EXPRESS ADJ SPRING fins

The Express is the latest in technology and material innovation.

Comfort, strength and efficiency are the main features of this propulsion device. Strap them on your feet and see for yourself.

The Express shoes work on the same principle as the popular Slingshot and Hotshot. The spring function has been transformed into Armadillo (Armadillo), a patented elongated membrane made of ultra-elastic rubber. Like the springs in the Slingshot, the Armadillo stores 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 boot and the back of the sheet, reducing water transfer across the fin. The leaf attaches to the boot at its midpoint, which alleviates toe and ankle hyperextension. The boot is very comfortable and features zones of varying thickness for secure foot fit and maximum power transfer. Lateral rubber ribs divert water away from the fin to minimize the spillover effect
