The Ocean Hunter SPIRIT Green Fins are European inspired and offer the most versatile range in the world today. The Spirit Fins come in several attractive camouflage colours, representing a different stiffness (rigidity) of fins. Green indicates medium stiffness. This is because stiffer fins usually only result in muscle cramps and earlier exhaustion of the diver. Therefore, with a medium fin, you can stay in the water longer, doing what you love. These fins are also extremely durable and reactive. The unique ribbed fins angle at 20 degrees from the foot pocket for maximum performance. Their innovative foot pockets are made of thermo synthetic rubber with two different grades of hardness. Because of this, Ocean Hunter was able to combine the best in comfort and performance. Lastly, if you are after softer fins or smaller foot pockets, have a look at the Ocean Hunter Spirit in blue . They come in sizes as small as AU 4 / EU 35.
