Cressi Reaction Pro Fins

Reaction Pro is a full foot non-vented fin which has been developed after the Rondine. The Reaction Pro is an innovative fin in look and performance. It is molded using the exclusive and patented Cressi system with 3 materials. The three materials consist of a comfortable thermo-rubber (elastomer) anatomic, computer-designed foot pocket. The foot pocket encompasses the foot assuring transmission of the leg-to-fin thrust without loss of energy, adding efficiency to the fining action. The second material is the revolutionary new dual density (techno polymer) polypropylene which forms the blade, and in conjunction with the third silicone based material creates a channeling effect. The channeling effect is the characteristic of the fin that enables a high level of energy to be transferred in both up and down strokes of the kick pattern. The blade originates from the upper part of the foot pocket, with a 20% increase in useful surface area compared to a traditional fin of the same length. The blade also has a differentiated thickness and gets thinner towards the edge to guarantee greater and more uniform bending. The side stringers are made from two different materials that alternate with each other and overlap in different zones to obtain a structure with controlled flexibility in the different areas of the blade. To all these excellent features, Reaction Pro adds a new, longer, more flexible and lighter blade that provides excellent thrust with minimum muscle fatigue and the smallest expenditure of energy.
