The exclusive “Parabolic pressure control system” is a stiffness system to allows, to the polymeric blade, to bend following a parabolic curve, fitting every depth of swimming. The One blade is absolutely reactive thanks to a bi-concave shape that works like a spring.
The special tail profile helps the blade to avoid the usual “derapage” effect of the standard plastic fins, while the exclusive connection allows a perfect and fluid energy transmission to the blade.
