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 see for yourself. The Express fin works on the same principle as the popular Hotshot fins. 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 the down 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.
- Fully adjustable foot pocket to be worn with boots / booties
- High efficiency using more of the fin to propel diver forward
