  • Great fins, great value, great company
Color: Single Tab 3-Fin Set - Mint
I recently grabbed these for my Machado Go Fish twinny. I wanted something a little more upright compared to a normal keel template. Traditional keels (like a K2) are great for speed and stability, but not so much for turning and getting spicy with it. These Squared twins are more of an upright template and really loosen the board up. They definitely like to turn! I'd describe them as a solid middle of the road between the hold and speed of traditional keels and the release of a thruster set. It's an ideal combo! The build quality feels super legit. They're easily on par with my Captains. The fit and finish feels high quality, they fit my Futures boxes perfectly, and they have that full fiberglass medium-stiff flex to them. Not to mention the mint color is gorgeous when the sun hits them! All in all, these are an incredible value at about half of what you'd pay from bigger name brands. I also have front and rear traction pads from Squared and everything from them has been really high quality so far. I'll continue to support them as they grow! ... show more

  • Quality fins at an affordable price
Color: Single Tab 3-Fin Set - Mint
Got the blue twin + trailer set. Found these to be well made and aesthetically beautiful fins. Used them without the trailer fin. Had solid hold in steep waves and good release through turns. Really good fins. Read some reviews of others’ experiences with not fitting in the fin box without prior sanding. Was expecting that as well, but didn’t have any issues in my experience. Only wish they had em in the FCS as well for my other twinnie. ... show more

  • Great fins for the price!
Color: Mint Twin Keel Fins
Very well made fins but the length of the base somewhat interferes with the screw sockets. Just need to take the screws out completely to make sure they fit in the fin box all the way before screwing them in. However they work great and all great quality and look nice!

  • Great Set of Fins
Color: Single Tab Quad 4-Fin Set
Great set of quads/keel +2 fin set at a pretty awesome price. Drive/hold/pivot was great in less than ideal east coast winter conditions. Like lots of futures fin-box compatible fins, that first insert might take some wax or a quick swipe with fine sandpaper to optimize fit but otherwise sit flush and no chatter. ... show more

  • Gorgeous Fiberglass Fins, Sturdy Construction, Fit perfect!
I just got these delivered yesterday and finally got to take them out for a spin today! I totally love them! They're super fast, loose, and I'm really stoked with the flex on them. Construction is solid, they're 100% fiberglass and I'm loving having them in my fish. They're loose in the back and drivey when you move your feet forward! Best value for the money you can find. Yewwwwww! Get em!! ... show more

  • Sick Fins!
Color: Single Tab Quad 4-Fin Set
Bought these fins on my wife’s account and had to drop a review because they were so sick! I’m an intermediate surfer and got the future quads for my seaside and beyond and they totally made the board come alive with tons of speed and hold. Have ridden in 2-6ft waves. The fins themselves are well made. Great to see that you can get quality fins for half the price of what other vendors are charging. I’m looking at the twin keels next. I highly recommend these for anyone looking for quality fins and not wanting to spend a fortune. ... show more
