Aqualung Slingshot Adjustable Dive Fins Blue Extra Large

Excellent spring for maximum thrust

The Aqualung Slingshot Adjustable Dive Fins are specially designed to help you move through the water with speed and ease - for less fatigue and joint pain. Plus, they come equipped with adjustable fin straps with squeeze-style quick release buckles. Straps have a large pull-tab so you can take them on and off easily.

Power Bands
These fins feature Power Bands made of pure silicone - releasing coiled energy prior to the upstroke, which gives you a great boost of power with each kick.

Mid-foot Flex Joint
The mid-foot flex joint makes each kick more efficient and comfortable. Each kick now comes from your entire leg rather than just the front of your foot - taking the strain off your toes and the top of your ankle for a much larger range of motion and comfort.

Gear Shift
Gear Shift allows you to choose one of three settings to control your energy and effort levels to adapt to different dive conditions. They're easy to shift during the dive, and the changes can be made even with gloves.
