Squinty Super Flex Long Blade Fins by Yucca

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
