I wear shoes in sizes 11-11.5 (depending on brand and size). They were originally a size 12 and they were too big. I swapped for 11.5, they fit well (actually a bit bigger but I like it better). And they are wide, but not too wide. So you can probably get whatever size you normally wear (street shoes, not wrestling shoes). A maximum of 1/2 size bigger, but that doesn't have to be the case either.
