Go to Cotswold Outdoor & have a proper fitting. They shouldn't do a hard sell, but if you do buy from them they should be able to make lots if adjustments to the boots to make them fit from the start.
They'll price match any other retailer too.
They have very comprehensive boot fit training. They'll know the different brand shapes and will be able to advise which are likely to fit better than anyone here can.
I got my Meindls from them about... 6 or 7 years ago, stretched to fit my wide feet, gave alternate lacing instructions to support ankle but not squash feet, and they're still super-comfy.
