For what it's worth, I have wide feet. Measuring 4.25 inch at the ball across. Rain works surprisingly well sizing a half size down. I'd be a 8e borderline 8ee US with AE shoes. I went with 7.5 UK Rain to ensure enough width and toe room. The shoe is longer than I would like but it's a chiseled last and is a stronger taper to the toe. I could've probably done 7UK but I opted to have it fit slightly loose than be too tight with width and cramping the toes.
