Have a look for slippers on eBay, Simon. You can sort your search results to 'extra wide' from the side menus. I bought several pairs for my mum while she was in the CH - old feet seem to get wider and wider!
There are lots of styles available, many with adjustable velcro straps so they fit any feet and you can put them on then do them up without the person having to force/squeeze their foot in. Good luck!
