FCS II Nathan Florence Performance Core Thruster Fins Size:Medium Walden's patented concave bottomDesigned in collaboration with Pro Surfer Nate Florence Overview He's a slab hunter and a big wave lord, but Nate Florence also surfs the same everyday waves as us. When he does, it's the accelerator templates that he clicks in his boards. The template is designed for a balance of speed, flow, and response with added control. It's an oversized, all round template with a fuller tip for surfers who like to attack the wave and perform aggressive turns.
