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.
