Experience the cutting-edge technology and revolutionary design of the Express fin. Unleashing comfort, power, and ultimate efficiency, this propulsion machine is unlike any other. Strap a pair on and feel the thrill of unmatched performance. The Express fin builds upon the success of the popular Slingshot and Hotshot fins, taking their power bands to the next level with the patented and elongated Express 'Armadillo' membrane. Crafted from ultra-elastic rubber, this innovative membrane accumulates elastic energy during the down stroke and unleashes it at the end of each kick cycle, propelling you forward with exceptional force. Featuring the groundbreaking Express 'Armadillo' membrane, this fin eliminates any water transfer through the blade, ensuring a smooth and uninterrupted underwater experience. Additionally, the Mid-Foot Flex Joint connects halfway back on the foot pocket, preventing hyper-extension of the toes and ankles. Step into the comfortable foot pocket, designed with different thickness zones to secure your foot to the blade with maximum efficiency. With the Aqualung Express Fins, every stroke will be a testament to the excellence achieved through relentless innovation. Make a splash with the Aqualung Express Fins and revolutionize your diving experience.
