The blade of the Cressi Gara Modular Impulse completes the range of Cressi fins, inserting a bending angle of 29-degrees, which allows you to further increase the dynamic performance of the fin. The elastomer and techno polymers blade has an incredible resistance to any type of shock, impact, or stress, making it almost impossible to break accidentally. Anti-slip water rails prevent water flow from escaping sideways focusing the propulsion performance of the Impulse. The Gara Modular system introduced by Cressi makes this a perfect choice for deep freediving and spearfishing for divers of all levels. The modular design lets the user replace / interchange blades for specific diving purposes, which make the perfect fin to grow with, as the diver can change blades as their skills increase. Any standard fiberglass or carbon fiber long blade will interchange in minutes without any modifications to either. The self-adjusting foot pocket is constructed with the most modern multi compound joining process to deliver a foot pocket that can offer comfort and suppleness around the foot where desired and yet have stiffer compounds under the foot and heel area where power transfer takes place. The angle of the blade provides the ultimate in efficiency during the kick cycle requiring less energy to load the blade. The fin can be comfortably worn with or without neoprene socks. The Rondine tail special design improves fin control and directionality. Gara Modular foot pocket
