Aqualung Express Adjustable Fins updated

The Express fin is now available in an open-heel version. The Express ADJ fin represents the latest in technology and material innovation. Comfort, power and efficiency are the hallmarks of this propulsion machine. Strap a pair on and seefor yourself. The Express fin works on the same principle as the popular Slingshot and Hotshotfins. The function of the Slingshot power bands has been converted into the Express Armadillo. This patented, elongated membrane is made from ultra-elastic rubber. Like power bands, it accumulates elastic energy during thedown stroke and returns it at the end of each kick cycle. The Armadillo also bridges the gap between the front of the foot pocket and the back of the blade, which eliminates any water transfer through the fin.
