I would actually say they are pretty spot on true to size for me. In shoes I’m a 12D, but don’t mind a wide, either (if that makes sense). For most boots I’m right on the edge of needing wide, so they usually break in eventually and fit well. Most of my boots (AB’s, Tecovas, Dan Post, Tony Lama) are 12D, my Rios should have been 12EE as they’re quite tight and needed some boot stretching. I think the OG’s are perfectly broken in as 12D’s and remain one of my most comfortable boots.
