DAFIN uses the highest quality natural Malaysian rubber in a unique and exclusive manufacturing process that incorporates two different rubber durometers into the finished product. The fin offers rigid strength yet is flexible when needed. There is less drag on the upward kick and leg tension and cramping are reduced. The strap does not bind or blister. DAFIN is one of the lightest bodysurfing fins on the market. Less weight means less tension.
The wedge type fins with low angles on each side are called “strakes”. The strakes act to prevent water from spilling over the outer edge of the fin during the down stroke. Strakes work with a slightly raised V-shaped shoe to create a chamber for maximum acceleration and to allow water to flow over the surface of the fin, resulting in more thrust per kick.
The shoe of the fin is made of low hardness rubber combined with the rest of the fin with high durometer. The shoe is silky soft on the top of the toes and foot to prevent blisters and chafing, while the bottom is stiff to transmit power to the fin. Socks or fin socks are not required for comfort.
At speed, the “strakes” generate a vortex of water from the trailing edge forming a barrier to help prevent water from exiting around the raised shoe, resulting in an element of control and manoeuvrability across the face of a wave or in turbulent water.
