Questions and Answers for Aqua Lung Express Full Foot Fins:
I wear a size 10 medium shoe size. Would I fit better in an 8-9 or 9.5-10.5?
Bill (Certified Scuba Instructor at Scuba.com)
Order according to your shoe size, if you are in between sizes go up to the next closest size. As long as the item is not used in the water you have up to 60 days to refund or exchange it.
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
Fin Care and Maintenance
Care Before and During the Dive
Avoid standing your fins on the tips of the blades for any extended period of time. Avoid hot temperatures and hot surfaces as these can damage the fin. Avoid placing the fins in a car trunk on hot days as the temperatures inside car trunks can exceed the temperature tolerances of the fin and the blades may distort. Care After the Dive:
Rinse thoroughly with fresh water and towel dry before final storage. Storage:
Store in a cool, dry and protected place out of direct sunlight. Chemicals/Solvents:
Avoid any contact with alcohol, oil, gasoline, aerosols, or chemical solvents. Do not expose any part to aerosol spray, as some aerosol propellants attack or degrade rubber and plastic materials. Do not use any type of alcohol, solvent or petroleum based substances to clean or lubricate any part. Do not store your equipment near any oil, gasoline, chemicals, or solvents.
