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 ankle and allows the entire foot to be used. This results in incredible comfort.
To bridge the gap between blade and foot pocket an armadillo membrane is used. The armadillo is a patented, elongating membrane made out of super-elastic rubber. It serves two functions:
Accumulates elastic energy during each kick and gives it back at the end of the kick
Make a complete connection between foot pocket and blade, eliminating hydrodynamic gap that water can move through
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
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
