CRESSI Fin for freediving or spearfishing GARA TURBO BOOST ABH 185036VAR

GARA IMPULSE is undoubtedly the biggest revolution in recent decades in the field of freediving and spearfishing fins, with unprecedented unanimity in the reaction of users of all types and fitness levels. The recalibrated Gara Modular foot pocket's ribs, based on thousands of hours of testing by the Cressi team to define their ideal angle, stiffness, and thickness, combined with the new blade designed with engineering systems to calculate the ideal levels of curvature, angle, and thickness at every point of the blade, have led many to speak of performance clearly superior to many carbon-bladed fins.
New version with a high reactivity, high modulus polypropylene blade and a new design with decreasing thickness (from 4 mm to 2 mm) and a new distribution of the reinforcements, which makes the arching very progressive, canceling the tendency to skid, since the first half of the assembly is more rigid and the final half more flexible.
Shovel with angulation of 29º against the traditional 21 to 23º. This angulation allows kicking with the foot in a completely relaxed position and makes the kicking smooth and comfortable but highly effective both for surface movements and to overcome situations of great resistance to progress such as ascent from the bottom, strong sea or the start of descent with adjusted ballast.
The blade end design has a slight taper and two integrated fins in subtle thermoplastic rubber. This feature, together with the calculated progression of the blade's bending arc, makes the Impulse's flapping stability perfect.

FOOTPOCKET
New design of the horns of the foot pocket with reduced height 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.
Volume of the foot pocket 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 booties
Combine two materials:

A thermoplastic rubber with 75º shore hardness, flexible but inelastic and very resistant, applied to the nerves, 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 transmission of energy.
BLADES: New version with a high-modulus, highly reactive polypropylene blade with a tapered thickness that makes the arc very progressive, eliminating the tendency to slip. The 29º angle, compared to the traditional 21-23º, allows for a fully relaxed foot kick. The blade end is slightly tapered with two integrated fins made of subtle thermoplastic rubber for maximum kick stability. FOOTBAGS: Newly designed guides with modified section, height, and length to optimize the blade's responsiveness, allowing it to define the fin's performance. The new footbath improves blade fixation in the guides, resulting in a smoother and more effective response. It combines two materials with different performance levels and hardness. The instep features a "self-adjusting" band that allows for slight expansion (2-4 mm depending on size) to accommodate individuals with high insteps or when using booties. thick.
