In reply to Littleslip:
You're a bit of a tetchy twit, ask for advice and express yourself poorly (in a way that suggests you might be under a misaprehension), and it's quite right people try to clarify your OP.
Wind your neck in and thank people for their posts!
A quick google will find plenty of shops that stock a size 47 in those boots. If you're in any doubt, go try them on, get expert advice rather than buy off the net, as it's an expensive mistake when you get it wrong.
I'd suggest a trip to somewhere like V12 or Joe Browns in Lllanberis.
