Hmmm, you have my sympathies as I bought a pair of Forum boots online years ago with similiar problems. I bought the correct size online but wearing them they were clearly too small. I tried removing the pads but it rode better with the pads in. I tried waiting it out but they never improved. my advice is to return them and get a refund if possible. If that is not possible I would ride them a bit to see if they improve and make the change if they don't.
