The new modular sprint race fin is a shorter version of the impulse fin, which has been a huge success among freedivers all over the world, both among amateurs and among the most demanding professional freedivers. This is also confirmed by the large number of articles dedicated to it by specialized journalists in industry magazines.

The Sprint was designed to meet the needs of freedivers who practice this sport in winter and when a long fin like the Impulse is not necessary. Both fins were designed using expensive finite element software programs that allow the definition of very complex and equally high-performance sections.

The Sprint blade, like the Impulse, is made of a single thermoplastic elastomer, although it would be more correct to speak of an angled underlayer and an overlayer. The underlayer follows the shape and dimensions of almost the entire fin. It has a uniform thickness and a flexible longitudinal propulsion wing of variable length. The so-called overlay, on the other hand, covers the propulsion wing selectively and has a thickness that decreases from maximum to zero in the longitudinal direction towards the tip of the blade. As a result, the fin offers a new way of storing and releasing elastic potential energy, greatly aiding the movement of the freediver's legs and thus ensuring a clear improvement in propulsion performance. When disassembled, the blade and the sock take up the space of a normal snorkeling fin.

Characteristics:

• Excellent propulsive performance without tiring anyone, beginners or professionals
• Certified full contact thermoplastic rubber insole
• Standard blade/string interface with screws under the foot pocket and side clips
• Extremely thin and light blade in a mix of elastomerized technopolymers developed by Cressi with different thicknesses
• Stringer made of technopolymers with high flexural modulus elastomeric loads
• Foot/blade angle of 29 degrees
• All fin components are also supplied separately.
