What is GovX ID?

This fin was designed with the Squinty himself, using real-world feedback from time spent in the ocean to dial in performance, comfort, and control.

The Long Blade Super Flex Fin is designed for swimmers who want a balance of comfort and performance with added efficiency for distance and open-water use. It delivers smooth, consistent propulsion with a more responsive feel than Soft Flex, making it ideal for longer swims and varied ocean conditions. Super Flex is the sweet spot between comfort and performance—offering efficient thrust without the stiffness of high-output rescue-focused fins. Choose Short Blade Super Flex if you want faster response, tighter control, and improved maneuverability in shorebreak and surf zones.

BEST FOR:

Open-water swimming and distance training
Bodysurfing in mixed conditions
Longer ocean sessions where efficiency matters
Intermediate to advanced swimmers

Yucca Fins were born from necessity. When Sean Starky couldn’t find fins with the right balance of flex, comfort, and power, he made his own. Yucca Fins are built to move with you—fast, responsive, and reliable in any conditions.

Premium Malaysian Rubber – Durable, comfortable, and tuned for powerful thrust across long sessions.
Anatomical Foot Pocket – Ergonomic, blister-free fit that moves naturally with your foot to reduce fatigue.
Symmetrical Design – No left/right confusion—grab and go (lifeguard approved).
Angled Side Rails – Channels water for increased drive, control, and stability in all conditions.
Multiple Flex Options – Standard, Soft, Super, and Ultra Soft compounds for customized power and comfort.
Buoyant Construction – Floats for easy retrieval in heavy surf.
Drainage Holes - Trapped water won't weigh your fin down.
Traction - Textured "+" pattern on the base keeps your feet planted, even when it's wet.

Love them. Super comfortable, and they perform great. Exactly as advertised. You get to have fun in the ocean, and look cool. Literally living the dream.😎

Love it! Thanks so much for sharing and for being a part of the Yucca Fam, Art!

Yuccas rule

Very nice fins, power and flexibility have found the same home.

My son and I love the performance of our fins! We just got back from Costa Rica where we surfed fun waves. Thank you for the superior product!

What can we say about Yucca that hasn’t already been said? They’re literally the most comfortable fins on the market, and with the rebirth of the longblade, we see true innovation and unmatched quality. I personally own 4 pairs and have given 3 pairs of fins to students and friends. While the fins are absolutely the best, my favorite part of Yucca is the exceptional people that comprise the Yucca family. From Sean, to Primo, to Wiggy, to my brothers Bronson and Uno, these folks are the embodiment of cool people, who love the water. I’m thankful for their quality products and even more thankful to call them friends. When you purchase Yucca fins, you’re doing more than just buying the best fins on earth. You’re joining a family of some of the best people out there.

I've owned probably around 30 pairs of fins in my life including many yuccas. These are easily some of my favorite of all time. Great all around fin for some free diving, Open water swimming and of course body surfing. Very powerful kicks but flexible enough to give great comfort. From my experience it's very hard to find a fin that excels in all conditions and this one does. And last but not least of course it has a really cool color in the tradition of Yucca fins.

Juste received, the rubber quality is awesome. The fins are rigid but not as i thought while being flexible. Of all the fins I have been able to use, these are of better quality and the most powerful. The foot pocket is rigid but soft.
No regrets at all.

Just received, the quality of the rubber is awesome. Standard flex is not as rigid as I thought, and that's good because the palm is solid because of its construction. I've had a lot of fins in the past (bodyboarder, lifeguard, etc.) and these are far more quality and far more powerful than I have tried so far. The foot pocket is very rigid, the bottom too but it is quite confortable. No regrets at all

The perfect combo of comfort and performance. They’re the flex I didn't know existed and now its my favorite for the juicy and the calm days.
Don't forget the pads!!
NEXT LEVEL!

I purchased these for my son for a combination of open water swimming, body surfing, snorkeling, and age-appropriate free diving. He is thrilled. Perfect flex for his size and skill level.

old school Duck Feet but better.

I love them. Thank you

For comparison I have used Duck Feet for 50+ years so I am still adjusting to the flex pattern. They are easy to slip on, comfortable and powerful. I also like the drain hole placement and design. Sand goes out and it's harder for stingrays to sting through them. I think I need to put some heel protection on and make them a little tighter. I am also glad I went with the soft flex, long blade. Regular would have been too stiff.

Thanks for this, Woody. It means a lot coming from 50+ years on Duck Feet! Glad the flex pattern, comfort, and drain design are working for you.

Good call going soft flex/long blade - that combo tends to feel more natural than the fins you've been used to. On heel protection: our fin socks or fin heel savers offer great heel protection and can be easily swapped between pairs. Feel free to reach out to us at info@yuccafins.com, and we can help get your setup dialed in.

Appreciate you giving them a real shot and being a part of the Yucca fam!

Love em' perfect fit and the right amount of flex

New favorites, soft and flexy so they’re comfy but also enough kick to make me feel safe if waves come 👍🫶👌

Stoked on quality and fit. Water still 45 degrees so waiting for a few more weeks to try.
G$

These fins fit!
I have a hard time with fins fitting my feet... wide metatarsal and a narrow heel. These fins fit well and standard flex is perfect amount of thrust for mat riding. Well done Yucca Fins🤙🏼

Great fins, with power and comfort.

Fins are made very well. I don't have much experience using fins so I can't say much more than that except that I need more practice and yes I bought pink because they were on sale. I did love the other colors and wished I didn't cheap out.

Love Yucca fins! 3rd pair I've purchased (bought a pair for my wife and son). Comfortable and efficient - what more could you want.

Great fit - Great looks - Great power

They´ve got some push....

As expected

These are as sick as it gets!!!

These are my second set of Yucca fins. I loved my first set, and I love these too, but my only issue is that they are super tight on the sides of my feet. So about 10-15 mins into any session my feet start to ache really bad (and I don't have wide feet). So I'm only giving them 4 stars. I thought the more I use them my feet would get used to them, but they still hurt. Not sure if there is anything that can be done about it, but really want to love them. Also one of the fin pads on them came off after the second session.
