Aqualung Express Black/Silver Fins

Customized techno-polymer alloy blade has a high spring effect and flexibility for excellent responsiveness and acceleration

• Armadillo membrane at the base of the blade absorbs energy during the power stroke, and releases prior to the upstroke for a power boost on every kick
• Rubber side ribs channel water down the length of the fin, minimizing wasted energy from the spill-over effect
• A Mid-foot Flex Joint is used to attach the blade to the side of the foot pocket for efficient energy transfer and reduced strain on the ankles and toes
• Ergonomic foot pocket uses rubber of varying elasticity for a natural fit and comfortable, efficient kicking
• Integrated power transmission belt keeps foot pocket from stretching on power stroke.
• Anti-slip rubber pads on the bottom of the foot pocket provide traction for moving around on boat decks
