Aqua Lung Express ADJ Strap Heel Diving Fin

The Express ADJ fin represents the latest advancements in technology and material innovation. This propulsion machine is renowned for its comfort, power, and efficiency. Strap a pair on and experience it for yourself. The Express fin operates on the same principle as the popular Slingshot and Hotshot fins. The function of the Slingshot power bands has been incorporated into the Express "Armadillo". This patented, elongated membrane is crafted from ultra-elastic rubber. Similar to power bands, it accumulates elastic energy during the down stroke and releases 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, eliminating any water transfer through the finite blade connects halfway back on the foot pocket at the Mid-Foot Flex Joint. This design feature prevents hyper-extension of the toes and ankles. The foot pocket is not only comfortable, but it also features different thickness zones that securely attach the foot to the blade for maximum energy transfer. Rubber side ribs channel the water down the length of the fin, minimizing the spill-over effect.

The Express fin is equipped with the ESBS (Ergonomic Strap and Buckle System). The protruding press-to-release buttons can be easily operated even while wearing thick gloves. The strap, made of rubber with anti-aging compounds, has three convenient loops, making it easy to tighten or pull up over the heel, even with the thickest of gloves. The fin also boasts over-sized, anti-slip rubber pads on the bottom for added grip and stability.
