The Aqualung Shot FX Open Heel Fins are designed to give you high-performance and improve your diving experience. These fins incorporate new technologies and the latest materials, taking the best concepts of the SlingShot and HotShot fins and enhancing them. With the Shot FX fins, you'll be able to explore the underwater world like never before. One of the key features of the Shot FX fins is the Power Zone, which is located in front of the foot pocket. In the past, power bands were used in this area, but now, they have been replaced with integrated V Boosters. These boosters provide even more power with less effort, allowing you to glide through the water effortlessly. To ensure a comfortable fit, the Shot FX fins come with a new spring strap. The strap features a soft TPR heel pad and Aqualung's own proprietary buckles, which allow for easy adjustment. No more struggling with uncomfortable straps, these fins will stay securely on your feet, allowing you to concentrate on your dive. The foot pocket of the Shot FX fins is equipped with the Power Transmission Zone. This feature anchors your foot to prevent unnecessary stretching of the foot pocket during the power stroke. This results in maximum energy transmission, allowing you to make the most of every kick. The blade of the Shot FX fins is made with a high-performance elastomer, providing you with excellent efficiency in the water. With each kick, you'll experience a powerful thrust that propels you forward, making your dives more enjoyable and efficient. In addition, the Shot FX fins have an elastic blade insert that creates a spoon effect. This design pushes more water with each downstroke, further adding to the efficiency of the fins. You'll be able to cover more distance with less effort, allowing you to explore more of the underwater world. Take your diving to the next level with the Aqualung Shot FX Open Heel Fins. Experience the power, comfort, and efficiency that these fins offer and make every dive an unforgettable adventure!
