The Cressi Reaction EBS Fins improves on the Rondine by increasing the amount of technopolymers used in its construction. This is combined with an optimal distribution of materials, ensuring maximum energy transfer and thrust from each kick.

The use of Cressi's patented moulding technology also enhances comfort, giving divers a perfect fit that prevents rubbing or chafing even during long dives. The Reaction model also features an open-heel design with an adjustable heel strap for a secure fit. Not only does this help to prevent slipping, but it also improves propulsion while reducing fatigue during extended dives.

The longer and more flexible blade of the Reaction fin provides unparalleled performance - it is lightweight enough for long dives, yet powerful enough to generate a substantial propulsive thrust. This advanced design allows for minimal muscle fatigue, allowing divers to conserve energy while still being able to move quickly and efficiently underwater.

Beginners can benefit from the ease of use and comfortable feel of these fins, while experienced divers can rely on them to provide the power and agility needed to tackle any diving situation.
