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.
