The shoes I have been wearing for several years now are the Shimano SH-RP100. When I got them, they were advertised as a wider cycling shoe (although now I don’t see “wide/wider” on any of the search returns for them). I normally wear size 13 (US), and like a bit more width. I had Morton’s Neuroma and they did relieve the pressure that caused that discomfort. It looks like now that they’re billed as indoor spinning shoes. And they may not be the quality you’re looking for. But, they’ve been good for me as a road shoe. Also…have you considered using one of those splints to correct the bunion? — Dan
