Cressi Sub Cressi Gara Turbo Impulse Spearfishing Fins ABH155036

GARA IMPULSE is without question, the biggest revolution in recent decades in the field of freediving and spearfishing fins, with an unprecedented unanimity in the reaction of users of all types of profiles and physical conditions. The nerves of the Gara Modular foot pocket have been recalibrated based on thousands of hours of testing by the Cressi team in order to define their ideal angulation, hardness and thickness, together with the new blade designed with engineering systems to calculate the levels of curvature, angulation and Ideal thicknesses at each point of the blade, have made many talk about performance clearly superior to many carbon blade fins.BLADE New version of fins with a high-reactivity-modulus polypropylene blade and new design with decreasing thickness (from 4 mm to 2 mm) and a new distribution of the reinforcements, which makes the arc very progressive, avoiding the tendency to skid, since the first half of the set is more rigid and the final half more flexible. Blade with angulation of 29º against the traditional 21 to 23º. This angulation allows a flapping with the foot in a completely relaxed position and makes flapping soft and comfortable but highly effective both for surface movements and to overcome situations of great resistance to advance such as rising from the bottom, strong sea or the start of the descent with adjusted ballast. The design of the end of the blade is slightly conical and integrates two spoilers in subtle thermoplastic rubber. This feature, together with the calculated progression of the blade flexing arc, makes the flapping stability of Impulse perfect. FOOT POCKET New design of the horns of the foot pocket with reduced height and minimized length in order to allow the adaptation of blades at any angle, not interfering with the reactivity of the blade and allowing a greater arc to the blade.Foot pocket volume resulting from in-depth anatomical studies, with volumes proportional to the widening effect caused by the foot pocket depending on the size of the foot, it does not follow a fixed proportion size by size since proportionally a small foot fattens much more than a large one when put on bootiesCombine two materials:A thermoplastic rubber with 75º shore hardness, flexible but inelastic and very resistant, applied to the ribs, the entire sole of the foot pocket and the exclusive support band on the instep designed to transmit the effort immediately without dissipating in rubbery compositions.The rest of the foot pocket (grey area) maintains a semi-flexible shore 65º composition for optimal comfort. This material is alternately extended in the heel area to perform a non-slip function when walking on a boat or on rocks.The instep incorporates a 2 cm wide Self adjusting band in its center, which allows a slight dilation (from 2 to 4 mm depending on size) to adapt to people with high insteps or in case of using thick pumps. The expansion has been carefully calibrated so as not to impair the
