  • Great set of fins!
Color: Twin Tab 3-Fin Set - Mint
I ordered these and they are awesome. Really made the board more responsive and lively. I love the 2 + 1 set up. I’t helped a lot transitioning from mainly thruster set up boards and will def help when the wave are a bit heavier! I got the thrusters in futures for another board they were excellent as well. They had to be shaved down a little bit but no big deal for the price ... show more

  • Good Company
Color: Mint Twin Keel Fins
The fins weren’t right for my board. The company was very kind in reaching out to make things right. I will definitely order from them again. Top notch customer service!

  • Sick Fins!
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

  • 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

  • Great fins for a good price
Color: Single Tab 3-Fin Set - Mint
After not finding anything at my local surf shop, I was on the search for a twin and trailer set and came across these. So far I’ve been very impressed with the fins! Good solid fiberglass construction, stuff but with some gradual flex at the tips. I’m using them in a hypto krypto and they’ve held well in chest to head high, but still loose enough that I can pivot of the trailer fin engage in turns. There was a little sanding necessary to get the trailer fin to sit flush with my center fin box, but other than that they’ve been solid. Will definitely be buying more products from this company in the future. ... show more

  • Good quality fins and a good deal!
Color: Twin Tab 3-Fin Set - Mint
I bought these to replace the outside fins on my surf SUP with a quad setup. They performed really well and seem really stiff and durable. Overall very happy. 🤙😊
