The Short Blade Super Flex Fin is designed for swimmers who want a balance of comfort and performance with a bit more snap and drive than Soft Flex. It delivers efficient propulsion with a responsive feel, featuring a soft foot pocket and stiffer rails for added power transfer and control. Super Flex is the sweet spot between comfort and performance—offering more thrust and responsiveness than Soft Flex, while still remaining comfortable for everyday ocean use. The Short Blade design keeps kicks quick and maneuverable, while the Super Flex construction adds extra drive for stronger swimmers and more dynamic conditions. Choose Long Blade Super Flex if you want increased efficiency and distance capability with the same balanced feel.

BEST FOR:

  • Everyday swimmers who want added performance
  • Bodysurfing in varied conditions
  • Ocean swimming with more power and drive than Soft Flex
  • Intermediate to advanced recreational swimmers
  • Longer sessions where both comfort and propulsion matter

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.
