minimizing leg & ankle strain. Co-molded Thermo Plastic Vulcanizate (TPV) heel pad & mid-sole pad with rough surfaces provide an excellent non-slip grip on wet surfaces. The TPV is highly tear resistant & durable. Revised blade geometry: lateral rigidity has been slightly increased to improve alternate kicks & to improve responsiveness & thrust at full power. Built with a space-age Monprene elastomer that is virtually indestructible. Proprietary G4 articulated joint allows the entire blade to pivot & generate thrust. Wing-shaped blade creates a near-perfect balance of stiffness & flex. Variable Blade Geometry wing tips arc upwards, providing more power & increasing stability. Pivot Control technology ensures that the most efficient 45-degree angle of attack is maintained no matter how easy or hard you kick. Marine-grade bungee strap is self-adjusting, comfortable, extremely durable, & makes easy work of donning & doffing the fin. Re-engineered footplate with co-molded Grip Pads provides a dependable non-skid grip on wet surfaces. Specifications Length: 610mm Pair Weight: 1.56kg
