Cressi Reaction EBS Dive Fins in Black/Silver The new Cressi Reaction EBS Spearfishing are some of the most technically advanced fin, the Reaction uses a completely new polypropylene blade material that is more reactive, flexible and trim than previous designs. It kicks easily yet powerfully and is suitable for divers of every experience level. The longer blade efficiently transfers energy from the computer-designed foot pocket, and like other Cressi fins, the blade extends from the top of the foot pocket to maximise its effective surface area for more thrust. Other innovations include new locking strap buckles and anti-slip material for better traction out of the water. Cressi has developed this special strap to meet the needs of the most demanding divers, who need a comfortable fastening for their foot but one that is still practical and manageable. Its special amply-sized slot makes it very easy to put on, even when wearing thick gloves or three-fingered gloves for winter water. The wrapping section is highly flexible, making adjustments unnecessary, and as a result, it’s much easier to get all your equipment right in the first few meters of your descent and the fin stays in place against your foot despite the increase in hydrostatic pressure. Features   Open heel foot pocket fins with elastic bungee strap for scuba diving. The Reaction EBS uses the exclusive Cressi (patented) moulding technology in three materials, ensuring unmatched performance. Polypropylene blades really reactive, and flexible that start directly from the back of the foot pocket. The lightweight blade develops remarkable propulsion with minimal muscular fatigue, enabling to safety face even in a critical underwater situation. The EBS elastic bungee system is easy to put on and ensure a comfortable fastening for the foot. Computer-designed foot pocket made with anti-slip material.
