Brand new design for this extremely effective and yet very easy to use fin. The special arched profile of the Thor fins combined with the two central ribs promote a significant flow convection effect, known as “spoon effect”, which stabilises and boosts propulsion. Two lateral holes discharge the negative forces typically associated with this area and at the same time make for enhanced stability. The blades are moulded from two different materials for improved reactivity. These fins are perfect for scuba diving, whether you are an experienced diver or a novice.
