DynamicNord Open Heel Fins Superior RF40 Details

The RF40 fin is engineered to turn effort into propulsion efficiently, making each kick feel controlled and powerful. The stiffer blade construction provides enhanced responsiveness, particularly appreciated by divers who prefer a more dynamic and performance-driven fin. Water channel technology helps direct flow along the blade, reducing wasted energy and improving forward movement with every kick cycle.

Comfort is equally prioritised, with a supportive open-heel foot pocket designed for long dive sessions. The bungee strap system allows quick adjustment without tools, making it easy to fine-tune fit for both neoprene boots and drysuit footwear. The oversized heel loop also makes gearing up straightforward, even in colder conditions when gloves are required.

Fins

Fins decide how hard you have to work. The right pair reduces leg fatigue and cramp and gives you control; the wrong pair makes every dive tiring. For UK diving that usually means open-heel fins worn over boots. We stock Apeks, Aqualung, DynamicNord, Fourth Element, Halcyon, Mares and XDEEP. Try them on with the boots you actually dive.
