Can anyone comment how Allen Edmonds and Cole Haan compare size wise? I wear a 12.5 in Cole Haan, which is about true to size for me. Would AE fit similarly?

Also, when looking on Ebay for Allen Edmonds, is there anything to be aware of in terms of fakes? I'm looking for a pair of the Park Aves in black and/or brown. Figure if they are slightly used they're probably not fake...
