  • Overview

    "A twin fin that you can push harder, turn tighter, and surf more vertically" - Britt Merrick

    Placing it's self in the middle of the CI family, the BM template has a swept back long leading edge that leads into a full rounded tip. Different from other twin templates, this fin is designed to feel secure when laying into a longer turn or driving hard off the bottom.

    With the CI Twin Pin/CI Mid in mind, the idea was to help anchor the tail to the wave face so surfers could take a more aggressive approach to riding a twin fin.

    • Highest area twin set in the FCS range.
    • The low sweep (rake) and narrow tip means these fins pivot and release exceptionally well, while maintaining incredible trim speed and the ability to quickly break into a turn.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for all board types including fish, funboard and twin fin boards.

  • Performance Glass

    Performance Glass (PG) fins are machine cut from 30 layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.

  • Large - Extra Large (One size suits all)

    New Sizing for Specialty Fins

    You may notice new size ratings for our Specialty Fin Range. Previously, all Specialty Series fins were rated an XL. To better reflect fin sizing, we now have 3 new size categories: S-M, M-L, and L-XL.

    Love them
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

    Effective but may be uncomfortable
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

    Burned my already sensitive feet, too big
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

    Just as good as paraffin wax
    Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
    I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

    Love these!
    Color: Pink & Beige, Size: Small(fits up to size 7)
    Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.
