AQUALUNG Express Fins White Arctic, EU 46-47

This high performance, full-foot fin is based upon the Slingshot technology coupled with the latest in materials innovation. The result is comfort and performance. The blade is not directly attached to the front of the foot pocket. The fulcrum point is at the patented mid-foot location, known as the Mid-Foot Flex Joint. This takes the strain off of the toes and ankles, and allows the entire foot to be used, resulting in incredible comfort. Features: Foot pocket: - Made with different thickness zones for better transmission of power from leg to fin. - Integrated power transmission belt keeps pocket from stretching on power stroke. - Low profile eliminates drag and turbulence. - Large rubber side ribs are high enough to channel water flow down the blade without letting water “spill” over the edges. Materials used: - Blade made of customized techno-polymer alloy that has high spring effect and flexibility to maximize acceleration. - Strong side ribs and rubber inserts on blade are made with a elastomeric compounds, customized for Aqua Lung to provide maximum elasticity. - Foot pocket made with rubber of different elasticities
