We recommend inflating your board between 15-22psi.
For heavier riders, we recommend aiming for 18-22psi, and for lighter riders we suggest 15-18psi.
If you're unsure, aim for 18psi or until you can no longer push down on the pump

Integrated fins can get slightly bent in storage, they can be heated with hot water and reshaped.
The bump on the underside of a board is on every inflatable board and is formed when the threads are removed to insert the valve on the top of the board and there is nothing to worry about.
