A revolutionary paddle board fin replacement that only bends to absorb shock when it needs to!
 
Introducing the ultimate solution for paddle boarders seeking unmatched performance on rivers and rocky waters - our High-strength SUP Flex Fin! Crafted from flexible, high-durability Thermoplastic polyurethane, this fin is designed to withstand the toughest river conditions without compromising performance.
 
- Impact-Resistant Rubber: Unlike traditional plastic paddle board replacement fins that can easily crack or break on rocks, our TPU fin flexes and bends to absorb impact, giving you peace of mind in rugged environments. To date, they have held a zero percent failure rate.
Superior Maneuverability: Most flex fins, or "Gummies," have a terrible reputation for maintaining the boat's course. That is why it was so important to engineer a replacement SUP fin that would give when needed and perform like a solid paddle board fin otherwise.
- Easy Installation & Universal Fit: Compatible with most paddle boards, the river fin can be easily installed in seconds, and no special tools are required. Its universal design makes it a perfect fit for any board with a standard slide-in style fin box.
 
-Engineered and manufactured in the USA by aquaholics like yourself!
