Description: IST's SUMi Innovative Propulsion Efficiency Open Heel Fins are engineered to offer a combination of easy kicking and full thrust.Propulsion optimized design reduces diver fatigue and air consumption6 water channeling guides direct water backward for added power22° blade-to-foot angle provides maximum kick efficiencyOpen heel foot pocket with quick-release strap buckles and extra-large thumb loop for quick donning and doffingMulti-material engineering combines strength and comfortMade to wear with dive booties In SUMi, varying levels of material hardness are employed in an innovative structural design that maximizes propulsion efficiency while reducing diver fatigue and air consumption. Hard material is used on the side ribs, efficiently converting the energy of a kick into propelling power. Medium-hard material is used on the blade to provide flexibility and maximize efficiency of the water channel. Finally, soft material is used in the foot pocket to enhance comfort while ensuring full transfer of power to the ribs and blade. The fin’s super-comfy foot pocket fitting is the result of IST’s 35+ years’ research and manufacturing experience. A comfortable foot pocket can mean the difference between a long, enjoyable day in the water and an outing cut short. We are confident that SUMi will be one of the most comfortable fins you’ve ever tried. The fin blade’s top features 6 water channeling guides to direct water backwards, adding thrust with every kick. The 22° blade-to-foot angle provides the best kicking efficiency.
