This isn't a fault integrated SUP fins are designed to be flexible.
It allows them to be tough, yet easy to roll away with your board. Every now and then, they can lose their shape while your SUP is in storage, so it's worth checking them after long periods in the bag. Follow these simple steps as and when needed:
 
  1. Use a hair dryer or hot water to heat the fins. This makes them flexible enough to bend.
  2. Bend the fins back to their proper position.
  3. Use some tape to hold the fins in place while cooling.
  4. If you're keen to get back on the water, use some cold water to speed up the cooling process..
