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.
