British high street chain Next has over 400 of their own shoes & boots range in size 9 uk (43 eu) online, although they may be rare in store. They also have footwear in sizes 10-12 UK from other brands including Yours, LTS & various sports brands. Their website navigation is not great on desktop, so I've linked directly to the Next brand size 9s as a starting point. But if you click on view more/all under the size filter list on the left, you can choose other sizes.
