Collection: BRAND - 3D Fins

Simply put.. these 3D fins are fast, grip and yet release like no others! 

But if you want to know more...

Surfboard fins with dimples creates a turbulent flow. Turbulent flow has more adhesion, so when you start to turn the dimpled foil, the surface delays the flow separation, reducing cavitation (the separation bubble) allowing the foil to maintain performance. 

When the surfer turns at high speeds, the turbulent boundary layer helps the flow overcome an adverse pressure gradient and allows the flow to remain attached to the surface longer than it would otherwise. This reduces drag, increases lift and improves overall performance of the fin design.
