The main feature of this fin is its polypropylene blade that provides an excellent response. And weight is no longer a problem. These fins provide more thrust power to a diver’s kicking, which results into an excellent effort/performance ratio. Special grooving for water channelling moulded on the surface provides outstanding stability and direction. The thermorubber foot pocket (with varying levels of hardness) is very comfortable to wear and a proper fit is ensured by ergonomic design. The heel strap, an exclusive Cressi design, is a special round bungee cord band that perfectly adjusts to all foot sizes and shapes and provides a comfortable, practical and manageable fastening. It features a special ample slot for easy don and doff even when wearing thick gloves for cold-water diving. NEW EBS STRAP: 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.
