This K4 Flexy is the original performance fin from K4. It's amazing for use in windsurf, SUP and even longboard surf boards.
This K4 Flexy fin is a great fin to have in your quiver if you multi-watersport.
For SUP, we’ve found these great to loosen up big boards when surfing. The original supplied fins from the brands often use G10 which are fine on flat water, but can be stiff in waves.
For Surfing, these are a cheap replacement or spare for longboards. They can be a really nice alternative as they grip really well while your board still feels loose underfoot.
For windsurfing, these are particularly sweet when used as twin fins, as they eliminate that unwanted top turn spin out. This is the original K4 fin for performance wave riding and one of the first choices for pro team riders when using twin, quads or thrusters.
We supply these as SINGLE fins…1 fin supplied. Please add a second if you need a twin fin setup.
Available in US-Box and Slot Box mostly. Some sizes in mini-tuttle also.
NOTE: If the fin you need is showing as “Sold Out”, please email us at: info@bigsurfshop.com. Our stock changes regularly, and we receive regular deliveries of these, so it shouldn’t take too long to supply you with what you need.
