FCS II Surfboard Fin Box - Single Fin Boxes ONLY  

Set to become the new world standard in system technology and performance, FCS II is designed to accommodate all surfers; regardless of their age demographic, surfing genre, or the boards and waves they’re riding. 

Efficient keyless system for quick fin installation and release. The FCS II system requires no grub screws or keys to secure the fins to the board. Fins can be easily inserted and removed in seconds, allowing you to adapt your equipment to the conditions, on land and in the water. Recessed leading edge with flush base connection improves water flow. These features not only create a sturdy anchorage to the board, but minimize water disruption through a more flush and seamless transition between the fin and board surface.

The FCS II System is backwards compatible with all your favorite FCS dual tab Fins. Constructed using a corrosion resistant titanium tension rod, and a rotating, wear-resistant polymer barrel.  When the fin is inserted into the plug the barrel interacts with a groove detail in the fin to lock it into place using a combination of downward and lateral force.

Lightweight Composite Frame encapsulated by high density foam reduces weight and maintains flex.

Best socks for work or working out.
Size: One Size, Color: (015) Tetra Gray / Gray Matter / White Quartz
Great socks. They stay on your heel! Love the material; breathable and not thick. Love the neutral tone colors.

Perfect thickness and soft feel.
Size: 6-10, Color: Halo Gray/Assorted
Why did you pick this product vs others?: Love theses socks.  It's hard to find socks which won't get pulled down by athletic shoes.  These stay put.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.
